Hi all,

I have issue with creating shared storage for Openstack. Main idea is to 
create 100% redundant shared storage from two servers (kind of network 
RAID from two servers).
I have two identical servers with many disks inside. What solution can 
any one provide for such schema? I need shared storage for running VMs 
(so live migration can work) and also for cinder-volumes.

One solution is to install Linux on both servers and use DRBD + OCFS2, 
any comments on this?
Also I heard about Quadstor software and it can create network RAID and 
present it via iSCSI.


P.S. Glance uses swift and is setuped on another servers
