Hello Strahil

> What options do you use i  your cluster?

I'm not sure what exact info you would like to see?

Here's how clients mount the GlusterFS volume:
$ fgrep gluster /proc/mounts
tp-glusterfs5:/glusterfs /net/glusterfs fuse.glusterfs
0 0

Here's some server-side info:

$ sudo gluster volume info glusterfs

Both server and clients are running v6.5 and op-version is 60000 everywhere.
