I have installed in the host glusterfs-server 3.4.2. and in a VM glusterfs-client 3.2.7. When I mount the volumes in the vm I cannot access to them. Is it necessary to have in both places, host and vms, the same version of gluster? Thanks in advance.
We recommend that you use the same version on both client and server. On newer versions you can sometimes use newer clients. For questions like this we suggest you ask on IRC (#gluster on freenode) or on the gluster mailing lists.
