Dear xfs developers
We have a SUN X4500 with 48 500 GB drives, that we configured under SUSE SLES
Among others, we have 3 RAID5 xfs filesystems, /dev/md4 with 20 units (9.27 TB)
/dev/md5 with 20 units (9.27 TB) and /dev/md6 with 5 units (1.95 TB)
These units are not backed up.
Due to a power shock, suddenly and without log messages about one half (5 TB) of the user
directories on /dev/md4 have disappeared.
I presume you mean after a reboot?
Upon reboot, /dev/md6 showed only 3 units, and after a xfs_repair it was again
/dev/md4 mounted immediately, but always with one half of the directories.
Were the lost directories recently created? I've never heard of
untouched, existing directories disappearing after a power loss...
WHat can I do? Any help would be appreciated, I would really be happy to
recover those files...
Not much to go on here I'm afraid. SLES10 is an old kernel, but it's
supported by SuSE at least.
