Re: Access RBD pools from clients

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Clients need access to the public network in order to access ceph resources.



Zitat von Amjad Kotobi <kotobi@xxxxxxx>:

Hi,

I’m trying to access CEPH cluster from client machines via RBD for operations like listing pools, creating image, etc.. I put all needed keys/configuration in ceph directory and when I try to list pool rbd hung/wait forever
Client machine in IP range of: 136.172.26.0/24
The command e.g. I’m trying is

rbd -c /etc/ceph/ceph.conf  -p vms ls -n client.cinder4


My CEPH cluster configuration file “ceph.conf” is

##########

[global]
fsid = e6d92380-4d77-4064-8797-2722fecfd1f4
mon initial members = ceph1,ceph2,ceph3
mon host = 10.60.1.21,10.60.1.22,10.60.1.23
public network = 10.60.1.0/24
auth cluster required = cephx
auth service required = cephx
auth client required = cephx
mon_allow_pool_delete = true
osd pool default size = 3
osd pool default min size = 2

[mgr.ceph1]
mgr tick period = 10
mon mgr beacon grace = 60

[client.cinder4]
keyring = /etc/ceph/ceph.client.cinder4.keyring

##########

There is no firewall in between and accessing/telnet port is very much possible. I’m suspecting because of different IP subnet, MON CEPH is not allowing client.

Any idea and help on this will be great.

Thanks
Amjad
