Thanks Oliver,
Here is more details on the configuration. Server is part of Gluster 3
Replica Arbiter 1 server. The two primary servers are both running DDR-4
Multi Bit ECC Memory
Each Server is a Del Power Edge 630 running with
6x32 GB Memory
Perc H730P with 2 GB on board cache.
Raid 10 Array 8 Drives
Read Ahead
Write Through - 512K Stripe
Arbiter server is nothing special, just a server i have laying around.
Thank You,

Hi Bryan,
i expect a hardware problem.
Have all your servers ECC ram ?
In the past I had a PC (without ECC RAM) and without ovirt,
which regularly produced a defective data block when transferring
an 8GB gzip file with rsync. The error position in file was randomly, but
the defective stored block on disc has always only the first 128 bytes
scrambled.
You see, something like this can happen without any messages or anything
like that.
I didn't investigate further whether the cause was the network card, the RAM
or
the drive path or the switch port. But it was clearly reproducible!
my 2 cent.

Hi,
Over the past few weeks i have had a number of Windows VM Disk start showing
up as corrupted. I Attempt to boot into recover mode and run the normal
recover tools (chkdsk, sfc /scannow, etc.) Unable to repair with status 50.
Looking through Ovirt, i do not see any thing in the logs. VM is Running
off a gluster replica 3 volume. The corruption does not seem to be isolated
to one specific gluster volume. I have also seen corruption with an NFS
Volume. Issue seemed to start after moving from a Centos 7 Install, to a
Ovirt Node image.
I have mainly seen corruption with Windows 10 Images, but a couple of
2003/2012 server OS's as well.
Where would be the best place to start looking at why the VM HD's are
getting corrupted?
Thank You,
