Re: To check RBD cache enabled

[Jean-Charles Lopez <jelopez@xxxxxxxxxx>]

Hi 

syntax uses the admin socket file : ceph --admin-daemon /var/run/ceph/$cluster-$type.$id.$pid.$cctid.asok config get rbd_cache

Should be /var/run/ceph/ceph.client.admin.$pid.$cctid.asok if your connection is using client.admin to connect to the cluster and your cluster name is set to the default of ceph. But obviously can’t know from here the PID and the CCTID you will have to identify.

You can actually do a ls /var/run/ceph to find the correct admin socket file

Hi,

I am following this article :

http://ceph.com/geen-categorie/ceph-validate-that-the-rbd-cache-is-active/

I have enabled this flag in ceph.conf

[client]
admin socket = /var/run/ceph/$cluster-$type.$id.$pid.$cctid.asok
log file = /var/log/ceph/

But the command to show the conf is not working :

[cephuser@ceph-las-admin-a1 ceph-cluster]$ sudo ceph --admin-daemon  /etc/ceph/ceph.client.admin.keyring config show
admin_socket: exception getting command descriptions: [Errno 111] Connection refused
