Re: Keep auto-periodic fsck's enabled on ext3 partitions?
Thanks for weighing in with your opinion, which was basically what I
was planning to do anyways unless I heard otherwise. We don't run
cutting-edge kernels, only upgrading for important bug or security
patches. Combined with nightly backups of customer data, I think we'll
be pretty safe disabling auto-fscks (knock on wood).

fscks of partitions after a certain number of mounts, or after a
certain period of time since the last fsck (6 months in our case). My
question is, is it detrimental to disable these auto-checks and not
If you always upgrade to the latest kernel when it's out, it's probably
a good idea to leave it on; otherwise, and as long as you don't
experience problems, I suggest to switch it off.
The man page for tune2fs says it's not wise...
That is mostly relevant for systems that don't take regular backups. If
you do (and for the sake of your customers, I hope that is the case),
the extra precaution isn't really necessary, and probably a bad idea if
the cost involved (in terms of downtime) is too high.
The idea of the fsck is so that you would notice if anything out of the
ordinary is going on in the kernel. If you are, however, running the
same kernel all the time, either nothing will happen (and the fsck's
superfluous), or your kernel is broken and you'll be fucked anyway (and
the fsck's won't help you).
