Why VM-level snapshots on FC storage, when nowadays these storage b= oxes are smart enough to do LUN-level snapshots. All it would require is pro= per layout on the storage side. If a LUN (or more LUNs) is dedicated to a VM= , then you need to freeze the writes in a VM for a little and call the API o= f the storage to snapshot the LUN. Removal of a snapshot would be fully tran= sparent. Where it gets more complicated is an app-aware snapshot. And revert= to a snapshot, that would have to be done very carefully, nodes should not s= tart panicking that they lost storage. Is this what you meant? Regards, Karel > On 2026.
