last xfs_repair time?
Hi folks,
Is it possible to query XFS for the last time xfs_repair fixed a filesystem? I've been searching the man pages and haven't found anything useful.
thanks!

Not that I know of.
Barry is the repair maintainer/expert though.

AFAIK it doesn't, but that'd be a neat feature - adding space for that, and maybe date of mkfs (or mkfs version) etc might be nice too.
Thanks for the responses! It's handy to have that information available, especially when you're maintaining hundreds of workstations whose power cables occasionally get yanked out by their users. :/
Here's what we can get from ext3:
% sudo dumpe2fs -h /dev/sda1 | grep 2008
dumpe2fs 1.40.8 (13-Mar-2008)
Inodes per group: 2008
Filesystem created: Thu May 29 11:11:12 2008
Last mount time: Tue Sep 30 18:01:18 2008
Last write time: Tue Sep 30 18:01:18 2008
Last checked: Thu May 29 11:11:12 2008cheers,

So, for what it's worth, power loss should not necessarily require a repair; as long as you have barriers enabled and/or you're not losing log writes to a volatile write cache, power loss should never corrupt the filesystem metadata; that is what the log is for, after all...

That would sort of fall under the last repair logs still on the todo list.

Our disks are partitioned with LVM, so we don't have write barriers. We just recently disabled write caching, though, so our future should be brighter than it's been. :)

Hi!
Lets see whether MailMan lets GPG signature unmangled or whether it is something else that mangles it.

I really hope that LVM gets write barrier support for write barrier capable targets. Unless it does my notebook will use plain partitions for anything but testing filesystems. Otherwise with 2.6.16 back then I hardly felt a difference in XFS speed after turning off write caches.
