RHEV: Hosts in a cluster become Non-Operational after an addition of a new Storage Domain
Environment
Red Hat Enterprise Virtualization (RHEV) v2.2
Issue
All hosts but SPM, will become non-oprational after an addition of a new Storage Domain to a cluster that has been configured in a Fiber Channel Data Center.
Resolution
Restart the vdsmd service an all the non-operational hosts. This will cause vdsm to refresh the LVM filter.
Root Cause
This issue occurs because LVM filter has not been updated, it causes the VG list not to be updated with the newly added VG.
Diagnostic Steps
View the vdsm.log on the non-operational host.
The refresh thread strats with:
"Run and protect: refreshStoragePool..."
and results in:
