Each filesystem +is described on a separate line; fields on each line are separated by tabs +or spaces. The order of records in +<B>fstab</B> +is important because fsck (8), mount (8), and umount (8) sequentially iterate through +<B>fstab</B> +doing their thing. +<P> +The first field, +<B>fs_spec</B> +describes the block special device or remote filesystem to be mounted. +<P> +The second field, +<B>fs_file</B> +describes the mount point for the filesystem. For swap partitions, this +field should be specified as ``none''. +<P> +The third field, +<B>fs_vfstype</B> +describes the type of the filesystem. The system currently supports three +types of filesystems: +<UL> +<LI> +<B>minix</B> +<BR> +a local filesystem, supporting filenames of length 14 or 30 characters. +<LI> +<B>ext</B> +<BR> +a local filesystem with longer filenames and larger inodes. This +filesystem has been replaced by the +<B>ext2</B> +file system, and should no longer be used. +<LI> +<B>ext2</B> +<BR> +a local filesystem with longer filenames, larger inodes, and lots of other +features. +<LI> +<B>xiafs</B> +<BR> +a local filesystem with longer filenames, larger inodes, and lots of other +features. +<LI> +<B>msdos</B> +<BR> +a local filesystem for MS-DOS partitions. +<LI> +<B>hpfs</B> +<BR> +a local filesystem for HPFS partitions. +<LI> +<B>iso9660</B> +<BR> +a local filesystem used for CD-ROM drives. +<LI> +<B>nfs</B> +<BR> +a filesystem for mounting partitions from remote systems. +<LI> +<B>swap</B> +<BR> +a disk partition to be used for swapping. +</UL> +<P> +If +<B>vfs_fstype</B> +is specified as ``ignore'' the entry is ignored. This is useful to show +disk partitions which are currently unused. +<P> +The fourth field, +<B>fs_mntops</B> +describes the mount options associated with the filesystem. +It is formatted as a comma separated list of options. It contains at least +the type of mount plus any additional options appropriate to the filesystem +type. For documentation on all of the available options, see mount (8). +<P> +The fifth field, +<B>fs_freq</B> +is used for these filesystems by the dump (8) command to determine which +filesystems need to be dumped. If the fifth field is not present, a value +of zero is returned and dump will assume that the filesystem does not need +to be dumped. +<P> +The sixth field, +<B>fs_passno</B> +is used by the fsck (8) program to determine the order in which filesystem +checks are done at reboot time. The root filesystem should be specified +with a +<B>fs_passno</B> +of 1, and other filesystems should have a +<B>fs_passno</B> +of 2. Filesystems within a drive will be checked sequentially, but +filesystems on different drives will be checked at the same time to utilize +parallelism available in the hardware. If the sixth field is not present +or zero, a value of zero is returned and fsck will assume that the filesystem +does not need to be checked. +<P> +The proper way to read records from +<B>fstab</B> +is to use the routines getmntent (3). +<H1>FILES</H1> +<B>/etc/fstab</B> +resides in +<B>/etc</B> +<H1>SEE ALSO</H1> +getmntent (3), mount (8), swapon (8) +</BODY> +</HTML> |
