fstab configuration

The fstab file (/etc/fstab) governs which mount points the system is aware of.

Fields in the File System Table (fstab) §

The basic structure of the file is as follows:

$device $mount_point $fs_type $mount_options $dump_options $check_options

For example, the floppy disk (if you still have one) is:

/dev/fd0    /mnt/floppy    auto    rw,noauto,user,sync    0    0

Baseline fstab §

By default there are few entries, the init scripts will mount many of the absolutely necessary things.

/dev/sda1		/		ext3		noatime		0 1
/dev/sda2		none		swap		sw		0 0
shm			/dev/shm	tmpfs		nodev,nosuid,noexec	0 0

CIFS (Samba) Entries in fstab §

The most important thing here is the options and credentials, this example shows a simple share on server WinR2D2. Adjust the path to the credentials file as necessary and properly set permissions (0600).

//winr2d2/public /mnt/public cifs dir_mode=0777,file_mode=0666,uid=500,gid=500,credentials=/opt/edoceo/etc/auth.cifs 0 0

Here is a sample credentials file


GlusterFS Entries in fstab §

Super handy to auto-mount to a Gluster system on boot - for /home maybe or some large shared repository

SSHFS (FUSE) in fstab §

Replace the $ prefixed items with proper values for your environment

sshfs#$user@$host:/$path    /mnt/$host    fuse    comment=sshfs,noauto,users,transform_symlinks    0    0
