where:
first field
Describes the block special device or remote filesystem to be mounted.
second field
Describes the mount point for the filesystem. If the name of the mount point contains spaces these can be escaped.
third field
Describes the type of the filesystem. For the filesystems currently supported by the running kernel, see /proc/filesystems/.
fourth field
Describes the mount options associated with the filesystem.
fifth field
Is used for these filesystems by the dump 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.
sixth field
Is used by the fsck program to determine the order in which filesystem checks are done at reboot time. The root filesystem should be specified with a fs_passno of 1, and other filesystems should have a fs_passno 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.
Mounting Network File Systems
Even if a network file system is specified in /etc/fstab, the filesystem is not mounted unless netfs service is started. For more details see netfs.
Mount a File System at Boot
Specify it in /etc/fstab:
... /dev/sdc1 /generic-storage ext4 defaults 0 0 ...
