Operating Systems Linux Red Hat Linux Cluster failover issue Post 302896095 by munna529 on Friday 4th of April 2014 10:59:42 AM
Old 04-04-2014
Thanks for the information. i worked on windows cluster as we are doing some array based migrations using mpxtool(block level) copy. Now we are working on linux hosts and usually it is an offline migration.
I see some hosts are possible clusters so i want to determine which hosts are cluster ? We have suse systems so i figured out on one server it shows this output does that mean is this a cluster ?

Code:
     #-> find / -name hacluster /var/lib/heartbeat/cores/hacluster

[root@itsusral00019:/]#
Code:
     #-> find / -name cluster
 /lib/modules/2.6.16.60-0.97.1-smp/kernel/fs/ocfs2/cluster
 /lib/modules/2.6.16.60-0.101.1-smp/kernel/fs/ocfs2/cluster
 /lib/modules/2.6.16.60-0.97.1-kdump/kernel/fs/ocfs2/cluster
 /lib/modules/2.6.16.60-0.101.1-kdump/kernel/fs/ocfs2/cluster
 /opt/VRTSpbx/bin/cluster
 /usr/src/linux-2.6.16.60-0.101.1/fs/ocfs2/cluster

[root@itsusral00019:/]#
Code:
     #-> clustat -bash: clustat: command not found

[root@itsusral00019:/]#
Code:
     

     #-> hastatus -sum -bash: hastatus: command not found

from the above output i see this host doesn't have veritas cluster but there is some hacluster when i tried to look for cluster.conf file i dont see and i am not aware for this hacluster.

If you know anything about this please let me know this would be very helpful.
