2.4.22-pre3 and reiserfs boot problem

Hello,

I just tried 2.4.22-pre3 and found out I cannot boot my test box any more. It halts at:

reiserfs: found format "3.6" with standard journal

on a partition located on aic7xxx based hd.

Booting the box with pre2 works perfectly well. Anything I should try? What information is needed?

Same config here (reiserfs 3.6.x, aic7xxx drive), works without problems. Is reiserfs or aic7xxx compiled as a module in your setup? If so did you remember to install the new modules and mkinitrd (if required).

Is reiserfs on your root drive? If not can you please boot into single user mode, enable sysrq, try the mount again and get the decoded output from sysrq-p and sysrq-t if it hangs.

Hello Chris,

I tried to produce some useful output but failed. Additionals I found:

- pre3-ac1 has the same problem
- the box _hangs_ in fact, no sysrq is working.
(you need hw-reset to revive the box)
- I can see no disk activity on the 3ware RAID in question
- It always shows up, completely reproducable
- It shows during boot and during single- or multiuser (mount from console)

Step one is to figure out if the problem is reiserfs or 3ware. Instead of mounting the filesystem, run debugreiserfs -d /dev/xxxx > /dev/null and see if you still hang.
This will read the FS metadata and should generate enough io to trigger the hang if it is a 3ware problem.

This complete hang is _very_ suspicious. Usually you cannot achieve such results without touching hardware.

Or if this one suceeds, then may be reiserfsck --check /dev/xxxx to get journal replayed. This is in case access pattern matters.

Ok, I tried this. debugreiserfs runs without any problems. Disks show quite an activity, the whole thing lasts 1-2 minutes.
mount afterwards shows the same hang.

I can try that, too. What do you expect to see?

Well, it will either hang or not, I think.
It it won't hang, this will complicate matters.
Then next step would be probably to try and mount the partition from usermodelinux if you are able to conduct such a test.
I am still pretty skeptical about the possibility that recent reiserfs changes broke stuff.

ok, I did the reiserfsck and it works flawlessly. No errors no problems no hang.
I tried mount afterwards and it still hangs.
Is there some recent change around the mount procedure itself? maybe it is really unrelated to reiserfs and 3ware...

Stephan

PS to Marcelo:
There is a problem with 2.4.22-pre3. I cannot mount a reiserfs data-partition with 320 GB size located on a 3ware RAID. It just hangs the box, during init or any runlevel I tried. It is completely reproducable, but debugreiserfs on the partition and reiserfsck both show no problems at all ...
The things mounts flawlessly under 2.4.22-pre2 and below.

There are no 3ware changes in pre3. So it must be reiserfs or something else. Lets try reverting the reiserfs patches to see if they are the cause?

Attached are files rei1, rei2, and rei3 (all gzip compressed).

I reverted all three patches and the problem stays just the same. I guess this makes it a lot likely that the problem lies elsewhere.

If you want me to try others, just send them to me like these three.

Stephan,

First of all, thanks a lot for your help. Not everyone is willing to debug/test problems like you do. This is very important for us.

Well, we now know reiserfs patches in 2.4.22-pre are not the problem.

2.4.21 is OK (does not crash when mounting) correct?

Can you please revert them (with patch -R) and try to reproduce the problem?

Thanks

Is it just this partition or any reiserfs fs on 3ware?

It it possible to mount raw partitions with UML?

Which mainboard do you use ?
I'm having endless pain with a 3ware raid and Tyan mainboards, so much I really really want to replace it with anything else that is stable (probably a single Intel P4).
