OK, could you try the following:
i. Set network.remote-dio to off
# gluster volume set <VOL> network.remote-dio off
ii. Set performance.strict-o-direct to on
# gluster volume set <VOL> performance.strict-o-direct on
iii. Stop the affected vm(s) and start again
and tell me if you notice any improvement?
Previous instll I had issue with is still on gluster 3.7.11
My test install of ovirt 3.6.7 and gluster 3.7.13 with 3 bricks on a locak disk right now isn't allowing me to add the gluster storage at all.
Keep getting some type of UI error
Yes that is definitely a UI error. To get a better stack trace can you install the debuginfo yum install ovirt-engine-webadmin-portal-debuginfo ovirt-engine-userportal-debuginfo And recreate the exception, that should give a better stack trace.

Hi,
Thanks for the logs. So I have identified one issue from the logs for
which the fix is this: http://review.gluster.org/#/c/14669/. Because of a bug in the code, ENOENT was getting converted to EPERM and being propagated up the stack causing the reads to bail out early with 'Operation not permitted' errors.
I still need to find out two things: i) why there was a readv() sent on a non-existent (ENOENT) file (this
is important since some of the other users have not faced or reported this issue on gluster-users with 3.7.13)
ii) need to see if there's a way to work around this issue.
Do you mind sharing the steps needed to be executed to run into this
issue? This is so that we can apply our patches, test and ensure they fix the problem.
Unfortunately I can’t test this right away nor give exact steps how to
