xfs_repair fails after trying to format log cycle?

Hello,

I have an mdadm array with a xfs v5 filesystem on it and its begun to give me issues when trying to mount it as well as complete xfs_repair. Not sure if anyone might be able to shed some light on what is going on or how to correct the issue?

When I try and mount the fs, it complains with:

[  388.479847] XFS (md2): Mounting V5 Filesystem
[  388.494686] XFS (md2): metadata I/O error: block 0x15d6d39c0

[  388.495018] XFS (md2): log mount/recovery failed: error -5
[  388.495090] XFS (md2): log mount failed

This is where its not making any sense for me, If I try and run "xfs_repair /dev/md2" it fails with:

Phase 1 - find and verify superblock...
- reporting progress in intervals of 15 minutes
Phase 2 - using internal log
- zero log...
xfs_repair: read failed: Input/output error failed to find log head
zero_log: cannot find log head/tail (xlog_find_tail=-5)

fatal error -- ERROR: The log head and/or tail cannot be discovered. Attempt to mount the
filesystem to replay the log or use the -L option to destroy the log and attempt a repair.

But if I run "xfs_repair -L /dev/md2" which gives:

Phase 1 - find and verify superblock...
- reporting progress in intervals of 15 minutes
Phase 2 - using internal log
- zero log...
xfs_repair: read failed: Input/output error
failed to find log head
zero_log: cannot find log head/tail (xlog_find_tail=-5)
xfs_repair: libxfs_device_zero write failed: Input/output error

then try and re-run "xfs_repair /dev/md2" it starts traversing the filesystem all the way to "Phase 7" then errors with:

Phase 7 - verify and correct link counts...
- 14:36:55: verify and correct link counts - 33 of 33 allocation
groups done
Maximum metadata LSN (64:2230592) is ahead of log (0:0). Format log to cycle 67.
xfs_repair: libxfs_device_zero write failed: Input/output error

Yet at this point I can now mount the filesystem..

Checking the drives with smartctl shows no errors nor does 'dmesg' show any hardware i/o or controller related errors...

I've tried scrubbing the array and no bad sectors are found either..

I'm running kernel 3.19.8 with xfsprogs 4.5.

Thanks,
Andrew

Your kernel is old enough that runtime probably won't complain either way (note that 3.19 might be considered a fairly early kernel for using CRC support). Perhaps the first write attempt zeroed enough of the log before it failed that log recovery wasn't required, and thus these problematic I/Os were avoided.

What's the history of this fs? Has it been working for some time, just recently formatted? What lead to the need for log recovery? What's the mdadm --detail info, member device size, total array size, xfs_info of the filesystem, etc..?

Does xfs_repair run clean at this point? If so, does 'xfs_repair -L' still reproduce the write error (note that I'm assuming you have a clean log such that this command will not cause data loss). If so, an strace of the repair process might be interesting...

The filesystem is about a year old as I had one of the Addonics backplane boards go bad and after the replacement all was good again.. until the RocketRaid 2722 card and its obscure "Task File error" error message came up again.

Everything up to this point had been working smoothly since end of Sept 2015 after the rebuild. All disks are 2TB in size, partitioned via 'parted' with 0% and 100% used for partition boundaries on each drive. Everything had been working wonderfully long before but the array was taken out due to some issues I had with 3 hitachi drives that refused to work on the RR2722 card/drivers. Long story.

I've swapped out two drives in the array and no luck yet as it doesn't seem to be hardware failure related.. I've not had any signs of data corruption, just meta-data corruption/errors.

If I remember correct, the format applied to the array was done under 3.6.11 kernel as
I'm still going through the same xfs_repair as above to get the array to mount. It keeps failing after it tries to format the log to cycle 67.

I'll see if I can get you an strace of things.

This all began when the RR2722 driver running under 3.18.15 complained and ..

The filesystem is about a year old as I had one of the Addonics backplane boards go bad and after the replacement all was good again.. until the RocketRaid 2722 card and its obscure "Task File error" error message came up again.

Everything up to this point had been working smoothly since end of Sept 2015 after the rebuild. All disks are 2TB in size, partitioned via 'parted' with 0% and 100% used for partition boundaries on each drive. Everything had been working wonderfully long before but the array was taken out due to some issues I had with 3 hitachi drives that refused to work on the RR2722 card/drivers. Long story.

I've swapped out two drives in the array and no luck yet as it doesn't seem to be hardware failure related.. I've not had any signs of data corruption, just meta-data corruption/errors.

Quoted 7 lines

If I remember correct, the format applied to the array was done under 3.6.11 kernel as
I'm still going through the same xfs_repair as above to get the array to mount. It keeps failing after it tries to format the log to cycle 67.

I'll see if I can get you an strace of things.

FWIW, I created an md array of similar geometry and ran through some fsstress/xfs_repair sequences just to see if there was anything obviously broken in the stack here, but I don't hit any issues. xfs_repair can zero the log and reformat it successfully. This is on a 4.6.0-rc1 kernel.

So I think the big question here is why are these certain I/Os failing? This might ultimately require investigation at the md layer and/or further down to your storage controller driver, etc. Anyways, here's the first failed I/O from strace_2.1.txt:

02:34:36.309704 pread64(4, 0x7fe772ec0200, 2097152, 3001552175104) = -1 EIO (Input/output error)

That's a 2MB read during phase 2, which is probably what leads to the "failed to find log head" error. The read offset is right around the middle of the array where the internal log resides. What's also interesting is that it is preceded by a bunch of other read I/Os that all appear to complete fine, but those are all 512b I/Os.

What happens if you manually issue the read call that failed? E.g., umount the filesystem and run the following command directly against the array:

Checking the drives with smartctl shows no errors nor does 'dmesg' show any hardware i/o or controller related errors...

I've tried scrubbing the array and no bad sectors are found either..

I'm running kernel 3.19.8 with xfsprogs 4.5.

Hello,

I have an mdadm array with a xfs v5 filesystem on it and its begun to give
me issues when trying to mount it as well as complete xfs_repair. Not sure
if anyone might be able to shed some light on what is going on or how to
correct the issue?

Quoted 9 lines

When I try and mount the fs, it complains with:

[  388.479847] XFS (md2): Mounting V5 Filesystem
[  388.494686] XFS (md2): metadata I/O error: block 0x15d6d39c0

[  388.495013] XFS (md2): failed to find log head
[  388.495018] XFS (md2): log mount/recovery failed: error -5
[  388.495090] XFS (md2): log mount failed

So a read I/O error from the kernel...

Quoted 13 lines

This is where its not making any sense for me, If I try and run "xfs_repair
/dev/md2" it fails with:

Phase 1 - find and verify superblock...
- reporting progress in intervals of 15 minutes
Phase 2 - using internal log
- zero log...
xfs_repair: read failed: Input/output error failed to find log head
zero_log: cannot find log head/tail (xlog_find_tail=-5)

Quoted 7 lines

fatal error -- ERROR: The log head and/or tail cannot be discovered. Attempt
to mount the
filesystem to replay the log or use the -L option to destroy the log and
attempt a repair.

... similar read error from xfsprogs...

Quoted 12 lines

But if I run "xfs_repair -L /dev/md2" which gives:

Phase 1 - find and verify superblock...
- reporting progress in intervals of 15 minutes
Phase 2 - using internal log
- zero log...
xfs_repair: read failed: Input/output error
failed to find log head
zero_log: cannot find log head/tail (xlog_find_tail=-5)
xfs_repair: libxfs_device_zero write failed: Input/output error

... and it looks like it fails to write as well when trying to zero the log...

Quoted 12 lines

then try and re-run "xfs_repair /dev/md2" it starts traversing the filesystem all the way to "Phase 7" then errors with:

Phase 7 - verify and correct link counts...
- 14:36:55: verify and correct link counts - 33 of 33
allocation
groups done
Maximum metadata LSN (64:2230592) is ahead of log (0:0). Format log to cycle 67.
xfs_repair: libxfs_device_zero write failed: Input/output error

Quoted 2 lines

Yet at this point I can now mount the filesystem..

... and this is effectively a repeat of the write error as we try to format the log with a correct LSN based on the metadata LSN tracked by the repair process. Your kernel is old enough that runtime probably won't complain either way (note that 3.19 might be considered a fairly early kernel for using CRC support). Perhaps the first write attempt zeroed enough of the log before it failed that log recovery wasn't required, and thus these problematic I/Os were avoided.

What's the history of this fs? Has it been working for some time, just recently formatted? What lead to the need for log recovery? What's the mdadm --detail info, member device size, total array size, xfs_info of the filesystem, etc..?

Quoted 7 lines

Does xfs_repair run clean at this point? If so, does 'xfs_repair -L' still reproduce the write error (note that I'm assuming you have a clean
log such that this command will not cause data loss). If so, an strace of the repair process might be interesting...

Brian

The filesystem is about a year old as I had one of the Addonics backplane
boards go bad and after the replacement all was good again.. until the RocketRaid 2722 card and its obscure "Task File error" error message came up
again.

Everything up to this point had been working smoothly since end of Sept 2015
after the rebuild. All disks are 2TB in size, partitioned via 'parted' with
0% and 100% used for partition boundaries on each drive. Everything had been
working wonderfully long before but the array was taken out due to some issues I had with 3 hitachi drives that refused to work on the RR2722 card/drivers. Long story.

I've swapped out two drives in the array and no luck yet as it doesn't seem
to be hardware failure related.. I've not had any signs of data corruption,
just meta-data corruption/errors.

Quoted 8 lines

If I remember correct, the format applied to the array was done under 3.6.11
kernel as
I'm still going through the same xfs_repair as above to get the array to mount. It keeps failing after it tries to format the log to cycle 67.

I'll see if I can get you an strace of things.

FWIW, I created an md array of similar geometry and ran through some fsstress/xfs_repair sequences just to see if there was anything obviously broken in the stack here, but I don't hit any issues. xfs_repair can zero the log and reformat it successfully. This is on a 4.6.0-rc1 kernel.

So I think the big question here is why are these certain I/Os failing? This might ultimately require investigation at the md layer and/or further down to your storage controller driver, etc. Anyways, here's the first failed I/O from strace_2.1.txt:

02:34:36.309704 pread64(4, 0x7fe772ec0200, 2097152, 3001552175104) = -1 EIO (Input/output error)

That's a 2MB read during phase 2, which is probably what leads to the "failed to find log head" error. The read offset is right around the middle of the array where the internal log resides. What's also interesting is that it is preceded by a bunch of other read I/Os that all appear to complete fine, but those are all 512b I/Os.

Quoted 7 lines

What happens if you manually issue the read call that failed? E.g., umount the filesystem and run the following command directly against the array:

xfs_io -dc "pread 3001552175104 2097152" /dev/md2

Brian

It failed with the same error. I've attached the strace output for the command.

The array is fairly full so I'm wondering if something is out of alignment somewhere thats causing this?

/dev/md2 5858060288 5245630392 612429896 90% /mnt/md2

When I had the array plugged into another controller which isn't a rocketraid card, it did complain about all the drives not being aligned properly? Somehow it looks like sdk wasn't partitioned the same as the rest, I'm wondering if thats screwing things up?

Checking the drives with smartctl shows no errors nor does 'dmesg' show any
hardware i/o or controller related errors...

I've tried scrubbing the array and no bad sectors are found either..

I'm running kernel 3.19.8 with xfsprogs 4.5.

so offset is 3001552175104, or roughly around the 3TB mark. Given the log i always placed int eh middle of the filesystem and you have a 6TB device, then the above definitely looks like a valid place to be reading from the log.

xfs_logprint:

     data device: 0x902
     log device: 0x902 daddr: 5860130880 length: 4173824

daddr converted to offset is 5860130880 * 512 = 3001552175104, which tells us that the above pread64 failure was definitely coming from an attempt to read the log.

That this is coming from the block device from userspace indicates a problem below XFS. There is something going wrong with your underlying block device and/or hardware here; AFAICT it's not related to XFS at all.

Compared to the other devices, it has a different start sector, a different size, and an msdos partition table rather than gpt. Definitely a red flag...

Reported physical IO errors to a write command. Really, this looks like a hardware issue, not something that can be fixed by running xfs_repair...

Cheers,

Dave.

Sorry to dig up old stuff here but after replacing hardware and pulling my hair out to no end, I traced the source of the problem out.

On every drive in the array, the points on the PCB which the contacts for the drives motors and head/actuators make contact with were oxidized enough to cause the issue. I ended up pulling the PCB off each drive and cleaning them as well as cleaning out all other cable and drive connectors from the HBA outward and everything is happy again.

No. I'm up in NW Ontario in Canada actually, far away from any salt water. I'm guessing it was from the combination of air pollutants/humidity and heat given the drives are not in the most hospitable environment esp during the summer ... but after cleaning the board contacts up as well as the esata cable ends/ports, its working great again.

I'm beginning to think when I do replace any drives, after warranty is up on them, pull off the PCB, clean it up and coat the contacts with a good smearing of dielectric grease to keep the issue from happening.

Makes me wonder how many other people out there suffer from the same issue given the amount of unresolved similar hw errors I've found while googling the errors..

Thanks again,
Andrew

What happens if you manually issue the read call that failed? E.g., umount the filesystem and run the following command directly against the array:

xfs_io -dc "pread 3001552175104 2097152" /dev/md2

Brian

It failed with the same error. I've attached the strace output for the command.

The array is fairly full so I'm wondering if something is out of alignment somewhere thats causing this?

/dev/md2 5858060288 5245630392 612429896 90% /mnt/md2

When I had the array plugged into another controller which isn't a rocketraid card, it did complain about all the drives not being aligned properly? Somehow it looks like sdk wasn't partitioned the same as the rest, I'm wondering if thats screwing things up?

What happens if you manually issue the read call that failed? E.g., umount the filesystem and run the following command directly against the array:

xfs_io -dc "pread 3001552175104 2097152" /dev/md2

Brian

It failed with the same error. I've attached the strace output for the command.

Thanks, well that is interesting. The larger 2MB read eventually results in this smaller (4k) read that fails:

16:02:14.221784 pread64(3, 0x1ce7000, 4096, 3001553125376) = -1 EIO (Input/output error)

So you could repeat that command with offset 3001553125376 and size 4k and just confirm that still fails. As Dave points out, something is wrong with the storage here and that is what needs to be resolved.

With regard to the xfs_repair behavior... you're initially hitting a read error when the filesystem scans through the log looking for the head and tail to determine whether the log is dirty. If the log is zeroed, this sequence can be bypassed and the log assumed clean. I suspect by zeroing enough of the log before it fails, your repair sequence is just bypassing the log head/tail discovery that previously scanned areas of the disk that are having issues. In other words, it's just temporarily stepping around the problem until the log progresses back to this address range.

What you probably have to do at this point is use the simple I/O error reproducer you have to try and determine why the storage returns an error. It could be anywhere from something broken in the md subsystem, to the controller driver, to a physical problem with the associated disk. I'd suggest to start by reporting to the md mailing list and work down from there...

The array is fairly full so I'm wondering if something is out of alignment somewhere thats causing this?

/dev/md2 5858060288 5245630392 612429896 90% /mnt/md2

When I had the array plugged into another controller which isn't a rocketraid card, it did complain about all the drives not being aligned properly? Somehow it looks like sdk wasn't partitioned the same as the rest, I'm wondering if thats screwing things up?

Checking the drives with smartctl shows no errors nor does 'dmesg' show any hardware i/o or controller related errors...

I've tried scrubbing the array and no bad sectors are found either..

I'm running kernel 3.19.8 with xfsprogs 4.5.

That seems to make sense. I've started a check of the array and see what happens. I don't believe its a hardware error as neither sata pmp controller I have it on logs any hardware/cabling related errors at all.

Thanks for the help so far. I'll let you know how I make out if I ever figure out where the gremlins are hiding..

What happens if you manually issue the read call that failed? E.g., umount the filesystem and run the following command directly against the
array:

xfs_io -dc "pread 3001552175104 2097152" /dev/md2

It failed with the same error. I've attached the strace output for the command.

Thanks, well that is interesting. The larger 2MB read eventually results in this smaller (4k) read that fails:

16:02:14.221784 pread64(3, 0x1ce7000, 4096, 3001553125376) = -1 EIO (Input/output error)

So you could repeat that command with offset 3001553125376 and size 4k and just confirm that still fails. As Dave points out, something is wrong with the storage here and that is what needs to be resolved.

With regard to the xfs_repair behavior... you're initially hitting a read error when the filesystem scans through the log looking for the head and tail to determine whether the log is dirty. If the log is zeroed, this sequence can be bypassed and the log assumed clean. I suspect by zeroing enough of the log before it fails, your repair sequence is just bypassing the log head/tail discovery that previously scanned areas of the disk that are having issues. In other words, it's just temporarily stepping around the problem until the log progresses back to this address range.

What you probably have to do at this point is use the simple I/O error reproducer you have to try and determine why the storage returns an error. It could be anywhere from something broken in the md subsystem, to the controller driver, to a physical problem with the associated disk. I'd suggest to start by reporting to the md mailing list and work down from there...

The array is fairly full so I'm wondering if something is out of alignment
somewhere thats causing this?

/dev/md2 5858060288 5245630392 612429896 90% /mnt/md2

When I had the array plugged into another controller which isn't a rocketraid card, it did complain about all the drives not being aligned properly? Somehow it looks like sdk wasn't partitioned the same as the rest,
I'm wondering if thats screwing things up?

That seems to make sense. I've started a check of the array and see what happens. I don't believe its a hardware error as neither sata pmp controller I have it on logs any hardware/cabling related errors at all.

Thanks for the help so far. I'll let you know how I make out if I ever figure out where the gremlins are hiding..

What happens if you manually issue the read call that failed? E.g., umount the filesystem and run the following command directly against the
array:

xfs_io -dc "pread 3001552175104 2097152" /dev/md2

It failed with the same error. I've attached the strace output for the command.

Thanks, well that is interesting. The larger 2MB read eventually results in this smaller (4k) read that fails:

16:02:14.221784 pread64(3, 0x1ce7000, 4096, 3001553125376) = -1 EIO (Input/output error)

So you could repeat that command with offset 3001553125376 and size 4k and just confirm that still fails. As Dave points out, something is wrong with the storage here and that is what needs to be resolved.

With regard to the xfs_repair behavior... you're initially hitting a read error when the filesystem scans through the log looking for the head and tail to determine whether the log is dirty. If the log is zeroed, this sequence can be bypassed and the log assumed clean. I suspect by zeroing enough of the log before it fails, your repair sequence is just bypassing the log head/tail discovery that previously scanned areas of the disk that are having issues. In other words, it's just temporarily stepping around the problem until the log progresses back to this address range.

What you probably have to do at this point is use the simple I/O error reproducer you have to try and determine why the storage returns an error. It could be anywhere from something broken in the md subsystem, to the controller driver, to a physical problem with the associated disk. I'd suggest to start by reporting to the md mailing list and work down from there...

The array is fairly full so I'm wondering if something is out of alignment
somewhere thats causing this?

/dev/md2 5858060288 5245630392 612429896 90% /mnt/md2

When I had the array plugged into another controller which isn't a rocketraid card, it did complain about all the drives not being aligned properly? Somehow it looks like sdk wasn't partitioned the same as the rest,
I'm wondering if thats screwing things up?

I'm running kernel 3.19.8 with xfsprogs 4.5.

What happens if you manually issue the read call that failed? E.g., umount the filesystem and run the following command directly against the array:

xfs_io -dc "pread 3001552175104 2097152" /dev/md2

Brian

It failed with the same error. I've attached the strace output for the command.

Thanks, well that is interesting. The larger 2MB read eventually results in this smaller (4k) read that fails:

16:02:14.221784 pread64(3, 0x1ce7000, 4096, 3001553125376) = -1 EIO (Input/output error)

So you could repeat that command with offset 3001553125376 and size 4k and just confirm that still fails. As Dave points out, something is wrong with the storage here and that is what needs to be resolved.

With regard to the xfs_repair behavior... you're initially hitting a read error when the filesystem scans through the log looking for the head and tail to determine whether the log is dirty. If the log is zeroed, this sequence can be bypassed and the log assumed clean. I suspect by zeroing enough of the log before it fails, your repair sequence is just bypassing the log head/tail discovery that previously scanned areas of the disk that are having issues. In other words, it's just temporarily stepping around the problem until the log progresses back to this address range.

What you probably have to do at this point is use the simple I/O error reproducer you have to try and determine why the storage returns an error. It could be anywhere from something broken in the md subsystem, to the controller driver, to a physical problem with the associated disk. I'd suggest to start by reporting to the md mailing list and work down from there...

The array is fairly full so I'm wondering if something is out of alignment somewhere thats causing this?

/dev/md2 5858060288 5245630392 612429896 90% /mnt/md2

When I had the array plugged into another controller which isn't a rocketraid card, it did complain about all the drives not being aligned properly? Somehow it looks like sdk wasn't partitioned the same as the rest, I'm wondering if thats screwing things up?

Checking the drives with smartctl shows no errors nor does 'dmesg' show any hardware i/o or controller related errors...

I've tried scrubbing the array and no bad sectors are found either..

I'm running kernel 3.19.8 with xfsprogs 4.5.
