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) ?

>>> 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-pve
>>> QEMU emulator version 2.2.1
>>> Running 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.
