<br>
We've been using the same settings, found in an old email here, since<br>
v3.7 of gluster for our VM hosting volumes. They've been working fine<br>
but since we've just installed a v6 for testing I figured there might<br>
be new settings I should be aware of.<br>
<br>
So for access through the libgfapi (qemu), for VM hard drives, is that<br>
still optimal and recommended ?<br>
