The location of the mount table is held in a file located in the following path: \u00ab\u00a0\/etc\/fstab\u00a0\u00bb. This file is generally maintained by the system administrator of the server. Each line within the file describes the device\/filesystems that are available to your system. Each field is separated by spaces or a tab. There are six fields for each entry:<\/p>\n
Field One:\u00a0<\/strong>Filesystem – This field describes the device or filesystem that is to be mounted. Ordinary mounts such as \u00ab\u00a0\/dev\/sdb1\u00a0\u00bb can be seen here. You may also come across NFS mounts. These are filesystems that are hosted by a remote server. These can be identified easily by the \u00ab\u00a0nfs\u00a0\u00bb<\/p>\n
\/rmtserver:\/opt\/test \/mynfs nfs ro,bg 0 0<\/p>\n
The above \u00ab\u00a0nfs\u00a0\u00bb example will mount \u00ab\u00a0\/opt\/test\u00a0\u00bb from the remote server \u00ab\u00a0rmtserver\u00a0\u00bb on the local mount point \u00ab\u00a0\/mynfs\u00a0\u00bb. This will be a read only mount. The \u00ab\u00a0bg\u00a0\u00bb specifies that it should be mounted as a background task.<\/p>\n
On many newer systems it is quite common to see devices specified by there \u00ab\u00a0UUID\u00a0\u00bb Universal Unique Identifier.<\/p>\n
Field Two:\u00a0<\/strong>Mount Point field. For a \u00ab\u00a0swap\u00a0\u00bb partition this field should be specified as \u00ab\u00a0none\u00a0\u00bb.<\/p>\n
Field Three:\u00a0<\/strong>This field describes the type of filesystem. Linux can support many different filesystems – \u00ab\u00a0ext2, ext3, ext4, hfs, iso9600, minix, msdos, nfs, ntfs, reiserfs, smbfs, vfat, xfs plus many more.\u00a0\u00bb For filesystems supported by the running kernel see \u00ab\u00a0\/proc\/filesystems\u00a0\u00bb.<\/p>\n
Field Four:\u00a0<\/strong>This field describes the mount options associated with the filesystem. This is a comma separated list. It should contain the type of mount plus any additional options.<\/p>\n
Basic Filesystem options:<\/strong><\/p>\n
defaults<\/strong>
\nUse default options: rw, suid, dev, exec, auto, nouser and async.<\/p>\n
auto<\/strong>
\nMount automatically at boot time.<\/p>\n
noauto<\/strong>
\nDo not mount automatically at boot time.<\/p>\n
user<\/strong>
\nAllow a normal user to mount.<\/p>\n
owner<\/strong>
\nAllow device owner to mount.<\/p>\n
comment<\/strong>
\nUsed by fstab maintaining programs.<\/p>\n
nofail<\/strong>
\nDo not report errors if this does not exist.<\/p>\n
Field Five:<\/strong>This field is used to identify which filesystems should by dumped by the \u00ab\u00a0dump\u00a0\u00bb command. A value of zero \u00ab\u00a00\u00a0\u00bb indicates that no dump is to take place.<\/p>\n
Field Six:<\/strong>This field is used by the \u00ab\u00a0fsck\u00a0\u00bb program to determine the order of which filesystems checks are done at reboot time. The \u00ab\u00a0\/\u00a0\u00bb root filesystem should have a value of \u00ab\u00a01\u00a0\u00bb and other filesystems should have a value of \u00ab\u00a02\u00a0\u00bb. If this filed is not present or has a value of \u00ab\u00a00\u00a0\u00bb then it is assumed that no check is to take place.<\/p>\n
