Comment 0 for bug 692848

On our Ubuntu 10.04 LTS server running x86 code, this evening a kernel update was ready for installation. I updated the kernel, rebooted (IPL'ed), and proceeded with the backup which utilized xfsdump as we use the xfs filesystem. Four of the xfsdump received a never before seen error: SGI_FS_BULKSTAT errno = 22

Output as follows:
using file dump (drive_simple) strategy
version 3.0.4 (dump format 3.0) - Running single-threaded
level 0 dump of ldslnx01:/srv

This backup file did have some size to it. The other three, backing up smaller amounts of data, were all zero (0) length dump files.

I rebooted to the prior kernel: $ uname -a
Linux ldslnx01 2.6.32-26-generic-pae #48-Ubuntu SMP Wed Nov 24 10:31:20 UTC 2010 i686 GNU/Linux

And the same backup gets to 100% success.

Reboot to the new kernel, same failure.

I think that fairly well illustrates that the problem exists only with the kernel update installed this evening.

I did come across a reference to this problem on the SGI website:

http://techpubs.sgi.com/library/tpl/cgi-bin/getdoc.cgi?coll=0650&db=relnotes&fname=/usr/relnotes/eoe
  1.6.17 Bugs fixed in IRIX 6.5.13
    + 816457: xfsdump SGI_FS_BULKSTAT errno = 22 cxfs

So evidently it is something that has been seen and corrected in IRIX.
