Hello everyone,
Our Amanda backup servers use JFS on ~2TB RAID arrays as virtual tape
archive space. Under normal circumstances, the setup works great.
However, twice in the last six months or so, the filesystems have been
uncleanly unmounted. Once due to a kernel crash when the FC storage
array was accidently disconnected, and once this weekend for an
as-of-yet unknown reason.
When this happens, the filesystem is left in an unmountable state.
Mount responds that jfs couldn't find a valid superblock. A simple
fsck fixes the issue in less than 60 seconds. There's never been any
data loss as a result of this.
But it's a bad situation - our backups failed the last two nights
after the filesystem was unmountable.
We're using RH Enterprise Linux 3 on the JFS boxes with kernel 2.4.21-37.ELsmp
and jfsutils-1.1.2-2. Any ideas on what we can do to prevent needing
this fsck?
