RedHat cluter manager

Steps

Attach the firewire disk

[root@indl224ad etc]# fdisk -l

Disk /dev/sda: 80.0 GB, 80026361856 bytes
64 heads, 32 sectors/track, 76319 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes

Device Boot Start End Blocks Id System
/dev/sda1 1 9538 9766896 83 Linux
/dev/sda2 9539 19076 9766912 83 Linux
/dev/sda3 19077 28614 9766912 83 Linux

/dev/sda7 28807 29761 977904 83 Linux
/dev/sda8 29762 44067 14649328 83 Linux


Here I mapped /dev/sda1 and /dev/sda2 as the quorum disks.

Enter the following in the file /etc/syconfig/rawdevices

/dev/raw/raw1 /dev/sda5
/dev/raw/raw2 /dev/sda6

And do

service rawdevices start

after this issue the command the

raw -qa

And install the redhat cluster software on both the nodes ,

Configure the redhat cluster , and run the command ,

service clumanger start

to stop the cluster ,

stop the cluster by giving the command ,

service clumanager stop
service rawdevices stop

and do the same on other machine.
