When the snapshot reserve is set to a value greater than 0%, this reserved space
will be dedicated entirely to snapshots. The free space in a storage pool will be
lower after the value is set and the snapshots will only use the space reserved.
When the space used for snapshots exceeds the snapshot reserve, the system will
start recycling older snapshots regardless the snapshot limitation set in Snapshot
Global Settings .
To set snapshot reservation, follow these steps:
1. Go to "Storage Manager" > "STORAGE" > "Storage Space".
2. Double click a storage pool to set reserved space for snapshots and to bring up the
Storage Pool Management page.
3. Click "Actions" > "Set Snapshot Reserved", enter a value for snapshot reserved
space, and click "Apply".
