So, I'm still not getting fence_mpath working. This is all on CentOS 7.
Here's what I did:
- on each node, put a unique "reservation_key" in /etc/multipath.conf
defaults{} section (node1=20170001 and node2=20170002)
- created the STONITH device on node1 with:
pcs stonith create multipath fence_mpath
devices=/dev/mapper/36000d310013096000000000000000043 key=20170001 meta
provides=unfencing
It creates, but any time anything tries to fence (manually or by
rebooting a node), I get errors in /var/log/messages. Trying to
manually fence a node gets:
# pcs stonith fence node2 --off
Error: unable to fence 'node2'
Command failed: No such device
Another issue I run into is that fence_mpath tries to access/write to
/var/run/cluster/mpath.devices, but nothing else creates that directory
(and it seems that fence_mpath tries to read from it before writing it
out).
Anybody using fence_mpath as a STONITH device with pacemaker/corosync on
CentOS 7?
