Hi,
Niels, its turned out that I had one of the options you told me to set already on (performance.read-ahead: off). After I added the second one (performance.write-behind: off) it seem like this problem does not exists any more. At least I installed twice D8 with with Mate. I will do more tests to be certain about that. As for now, can we speak, that recommended options for qemu VM storage are:
server.allow-insecure: on
cluster.server-quorum-type: server
cluster.quorum-type: auto
network.remote-dio: enable
cluster.eager-lock: enable
performance.stat-prefetch: off
performance.io-cache: off
performance.read-ahead: off
performance.quick-read: off
performance.write-behind: off
How bad this affects volume performance (if it does, of course) ?

here is one of the errors example. its like files that debian installer copies to the virtual disk that is located on glusterfs storage are getting corrupted.in-target is /dev/vda1--2015-07-14 11:49 GMT+03:00 Roman <romeo.r@xxxxxxxxx>:Ubuntu 14.04 LTS base install and then mate install was fine!Forgot to add, that debian8 installs OK on local disks.--2015-07-14 9:30 GMT+03:00 Roman <romeo.r@xxxxxxxxx>:Hi,I've reported a lot on gluster-users list, but seems, like noone is excited because of this bug. I think devs should try this out in their lab.In short:Running latest proxmox VE with these versions:Linux services 2.6.32-37-pveQEMU emulator version 2.2.1Running 2 gluster servers with Replica and Distributed volumes, both server and client side of gluster are updated to glusterfs 3.6.4 yesterday. Before that was 3.5.4 with same behavior.Problem:I'm not able to install Debian 8 on gluster volumes. It just randomly aborts installation on random step:If we talk about base system, it aborts on mirror selecting step (just keeps saying, there is networking problems and unable to connect to any mirror (while i do can ping them all from console). Or it aborts (if got downloaded packages) on installation steps complaining about not solved depndecies due to unsuccessfull install one of them (the most often is python-gtk2 pkg, when I install with Mate)Once I was lucky enough to insall the base system, but after reboot it was not usable, i wasn't able to run even apache, it always said there are no modules, while they were on their place. So i think they were corrupted.And such behavior is only with debian8, debian7 installs and runs perfectly, same as centos6 on all of my 4 proxmox nodes.I did md5sum of the installation iso, it is ok.I'll try today Latest Centos and Ubuntu just to check.But please, test the same in your lab or tell me what should i check for to help you to trace the bug.. There are no bad logs in gluster log files also.--Best regards,
