<br>
</span>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.<br>
<br>
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.<br>
<br>
Steps to reproduce:<br>
1. Sharded file is created with GlusterFS 3.7.11. Everything works ok.<br>
2. GlusterFS is upgraded to 3.7.12+<br>
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”)<br>
<br>
Please let me know if you need more information.<br>

> Well after upgrade of gluster all I did was start ovirt hosts up which launched and started their ha-agent and broker processes. I don't believe I started getting any errors till it mounted GLUSTER1. I had enabled sharding but had no sharded disk images yet. Not sure if the check for shards would have caused that. Unfortunately I can't just update this cluster and try and see what caused it as it has sme VM's users expect to be available in few hours.<br>
><br>
> I can see if I can get my test setup to recreate it. I think I'll need to de-activate data center so I can detach the storage thats on xfs and attach the one thats over zfs with sharding enabled. My test is 3 bricks on same local machine, with 3 different volumes but I think im running into sanlock issue or something as it won't mount more than one volume that was created locally.<br>

Last upgrade to 3.7.13 I had to rollback to 3.7.11 due to stability isues where gluster storage would go into down state and always show N/A as space available/used.
