Hi All,
I just built a 3 node cluster (4.5.2) with 3 Virtual Disks on identical Dell Servers.
First Virtual Disk /dev/sda - BOSS Card - 450GB
Second Virtual Disk /dev/sdb - SSD 14TB
Third Virtual Disk /dev/sdc - HDD 72TB
All OS disks were /dev/sda before reboot
Following reboot only first Node is still /dev/sda - other 2 nodes are now /dev/sdc
This obviously makes it impossible to create VG groups and create Gluster storage
volumes.
Can anyone shed any light on why this is happening and how to prevent it.
Kind regards
Simon

I should clarify that the OS remains on the BOSS card (originally /dev/sda) but following
a reboot the device name has changed to /dev/sdc
8:16 a.m.
This is just normal. The /dev/sdX names are never stable, as they are
assigned during boot time.
And it depends which device module is loaded first, so names might change.
If you need stable naming, then use /dev/disk/by-xxx/ symlinks.

Thanks Jean-Louis,
I've never had an issue with them changing in the past.
Do you have some documentation/links that would help me in the oVirt enviroments please?
