Hi all,
I’ve configured DRBD on two nodes running on CentOS6.3, it’s pretty good. The disks on two nodes can be synchronized succsssfully.
master1# cat /proc/drbd
0: cs:Connected ro:Primary/Secondary ds:UpToDate/UpToDate C r-----
ns:204840 nr:2087836 dw:2292676 dr:1037 al:50 bm:128 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0
master2# cat /proc/drbd
0: cs:Connected ro:Secondary/Primary ds:UpToDate/UpToDate C r-----
ns:2087836 nr:204840 dw:204840 dr:2087836 al:0 bm:128 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0
However, I came across problem when I integrate RHCS (Redhat Cluster Suite) to DRBD.
I’ve added the DRBD-proivided script /usr/local/drbd/share/cluster/drbd.sh as the RHCS resource.
<rm>
<resources>
<ip address="192.168.129.190" sleeptime="10"/>
<drbd name="mdisk" resource="ha"/>
<script file="/usr/local/drbd/share/cluster/drbd.sh" name="drbd_script"/>
</resources>
<service domain="drbd_domain" name="mdisk_svc" recovery="relocate">
<ip ref="192.168.129.190"/>
<script ref="drbd_script"/>
</service>
</rm>
However, when I relocate the service to another node, the script does not take any effect.
Then I tried to run this script manually. I guess the reason is the script does not know which device to promote/demote.
[root at master2 ~]# /usr/local/drbd/share/cluster/drbd.sh start

No resource names specified
How to integrate this script (drbd.sh) to RHCS? Should I feed the resource name to RHCS?
Thanks very much.
Regards,
CY
