Snapshots and regular ro/rw mounts are essentially-different within the meaning whether the checkpoint is static or not and is marked with a snapshot flag or not. The current implemenation, however, allows to remount a snapshot to a regular rw-mount if the checkpoint number equals the latest one. This transition is actually impossible since changing a checkpoint to a snapshot makes another checkpoint, thus the condition is never satisfied. This fixes the weird state of affairs, and specifically separates snapshots and regular rw/ro-mounts. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp> |
