[Linux-cluster] RHEL Cluster node fencing and cluster membership



Title: RHEL Cluster node fencing and cluster membership

Hi

I have two dl585 with shared storage from MSA 1000 in a two node rhel 5.3 cluster. Priority in cluster.conf are like below.

<failoverdomainnode name="usrylxap237.merck.com" priority="1"/>
                                <failoverdomainnode name="usrylxap238.merck.com" priority="2"/>

Whenever lower priority node usrylxap238 Is rebooted it kills cman on usrylxap237 (Higher priority node) and fence it causing reboot of it. Message I see in /var/log/messages of higher priority node is

Jun 26 11:02:36 usrylxap237 openais[4750]: [CMAN ] cman killed by node 2 because we rejoined the cluster without a full restart

Jun 26 11:03:57 usrylxap237 openais[27373]: [CMAN ] cman killed by node 1 because we were killed by cman_tool or other application

After reboot when higher priority node usrylxap237 comes up it tranfers services from lower priority node to itself and everything works fine for some time. Then I see following message in /var/log/messages of higher priority node running services.

Now my cluster is messed up. Even though clustat and cman_tool show everything is fine. As I can not move services between the node (they are running fine on present node). It even does not give any error message when I try to move them using clusvcadm.

I have clvmd running with locking_type = 3 and gfs2 file system mounted (using dlm) which now is hanging on higher priority node but is fine on lower priority node (Which seems is not part of cluster now).

[root usrylxap237 ~]# service gfs2 status
Active GFS2 mountpoints:
/oracluster1

[root usrylxap238 ~]# service gfs2 status
Configured GFS2 mountpoints:
/oracluster1
Active GFS2 mountpoints:

Not sure why cluster is loosing membership and getting staled and GFS file system is not accessible.

Thanks
