I may have figured this out. The systems that "failed" are running the Oracle "unbreakable" kernel:
3.8.13-98.el6uek.x86_64
The working systems are running the default CentOS 6 2.6 kernel.
There you go, this kernel is unfakeable ;) - fabian
and the error from the vdsm.log only show up on the UEK kernel.

Hi, I'm new to oVirt and recently built a 10 node ovirt 3.5 DC with shared storage using gluster configured as distributed-replicated (replication = 2). Shortly after 7 of the 10 nodes dropped, one at a time over a few hours, into "Non Operational" state. Attempting to activate one of these nodes gives the error: "Failed to connect Host ovirt-node260 to Storage Pool LADC-TBX". Attempting to put the node into Maintenance eaves the node stuck in "Preparing For maintenance".
When I rebooted one of the nodes I see this in the nodes event list:
"Host ovirt-node269 reports about one of the Active Storage Domains as Problematic."
I see many of these errors in the vdsm log from the failed nodes:

Any help here is appreciated.
