[ClusterLabs] dead cluster after centos update

[Dimitri Maziuk]

I've a 2-node ZFS cluster that was working fine until redhat improved my
user experience. Now, it's dead.

How do I get it back?

There was two resources: ZFS and IP. ther was fence_scsi that is now
logging

I disabled it for now, and

pcs resource debug-start resource-zfs --full

works fine: the pool is imported, filesystems are mounted and exported
-- but the resources remain stopped no matter what.

I don't see anything useful in the logs. How do I unfsck this mess?
