Logical Volume Management
Figure 4-4
To create a new logical volume (see Figure 4-5), click Add and fill out the pop-up that opens. For
partitioning, specify the size, file system, and mount point. Normally, a file system, such as Reiserfs
or Ext2, is created on a logical volume and is then designated a mount point. The files stored on this
logical volume can be found at this mount point on the installed system. Additionally it is possible to
distribute the data stream in the logical volume among several physical volumes (striping). If these
physical volumes reside on different hard disks, this generally results in a better reading and writing
performance (like RAID 0). However, a striping LV with stripes can only be created correctly if
n
the hard disk space required by the LV can be distributed evenly to physical volumes. If, for
n
example, only two physical volumes are available, a logical volume with three stripes is impossible.
WARNING: YaST has no chance at this point to verify the correctness of your entries concerning
striping. Any mistake made here is apparent only later when the LVM is implemented on disk.
