<div dir="ltr">Technically, (IIRC) a client of any GlusterFS 3.x version should be able to communicate with any GlusterFS 3.x servers, and provide basic operation.

What's the situation with mixing versions between client and server? For<br>
example I've just noticed that we're using glusterfs 3.4.0.59rhs on some<br>
clients (came with CentOS7) to talk to servers running 3.6.2. Is that<br>
considered OK, or would it be better to upgrade the clients to the one<br>
from the gluster repo?<br>
<br>
Cheers,<br>
