[ovirt-users] data(Master) storage domain is inactive / Failed to Reconstruct Master Domain

Hi all, After a power outage, I face a big issue with my setup: -Under "Compute ===> Data Centers" by Default DC status is "Non responsive" -Under "Compute ===>Data Centers ===> Default" all my storage domain are inactive even the Data (Master). Both of by storage domaine ISO and Data(master) are NFS based. The NFS node is up and running and oVirt file on the mount are accessible. log: -Failed to activate Storage Domain nas01-data2 (Data Center Default) by admin@internal-authz -Failed to Reconstruct Master Domain for Data Center Default. The result is that I can't start any of my VM. For you information, I have 23 VM running in this setup so wiping everything is not an option. Any idea how I can restore the storage domain? Thanks in advance -Joleking
