I've been handed an odd situation. We have Dell R420 servers with four drives. For what we're up to, we want to have separate installs of CentOS on all four drives. However, the servers were ordered with an integrated PERC H710 RAID controller, which doesn't allow for direct pass-through of the drives (confirmed in a call with Dell). The closest we can get to having the single drives is a single disk RAID 0 array.
When it comes to copying our template CentOS install, the RAID configuration seems to knock out the possibility of using tools like dd or clonezilla, given that they're seen afterward by the RAID controller as foreign and have to be initialized. Due to administrative hurdles, returning the servers for ones without the RAID isn't on the table.
Our current method is to install CentOS on each drive and then do an rsync, but the logical volume structure isn't re-created in this, and we have to tweak it. Anyone have any ideas on a less painful way to copy these installs? The hardware is the same all around.
Thanks for any help.
