xfsdump INTERRUPT issue

I'm trying to prepare a question regarding an xfsdump INTERRUPT error I'm getting, and I'm trying to follow the guidelines for reporting such issues here:

http://xfs.org/index.php/XFS_FAQ#Q:_What_information_should_I_include_when_r
eporting_a_problem.3F

But these last two instructions I'm having a problem finding the information on how to generate:

xfs_info output on the filesystem in question (I tried xfs_info /dev/sdc, but it keeps saying for each drive that it's not a mounted xfs system IIRC)

dmesg output showing all error messages and stack traces

Then you need to describe your workload that is causing the problem, and a demonstration of the bad behavior that is occurring. If it is a performance problem, then 30s - 1 minute samples of:
1. iostat -x -d -m 5
2. vmstat 5

Do I run this simultaneously while xfstools are working? I'm also not sure what's meant by describe your workload. Can someone step me through this?

Please excuse my n00bness.

Best,
Jeffrey

Anyone?

Or do I have enough to ask the question?

We aren't the US Govt, i.e. we're not going to ignore your help request just because you're missing a few details. They may not be relevant anyway. So ask away with the details you do have. If anything else is needed we'll ask you to provide it.

$ man xfs_info
....
	xfs_info [ -t mtab ] mount-point
....

Run the dmesg command....

Do you have a performance problem? I don't think you have - your problem is that xfsdump is failing for some reason - so this information is unnecessary.

As to your workload, your problem is xfsdump is failing for some reason. Hence we need to know roughly what xfsdump is running on. i.e. describe the directory structure/filesystem contents being backed up....

BTW, don't expect responses to questions in a hour late on friday night/weekends - if you are lucky someone will be in front of their computer over a weekend, sometimes you are not so lucky...

Cheers,

Dave.

Ah :)

Ok, I'll skip dmesg and add xfs_info. And I'll make sure to post everything Monday.

Thanks again :)

Best,
J.

Thank you to Stan and Dave for helping me through this.

Ok, here's the file, printed below.

Basically, I'm running the following commands under Ubuntu 12.10:

Type mkdir /mnt/fp
Type mkdir /mnt/hr20
Type mount -t xfs -o rtdev=/dev/sda3 /dev/sda2 /mnt/fp Type mount -t xfs -o rtdev=/dev/sdb3 /dev/sdb2 /mnt/hr20 Type xfsdump -J - /mnt/hr20 | xfsrestore -J - /mnt/fp

When run, I get this as my output:

xfsdump: WARNING: write to stdio failed: 32 (Broken pipe)
xfsdump: ending media file
xfsdump: media file size 18874368 bytes
xfsdump: dump size (non-dir files) : 13698056 bytes
xfsdump: NOTE: dump interrupted: 16 seconds elapsed
xfsdump: Dump Status: INTERRUPT

This happens each time. In the forum where this copy procedure was suggested, they've been reporting that the latest xfsprogs is creating these errors, which didn't happen under at least somewhat earlier versions.

The version of xfsprogs should be in the file, but it was just downloaded a few days ago using git.

Best,
Jeffrey

FWIW, this implies that xfsrestore failed. What is the output from xfsrestore? Can you just run xfsdump to a file?

Also, the dmesg output is missing - can you attach it?

Cheers,

Dave.

Hi, Dave & Stan, et al--

Are you guys getting this post? I don't see it showing up on the list and have had no responses. I'm wondering if the size of the text of the requested xfs info I had added is causing an issue getting it posted.

If not, here's a repost, using a link to the file instead.

You need to acclimate yourself to the environment/culture of FLOSS mailing lists. First, don't be giddy. Responses to users will rarely be immediate. People, both devs and fellow users, contribute help on an "as time permits" basis. You are not paying for support here. I've seen some msgs go unanswered for a week or more, both initial requests and follow ups. I short, don't expect rapid responses and individual hand holding.

Regarding what you think may be lost mail, using an office document format is not wise, though I don't know if it's allowed here or not. In general, with FLOSS lists, use plain text, always, whether inline or attachment. Try not to reference external links as this list is archived by many sites. Get it all in the archives.

Finally, if you sent me a direct email and my server rejected it you would receive an NDR pretty quickly. And I don't see any msgs from you in my spam tagged folder.

Stan

Hi, Stan--

Ah, sorry.

I actually tried sending it to you, Dave and the list by attachment and by including the text in the email. So it looks like this is the only way it got through. Should I try reposting a version with just the text again?

Best,
J.

xfs_info output and this below is all that is needed at this point.

The command you posted

xfsdump -J - /mnt/hr20 | xfsrestore -J - /mnt/fp

pipes the output from xfsdump into xfsrestore. This error

xfsdump: WARNING: write to stdio failed: 32 (Broken pipe)

tells us something broke while piping into xfsrestore, possibly xfsrestore itself. I believe what Dave is asking you is to xfsdump to a file, then xfsrestore that file. In two separate operations. This should tell us more about where the problem is.

Regarding dmesg information, simply do

~$ dmesg

and copy the output into your email. It should be a few screen fulls starting with something like:

Hi, Stan--

Ok, I truly apologize for my ignorance, but I don't know how to dump the contents to a file. Is it something like:

xfsdump -J - somefile_xfsdump.txt
xfsrestore -J - somefile_xfsrestore.txt

?

Best,
J.

~$ man xfsdump

Look at option "-f".

~$ man xfsrestore

See options "-f" "-t" and "-v".

The point of this exercise I believe is to see what errors are thrown by xfsdump or xfsrestore when they are executed independently, vs through a pipe. Do note that this may not be the final step in testing before you have an answer. Post any errors or informational output that results from these commands.

Note that the file written by xfsdump is going to be about the same size as the filesystem being dumped. I.e. if the filesystem being dumped is 1TB then you need 1TB of free space on the device where the target directory resides--you're dumping an entire XFS filesystem into a single file. Also, be sure to use "-t" so xfsrestore doesn't actually write anything. Did you read "-v"?

No, please don't. Everything you have sent has got through.

If you really, want to know if something got through to the list, go an look at the list archives on one of the many list archive sites availble. e.g. here's the entire thread:
