How to disable auto FSCK

(1) open /etc/fstab

nano /etc/fstab

(2) edit the line that contains the filesystem and modify the last number in the row to ‘0’, which disables fsck.

/dev/VolGroup/LogVol     /mountpoint      defaults    1 0

(3) Save it, done.

Note: Will not typically suggest disabling the on-boot fsck except in situations where the machine does not boot, the file system is extremely large, or the file system is on remote storage.
