File System ID
Even if you do not want to format the partition at this stage, assign it a file
system ID to ensure that the partition is registered correctly. Possible values
include Linux, Linux swap, Linux LVM, and Linux RAID.
File System
Change the file system or format the partition here. Changing the file system
or reformatting partitions irreversibly deletes all data from the partition.
Ext3 is the default file system for the Linux partitions. ReiserFS, JFS, XFS,
and Ext3 are journaling file systems. These file systems are able to restore
the system very quickly after a system crash, because write processes are
logged during the operation. Furthermore, ReiserFS is very fast in handling
lots of small files. Ext2 is not a journaling file system. However, it is rock
solid and good for smaller partitions, because it does not require much disk
space for management.
Encrypt File System
If you activate the encryption, all data is written to the hard disk in encrypted
form. This increases the security of sensitive data, but slightly reduces the
system speed, because the encryption takes some time. More information
about the encryption of file systems is provided in Chapter 11, Encrypting
Partitions and Files (↑Security Guide).
Fstab Options
Specify various parameters contained in the global file system administration
file (
/etc/fstab
). The default settings should suffice for most setups.
You can, for example, change the file system identification from the device
name to a volume label. In the volume label, use all characters except
/
and
space.
To get persistent devices names, use the mount option Device ID, UUID or
LABEL. In SUSE Linux Enterprise Server, persistent device names are en-
abled by default.
NOTE: IBM System z: Mounting by path
Since mounting by ID causes problems on IBM System z when using
disk-to-disk copying for cloning purposes, devices are mounted by
path in
/etc/fstab
on IBM System z by default.
