[Gluster-users] Problems with Glusterfs and OpenVz

Hello again.

I just managed to install Proxmox on a new 64 bit machine. I then
removed the 32bit brick and peer from the gluster cluster and added
this new machine and rebalanced the volume.
Then I mounted the volume and started an OpenVZ container and I got
the same results (transport endpoint not connectd).
Tomorrow I will try recreating the volume from scratch on both the 64
bit machines.
Any other tests I might try?

Thanks,
Alessandro
