Not at the moment I really haven't had time to dig into it this week yet.
I'll quote Lindsay Mathieson 's response and maybe she can chime in if she
sees this chain.

--------------------------------------------------------------
Hi David, I did a quick test this morning with Proxmox and 3.7.13 and was
able to get it working with the fuse mount *and* libgfapi.

One caveat - you *have* to enable qemu caching, either write-back or
write-through. 3.7.12 & 13 seem to now disable aio support, and qemu
requires that when caching is turned off.

There are setting for aio in gluster that I haven't played with yet.
-----------------------------------------------------------------

Did you revert client and server's to 3.7.11?  It could be also that we had
2 completely different issues.  The only similarity being the recent
upgrades and Operation not permitted messages.
