Thanks David,

My settings are all defaults, i have just created the pool and started it.
I have set the settings as your recommendation and it seems to be the same issue;

Dears,

I have created a replicated striped volume with two bricks and two servers but I can't use it because when I mount it in ESXi and try to migrate a VM to it, the data get corrupted.
Is any one have any idea why is this happening ?

Dell 2950 x2
Seagate 15k 600GB
CentOS 7.2
Gluster 3.7.8

Appreciate your help.

Most reports of this I have seen end up being settings related.  Post gluster volume info. Below is what I have seen as most common recommended settings.

I'd hazard a guess you may have some the read ahead cache or prefetch on.

quick-read=off

read-ahead=off

io-cache=off

stat-prefetch=off

eager-lock=enable

remote-dio=on
