Historically when there was not support to revert external snapshots this produced error message. error: Failed to revert snapshot s1 error: internal error: Invalid target domain state 'disk-snapshot'. Ref= using snapshot reversion Now we can simply consider this as reverting to offline snapshot as the possible damage to file system is already done at the point of snapshot creation.
