Mounting, partitioning and configuring filesystems

Applicable to
S.u.S.E. version: all
Kernel version: all

Under Linux, several filesystems and filesystem types (e.g. ext2, minix, msdos, vfat ,iso9660) can be assembled into a great filesystem in /.

This mechanism is necessary, because under Linux different logic drives as e.g. in DOS (C:, D:, etc.) do not exist. All physical drives - same whether hard disk, diskette, CD-ROM drive, MO, ZIP drive, etc. - seem to the Linux system as filesystems, which are integrated into the above mentioned filesystem /.

One calls this procedure mount. When one wants to remove again a filesystem from the / filesystem, one speaks about unmount.

Conditions for joining and mounting filesystems are:

At the listing, the filesystems' sequence is to be observed. That means, the sequence in the file /etc/fstab should return the later mount sequence .

This is in general correctly arranged by YaST, so that e.g. /usr/local is mounted right after /usr . The mount command itself cannot take this into consideration and mounts the filesystem as the sequence appears in /etc/fstab.

Interesting for the use of either mount or /etc/fstab are the options user and noauto.

user allows to any user to mount or unmount a filesystem (interesting at the CD-ROM).

noauto arranges not to mount automatically at a system start the identified partition (particularly mount -a). It must be explicitly mounted manually. This is useful with media that are not always available at a system start (again here for example the CD-ROM).

Please read as well the article about Division of the hard disk into partitions.
