The /etc/fstab
file contains the file system
mount table, and provides all the information that the
mount command needs to mount block devices or
to implement binding of mounts. If you add a file system, create
the appropriate entry in /etc/fstab
to ensure
that the file system is mounted at boot time. The following are
sample entries from /etc/fstab
:
/dev/sda1 /boot ext4 defaults 1 2 /dev/sda2 / ext4 defaults 1 1 /dev/sda3 swap swap defaults 0 0
The first field is the device to mount specified by the device name, UUID, or device label, or the specification of a remote file system. A UUID or device label is preferable to a device name if the device name could change, for example:
LABEL=Projects /var/projects ext4 defaults 1 2
The second field is either the mount point for a file system or
swap
to indicate a swap partition.
The third field is the file system type, for example
ext4
or swap
.
The fourth field specifies any mount options.
The fifth column is used by the dump command. A value of 1 means dump the file system; 0 means the file system does not need to be dumped.
The sixth column is used by the file system checker, fsck, to determine in which order to perform file system checks at boot time. The value should be 1 for the root file system, 2 for other file systems. A value of 0 skips checking, as is appropriate for swap, file systems that are not mounted at boot time, or for binding of existing mounts.
For bind mounts, only the first four fields are specified, for example:
path
mount_point
none bind
The first field specifies the path of the file system, directory
hierarchy, or file that is to be mounted on the mount point
specified by the second field. The mount point must be a file if
the path specifies a file; otherwise, it must be a directory. The
third and fourth fields are specified as none
and bind
.
