Hi list,
I recently I had a failed disk in a raid6 setup, which resulted in an IO
error, which in turn caused XFS to shut down with the messages below.
I've seen on this list that incorrect use of xfs_repair might damage the fs
even more, so I would like to ask for some advice on the best way to
proceed.
Currently I have unmounted the filesystem, replaced the failed disk and
rebuilt the raid array. I am upgrading xfstools to their latest version (the
current version is 2.9.8). Any hints on how to continue would be highly
appreciated.
Background: This is a Fedora Core 3 machine, with a vanilla 2.6.31 kernel.
The raid setup consists of 24x2TB disks in a raid6 setup. We use it to store
our backup snapshots and the entire volume is written to tape once a week.
Thanks in advance,
roel
