Humble,
Gluster 3.4 server bits with 3.6 client bits should work fine.
But I think the reserve (i.e. 3.6 server bits with older client bits)
are not compatible because of below issues
* Older clients can not mount the newly created volume on 3.6 . This
is because readdir-ahead will be enabled on the volume by default
which isn't present in older clients.
* We can't run rebalance on any volume created with 3.6 bits ( with
or without readdir-ahead) when older clients are connected. The
rebalance command will error out if older clients are connected.
Thanks,
