Bug Description
In one of customer deployments we faced the situation when host OS kernel would initialize multiple backplanes with disks in random order at boot time. This causes OSD disks that Fuel deployed w/ ceph-deploy utility to be lost from OSD after node reboot, since they were mounted via /dev/sdXXX pointers and these numbers become different at every boot.
The solution is to mount OSD disks using UUID instead of sdXXX names. It's needs to be checked whether ceph-deploy utility can do it (so Fuel could just pass additional parameter) or a more sophisticated approach is needed to solve this problem.
