(1) open /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.
