[Pacemaker] how to mount drive on SAN with pacemaker resource agent?

[Mike Diehn]

To make sure the failed server is actually dead, you want to use STONITH.
 So read about that.  Here are examples from our testing cluster.  These are
broken, so don't use them as they are.  That's why they are set to "Stopped"
right now.  I probably have some timing stuff very wrong:


primitive ShootLebekmfs1 stonith:external/ipmi \
        meta target-role="Stopped" \
        params hostname="lebekmfs1" ipaddr="10.1.1.59" userid="stonith"
passwd="ShootMeInTheHead" interface="lan"
primitive ShootLebekmfs2 stonith:external/ipmi \
        meta target-role="Stopped" \
        params hostname="lebekmfs2" ipaddr="10.1.1.61" userid="stonith"
passwd="ShootMeInTheHead" interface="lan"


You can use the ocf:heartbeat:Filesystem resource to mount any file system
you can mount manually.  Here's one from a config in our test cluster.  This
works:

primitive lvTest ocf:heartbeat:Filesystem \
        params device="/dev/EkmCluVG/lvTest" directory="/srv/test1"
fstype="ocfs2" \
        op monitor interval="10s" timeout="10s"


Make sure you remove the file system from your /etc/fstab if you're going to
do it this way.  During testing, for my convenience, I leave it in, but add
the noauto option to prevent it being mounted on boot.

Best,
Mike
