Hi All,
After search some articles and mailing list and try my best, my ceph
datastore can't monitor the capacity.
1) How can opennebula detect the size of ceph?
- Opennebula is a ceph-mon?
If yes, how can oneadmin user can run the rados command to show
the capacity, only root can do that? It must be "sudo rados", right?
- The opennebula accesses to ceph-mon(font-end) with password-less
to run "ssh ho-srv-ceph-02 rados df | grep Total"
If yes, i need an user oneadmin in ceph-mon and ability to run
rados df without sudo, so how? only root can run rados in this case.
2) Was any step i missed ?
Some description for my system:
Ceph:
- Deploy: ho-srv-ceph-01
- MON,OSD: ho-srv-ceph-02,ho-srv-ceph-03,ho-srv-ceph-04
- Sudo: "ceph ALL = (root) NOPASSWD:ALL" for all
Opennebula:
For testing ceph datastore only, i use one standalone server with
oneadmin user
Opennebula: cloudlab-02
Prepare for ceph:
- password-less from ceph-deploy
- Sudo: "ceph ALL = (root) NOPASSWD:ALL" for all
- in ceph-deploy
[root@ho-srv-ceph-01 ~]#ceph-deploy install cloudlab-02
I use use ceph to access from ceph to opennebula and user oneadmin to
access from opennebula to ceph
Following the official document:
- in ceph monitor
[root@ho-srv-ceph-02 ~]# ceph osd pool create one 64
- in opennebula front-end
[oneadmin@cloudlab-02 ~]$ cat ceph.one
NAME = ceph
DS_MAD = ceph
TM_MAD = ceph
DISK_TYPE = RBD
POOL_NAME = one
BRIDGE_LIST = ho-srv-ceph-02
[oneadmin@cloudlab-02 ~]$ vi ceph.one
[oneadmin@cloudlab-02 ~]$ onedatastore create ceph
ceph1.one ceph2.one ceph.one
[oneadmin@cloudlab-02 ~]$ onedatastore create ceph.one

Thank you.
