Are you talking about storage pool or volume on the storage pool? You can
take snapshot of the volume only…

To see Shared storage pools, go to Infrastructure->Zones->select the
zone->Primary Storage -> Select primary storage. For each primary storage
we show 2 buttons: "Edit" and "Enable Maintenance mode"

As for the volume, ROOT volume of the vm can be deleted only as a part of
vm expunge, never on its own.
