[ovirt-users] FC Storage recover

Hi, We have a 4 node cluster (4.4.10) and a standalone manager. We attached to this cluster 4 volumes on FC. Last week we lost the storage canisters (both), but recovered one of them from the storage disks. Unfortunatly only 3 storages came back from offline. I see the 4th FC ID, but it's on "Can't Extend" status. If i check the storages on nodes (lsblk), i can see only the ID not more on this 4th storage. Do you know any recovery tool or any idea for this situation? Thanks csabany
