Yeah, I've had this thought. I do this even on 1TB ext3 file systems,
just so I don't get caught in the awkward, "yeah it will be up in 15
minutes" which turns into 2 hours situation.
However, is it really safe to never do an fsck? It seems that most of
the time it's unnecessary for ext3 as the journal recovery usually works
fine.
The tune2fs man page also states this, which I could just ignore, but
makes me feel slightly uneasy:
You should strongly consider the consequences of disabling
mount-count-dependent checking entirely. Bad disk
drives,
cables, memory, and kernel bugs could all corrupt a
filesystem
without marking the filesystem dirty or in error. If
you are
using journaling on your filesystem, your filesystem
will never
be marked dirty, so it will not normally be checked. A
filesysâ
tem error detected by the kernel will still force an fsck
on the
next reboot, but it may already be too late to prevent
data loss
at that point.
Perhaps the right answer is to do regular maintenance once or twice a
year on these huge filesystems. In most cases I can find 8hours or more
to schedule an fsck on a Friday night...
