Description

Nithya noticed that group IDs end up being very similar:

$ rbd group create grp1
$ rbd group create grp2
$ rbd group create grp3
$ rbd group create grp4

$ rados -p rbd ls | grep rbd_group_header
rbd_group_header.10256b8b4567
rbd_group_header.10216b8b4567
rbd_group_header.10236b8b4567
rbd_group_header.101f6b8b4567
