There was a great idea mentioned by Theo T'so on l-k a while ago
- note the time and take a snapshot of an online fs.
- fsck the snapshot
if the snapshot is clean:
- use tune2fs to update the last time-last-checked field of the FS
with the noted time. (and/or reset the mounts-since-last-checked
count, if you use mount-count checks)
- You have a problem :)
No more 'quick' reboots only to encounter "128 days since last check,
forcing fsck" messages and have to wait..
Course, LVM2 snapshots werent particularly stable last time i tried
using them (good while ago)...
