Hi all,
I have setup a rhel5 based cluster with three nodes. Sometimes i need
to start only two of this three nodes, but cluster services that i
configured doesn't starts (fenced fail). Is it not possible to start up
only two nodes on a three node cluster?? Maybe I need to adjust votes
param to two instead of three??
Could you be more specific about what you run, where, what happens,
what messages you see, etc.

Yes,
First, I attached my cluster.conf. When /etc/init.d/cman starts,
returns an ok, but when I try to mount my gfs partition returns this error:
[root@haldir cluster]# service mountgfs start
Mounting GFS filesystems: /sbin/mount.gfs: lock_dlm_join: gfs_controld
join error: -22
/sbin/mount.gfs: error mounting lockproto lock_dlm
[FAILED]
[root@haldir cluster]#
And of course any service couldn't start .... And clustat output is:
[root@haldir cluster]# clustat
Member Status: Quorate
Member Name ID Status

thranduil.hpulabs.org 1 Online

P.D: mountgfs it is a simple script that mounts gfs partitions because
gfs script provided by redhat doesn't works with _netdev param under fstab.
