That's a pretty standard message. The dmesg|tail says

[ 4475.435209] XFS (dm-20): Mounting V5 Filesystem [ 4475.489498] XFS (dm-20): Corruption warning: Metadata has LSN (1:5500) ahead of current LSN (1:2). Please unmount and run xfs_repair (>= v4.3) to resolve. [ 4475.489503] XFS (dm-20): log mount/recovery failed: error -22 [ 4475.489537] XFS (dm-20): log mount failed

Iterating xfs_repair & mount is of no joy.

I'd chose XFS on advice here to deal with big files, aka movies. I'm not happy with the result I've ended up with.

Is there anyone more knowledgeable about XFS recovery?

There are loads of people extremely knowledgeable about it on the XFS mailing list. I suggest trying there. FWIW I haven't had any problems with XFS in years and years of using it, so hopefully they'll get to the bottom of the problem.

The XFS list will want a good report and the above is missing some information: http://xfs.org/index.php/XFS_FAQ#Q:_What_information_should_I_include_when_r... In addition to that, they will want to see the kernel messages leading up to the problem. I would find the boot where things were working and then went bad, and include that entire boot, filtered for kernel messages: journalctl -b -1 (or -2, -3) will get you previous boots. And filter with -k like this journalctl -b -1 -k > kernel.log And include that file as an attachment. The first traces are at least as important as the most recent. Don't think it's helpful to trim it, often the actual instigator is before the file system starts complaining, so include the whole thing. Next, what was done to the file system following the problem. Reboot? xfs_repair? mount? Be specific. XFS doesn't like having xfs_repair run on it right away after a reboot, it wants to just be mounted. And also provide a complete history of "iterating xfs_repair & mount" with all of the messages. The more information provided, the better the chance of recovery. Also include what this file system is built on top of. I see XFS (dm-20) so that suggests it's on LVM or maybe dmcrypt. -- Chris Murphy -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
