Came in this morning to update to 3.7.12 and noticed that 3.7.13 had been released. So shut down VM's and gluster volumes and updated.<br>
update process itself went smoothly but on starting up oVirt engine the main gluster storage volume didn't activate. I manually activated and it came up but oVirt wouldn't report on how much space was used. However ovirt nodes did mount and allow me to start VM's. However after a few minutes it would claim to be inactive again even if the nodes themselevs still had access and mounted volumes and the VM's were still running. Found these errors flooding the gluster logs on nodes.<br>

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.<br>
<br>
<br>
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.<br>
<br>
<br>
There are setting for aio in gluster that I haven't played with yet.<span class=""><font color="#888888"><br>
