Figure 15.4 Logical Volume Management
Click Add and go through the wizard-like popup that opens:
1. Enter the name of the LV. For a partition that should be mounted to /home
, a
selfexplaining name like
HOME
could be used.
2. Select the size and the number of stripes of the LV. If you have only one PV, se-
lecting more than one stripes is not useful.
3. Choose the filesystem to use on the LV as well as the mount point.
By using stripes it is possible to distribute the data stream in the LV among several PVs
(striping). If these PVs reside on different hard disks, this generally results in a better
reading and writing performance (like RAID 0). However, a striping LV with
n
stripes
can only be created correctly if the hard disk space required by the LV can be distributed
evenly to
n
PVs. If, for example, only two PVs are available, a LV with three stripes
is impossible.
