fsck and 0 in /etc/fstab

[Charles T Fischer]

if a mounted filesystem crashes, and it has 0 in the fstab column for fsck, does that mean it will not fsck the filesystem on boot? or does the 0 merely mean under normal operating/boot conditions it will not fsck?

[Jeff_Traigle]

According to the fstab man page:

A file system with a pass number of zero is ignored by the fsck command.

Therefore, regardless of it's state, it would not be checked or corrected at boot time.

[A. Clay Stephenson]

You should man fstab for the answer. In any event, a pass number of 0 is ignored by fsck on boot. You can, of course, manually fsck the filesystem regardless of the pass number value in fstab corresponding to that filesystem.

Thanks for the fast reply to you both, i had read the man page, just was hoping that was under normal conditions. Thanks to you both
