Chapter 3: Creating the Cluster

Creating the Cluster in SuSE Linux Enterprise Server (SLES)

Perform the following step to set up the stonith_sbd fencing mechanism.

1.

Create the sbd header and set the watchdog timeout to 52 seconds and mgswait timeout to 104 seconds by
entering the following at the command prompt:

sles-ha1:~ # sbd -d /dev/disk/by-id/wwn-0x600605b00316386019265c4910e9a343-

part1 -4 104 -1 52 create

The following output appears.

Initializing device /dev/disk/by-id/wwn-0x600605b00316386019265c4910e9a343-

part1

Creating version 2 header on device 3

Initializing 255 slots on device 3

Device /dev/disk/by-id/wwn-0x600605b00316386019265c4910e9a343-part1 is

initialized.

2.

Verify that the sbd header was created and timeout set properly by entering the following at the command
prompt:

sles-ha1:~ # sbd -d /dev/disk/by-id/wwn-0x600605b00316386019265c4910e9a343-part1 dump

The following output appears.

==Dumping header on disk /dev/disk/by-id/wwn-

0x600605b00316386019265c4910e9a343-part1

Header version : 2

Number of slots : 255

Sector size : 512

Timeout (watchdog) : 10

Timeout (allocate) : 2

Timeout (loop) : 1

Timeout (msgwait) : 104

==Header on disk /dev/disk/by-id/wwn-0x600605b00316386019265c4910e9a343-part1

is dumped

3.

Add the contents to /etc/sysconfig/sbd by entering the following at the command prompt:

sles-ha1:~ # cat /etc/sysconfig/sbd

The following output appears.

SBD_DEVICE="/dev/disk/by-id/wwn-0x600605b00316386019265c4910e9a343-part1"

SBD_OPTS="-W"

4.

Allocate a slot for the node 1 for sbd by entering the following at the command prompt:

sles-ha1: # scp /etc/sysconfig/sbd root@sles-ha2:/etc/sysconfig/

sles-ha1:/etc/sysconfig # sbd -d /dev/disk/by-id/wwn-

0x600605b00316386019265c4910e9a343-part1 allocate sles-ha1

The following output appears.

Trying to allocate slot for sles-ha1 on device /dev/disk/by-id/wwn-

0x600605b00316386019265c4910e9a343-part1.

slot 0 is unused - trying to own

0x600605b00316386019265c4910e9a343-part1.

5.

Allocate a slot for the node 2 for sbd by entering the following at the command prompt:

sles-ha1:/etc/sysconfig # sbd -d /dev/disk/by-id/wwn-

0x600605b00316386019265c4910e9a343-part1 allocate sles-ha2
