What is the meaning of each column in /etc/fstab file ?




Following is a sample /etc/fstab entry:

--------------------------------------------------------------------
/dev/sdb1           /disk          ext3        defaults     0   0
---------------------------------------------------------------------

There are six fields in /etc/fstab file.,the columns are as follows:

1. The device name or other means of locating the partition or data source.
2. The mount point, where the data is to be attached to the filesystem.
3. The filesystem type.
4. Mount options .
5. dump-freq adjusts the archiving schedule for the partition (used by dump).
6. pass-num Controls the order in which fsck checks the device/partition for errors at boot time.

The root device should be 1. Other partitions should 2 or 0 to disable checking. A value of zero in either of the last 2 columns disables the corresponding feature.
