you have to go through the multipath device node. This makes perfect sense exact that pacemaker wants to mount the filesystem before multipath has created the device node.
I notice there is a Delay agent, but that seems like a bit of a hack
unusable, -
how much of a delay is enough, without waiting unnecessarily long?
Any suggestions?
This sounds like something I should know the answer to, but don't.
I'd never recommend the Delay agent, because it's just a fixed delay, which is... ugly. It may perhaps be better to (somehow) not start Pacemaker at all until after multipath had settled down.
Pacemaker does the iscsi for me in this case, so that's not an option in my current configuration. It could be an option though as the volumes I'm working with right now are ocfs2 and cloned to all nodes. Once I start setting up VM's I'll want the iSCSI volumes added and removed on demand though so it is still a problem that needs solving.
You might try #linux-ha or #linux-cluster on freenode in a few hours time (after the Europeans wake up). Otherwise you'll just be chatting with me :)
I never got the hang of IRC. It always seemed too busy. James
