Hey Devid, I have the very same problem on my test-cluster, despite on running ovirt 4.0. If you access your volumes via NFS all is fine, problem is FUSE. I stayed on 3.7.13, but have no solution yet, now I use NFS.

I'm creating a test box I can more thoroughly mess with so I can submit to bugzilla something. Since my errors all popped up while trying to get ovirt and gluster functional again rather than thoroughly gather logs and test my data is kinda sketchy. *David Gossage* *Carousel Checks Inc. | System Administrator* *Office* 708.613.2284 On Thu, Jul 21, 2016 at 8:18 AM, Scott <romracer(a)gmail.com&gt; wrote:

Hi David, My backend storage is ZFS. I thought about moving from FUSE to NFS mounts for my Gluster volumes to help test. But since I use hosted engine this would be a real pain. Its difficult to modify the storage domain type/path in the hosted-engine.conf. And I don't want to go through the process of re-deploying hosted engine.

You change the cache mode using a custom property per-VM I believe. I don't know if this would work for the hosted engine.

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. -Krutika On Fri, Jul 22, 2016 at 7:17 PM, David Gossage <dgossage(a)carouselchecks.com&gt; wrote:

Hi, Unfortunately I can’t test this right away nor give exact steps how to test this. This is just a theory but please correct me if you see some mistakes. oVirt uses cache=none settings for VM’s by default which requires direct I/O. oVirt also uses dd with iflag=direct to check that storage has direct I/O enabled. Problems exist with GlusterFS with sharding enabled and bricks running on ZFS on Linux. Everything seems to be fine with GlusterFS 3.7.11 and problems exist at least with version .12 and .13. There has been some posts saying that GlusterFS 3.8.x is also affected. Steps to reproduce: 1. Sharded file is created with GlusterFS 3.7.11. Everything works ok. 2. GlusterFS is upgraded to 3.7.12+ 3. Sharded file cannot be read or written with direct I/O enabled. (Ie. oVirt uses to check storage connection with command "dd if=/rhev/data-center/00000001-0001-0001-0001-0000000002b6/mastersd/dom_md/inbox iflag=direct,fullblock count=1 bs=1024000”) Please let me know if you need more information. -samuli

Had a chance to upgrade my cluster to Gluster 3.7.14 and can confirm it works for me too where 3.7.12/13 did not. I did find that you should NOT turn off network.remote-dio or turn on performance.strict-o-direct as suggested earlier in the thread. They will prevent dd (using direct flag) and other things from working properly. I'd leave those at network.remote-dio=enabled and performance.strict-o-direct=off.
