Hi.
This is related to the previous email, "Advisory ordering on clones
not working",
http://oss.clusterlabs.org/pipermail/pacemaker/2012-February/013119.html.
I read some more about advisory ordering and it seems it's not what
I'm looking for. Advisory ordering gets activated _only and only if
both resources need to start at the same time_, so I guess the
behaviour I am experiencing is how it should work.
Given the configuration below, I would like for the
p_fs_nfs_config_nocmc1 resource to not get restarted after one of the
storage nodes failure. It seems that symmetrical=false doesn't help,
the resource still gets restarted. The reason for this is I need the
NFS client mount to not be touched so that the processes using that
mount don't fail.
