openstack volume snapshot show <snapshot_name>

It is recommended to detach the volume from the server before making a snapshot, to avoid potential crashes. This can be done with the command

openstack server remove volume <server> <volume>

and it can be reattached after the snapshot with

openstack server add volume <server> <volume>

Note that in order to make a snapshot without detaching the volume the --force  flag must be provided. The snapshot or backup of an attached volume is crash consistent.
