2.3.1 Soft RAID Conguration with YaST
The YaST RAID conguration can be reached from the YaST Expert Partitioner, de-
scribed in Section 2.1, “Using the YaST Partitioner” (page 39). This partitioning tool
enables you to edit and delete existing partitions and create new ones to be used with
soft RAID:
1
Select a hard disk from Hard Disks.
2
Change to the Partitions tab.
3
Click Add and enter the desired size of the raid partition on this disk.
4
Use Do not Format the Partition and change the File System ID to 0xFD Linux
RAID. Do not mount this partition.
5
Repeat this procedure until you have dened all the desired physical volumes
on the available disks.
For RAID 0 and RAID 1, at least two partitions are needed—for RAID 1, usually ex-
actly two and no more. If RAID 5 is used, at least three partitions are required. It is
recommended to utilize partitions of the same size only. The RAID partitions should
be located on different hard disks to decrease the risk of losing data if one is defective
(RAID 1 and 5) and to optimize the performance of RAID 0. After creating all the
partitions to use with RAID, click RAID > Add RAID to start the RAID conguration.
In the next dialog, choose between RAID levels 0, 1, 5, 6 and 10. Then, select all parti-
tions with either the “Linux RAID” or “Linux native” type that should be used by the
RAID system. No swap or DOS partitions are shown.
