How are you managing your LXC containers?

Are you using lxc utilties for the same ? or is it via docker [1]? If its docker, there is an option (-v) which allows you to attach  a volume to the container.

You can create a Fuse device inside the container by running mknod /dev/fuse c 10 229

Also, have you started the containers with full privileges ?

I am trying to deploy glusterfs server (3.5.2-2) on LXCs running Ubuntu 14.0.4. However I cannot find a viable method to attach an additional logical volume block device to LXC except using dev loop. GlusterFS volume is created and started without any problem. But the client fails to mount to glusterfs volume.

ubuntu@gserv-5:~$ sudo gluster volume create gv2 replica 2 gserv-5:/data/brick1/gv2  gserv-6:/data/brick1/gv2
volume create: gv2: failed: Host gserv-6 is not in 'Peer in Cluster' state

ubuntu@gserv-6:~$ sudo mount -t glusterfs gserv-5:/gv3 /mnt/gv3
Mount failed. Please check the log file for more details.

ubuntu@gserv-6:~$ mount

I am new to GlusterFS. Could someone help me to troubleshoot this issue please?
Thanks a lot!
