Hi Tibor,
It all depends on if you can risk the chance of downtime.
Buying a couple larger HDD's is probably cheaper than spending a couple
of hours of your time on it when things break. You could have one node
down permanently, replace it completly and heal the volume
(http://gluster.org/community/documentation/index.php/Gluster_3.4:_Brick_R...)
During this time the cluster is at risk and performance will suffer
during healing. I think if you use the same data disk healing will be
quick though.
Kind regards,

Hi Tibor,
In this if your host OS disk will crash your brick data also
inaccessible..better to have the RAID1 for OS...

Hi,
I would like to make a four-node gluster based cluster, but I
don't have enought hdd. I just wondering, on the hosts (not on the
portal) I won't use raid for the main system (os).
I have disks only for bricks. I will give one disk for the os, and
one disk for gluster brick per server.
Is it a good idea?
What will happen if the main system's hdd will break?
Can I recreate gluster+vdsm host without data loss?
How did I do it?
Thanks for advance.
Tibor
