/dev/sda6 - is 100GB XFS partition. The filesystem contains only data. It happened this night where only some cronjobs were running...


umounting results in the following /var/log/messages entry

I tried to mount it again - but again kernel ooops again

Reproducible: Didn't try
Comment 1 Jochen Schlick 2010-04-14 19:45:22 UTC 
only xfs_repair -L /dev/sda6 helped.
Comment 2 Mike Pagano gentoo-dev 2010-04-15 16:58:38 UTC 
Still an issue?
Comment 3 Jochen Schlick 2010-04-15 21:05:42 UTC 
no - except that I got some files in lost+found of the xfs-partition. 
The data itself on the corrupted partition was not so important - one fedora and 2 opensuse kvm guests. After the repair I checked also the filesystems of these virtual machines and everything was ok.

But I found it worth to mention - because this xfs-filesystem corruption happened during the night at 3o clock where only some cronjobs were running (far less than normal load during the day and there was no power failure, no info from smartd, and nothing in particular in /var/log/messages except the xfs error...
Comment 4 Mike Pagano gentoo-dev 2010-04-21 23:42:34 UTC 
ok, feel free to reopen if this error reoccurs.
