In this installationexample, each device has a unique size so it is easier to map. Now link the block devices to the rawdevices on all nodes by modifying /etc/sysconfig/rawdevices. Run ll on the device to get themajor minor number for a block device, as seen below.# ll /dev/sdc1brw-rw---- 1 root disk 8, 33 Oct 1 12:46 /dev/sdc1 #ocr1# ll /dev/sdd1brw-rw---- 1 root disk 8, 49 Oct 1 12:47 /dev/sdd1 #ocr2# ll /dev/sde1brw-rw---- 1 root disk 8, 65 Oct 1 12:47 /dev/sde1 #vote1# ll /dev/sdg1brw-rw---- 1 root disk 8, 97 Oct 1 12:48 /dev/sdg1 #vote2# ll /dev/sdh1brw-rw---- 1 root disk 8, 113 Oct 1 12:49 /dev/sdh1 #vote3Change the configuration file /etc/sysconfig/rawdevices using vi or your favorite editor and addthe following block devices.$ vi /etc/sysconfig/rawdevices
