Creating Logical Volumes
If you have already configured LVM on your system, the existing logical volumes can be specified
now. Before continuing, assign appropriate mount points to these logical volumes too. Click
Next to
return to the YaST Expert Partitioner and finish your work there.
4.6 Direct LVM Management
If you already have configured LVM and only want to change something, there is an alternative
method available. In the YaST Control Center, select
System > Partitioner . You can manage your
LVM system by using the methods already described.
4.7 Resizing an LVM Partition
You can increase the size of a logical volume by using the YaST partitioner, or by using the
lvextend
command. YaST uses
parted(8)
to grow the partition.
To extend an LV there must be enough unallocated space available on the VG.
LVs can be extended or shrunk while they are being used, but this may not be true for a filesystem
on them. Extending or shrinking the LV does not automatically modify the size of file systems in the
volume. You must use a different command to grow the filesystem afterwards. For information
about resizing file systems, see
Chapter 5, “Resizing File Systems,” on page 35 .
Make sure you use the right sequence:
Š
If you extend an LV, you must extend the LV before you attempt to grow the filesystem.
Š
If you shrink an LV, you must shrink the filesystem before you attempt to shrink the LV.
