Delete Partition Table and Disk Label
This completely overwrites the old partition table. For example, this can be helpful
if you have problems with unconventional disk labels. Using this method, all data
on the hard disk is lost.
More Partitioning Tips
If the partitioning is performed by YaST and other partitions are detected in the system,
these partitions are also entered in the file /etc/fstab to enable easy access to this
data. This file contains all partitions in the system with their properties, such as the file
system, mount point, and user permissions.
Example 8.1 /etc/fstab: Partition Data
/dev/sda1
/dev/sda5
/dev/sda6
The partitions, regardless of whether they are Linux or FAT partitions, are specified
with the options noauto and user. This allows any user to mount or unmount these
partitions as needed. For security reasons, YaST does not automatically enter the exec
option here, which is needed for executing programs from the location. However, to
run programs from there, you can enter this option manually. This measure is necessary
if you encounter system messages such as "bad interpreter" or "Permission denied".
Partitioning and LVM
From the expert partitioner, access the LVM configuration with LVM (see
"LVM Configuration"
exists on your system, it is automatically activated as soon as you enter the LVM con-
figuration for the first time in a session. In this case, any disks containing a partition
belonging to an activated volume group cannot be repartitioned because the Linux
kernel cannot reread the modified partition table of a hard disk when any partition on
this disk is in use. However, if you already have a functioning LVM configuration on
your system, physical repartitioning should not be necessary. Instead, change the con-
figuration of the logical volumes.
At the beginning of the physical volumes (PVs), information about the volume is written
to the partition. To reuse such a partition for other non-LVM purposes, it is advisable
