Need some advice and suggestions.
Have a bunch of brand new servers. The RAID controller is not supported by default Linux (OL6, OL7, RHEL, etc). So configuring the 2 internal disks as a RAID1 disk (mirrored logical drive) results in Linux not seeing the logical drive at all - and having to install on one of the two physical drives.
I see two choices.
Download the proprietary RAID controller driver for Linux from vendor and using it during the boot/install for Linux to use the RAID1 logical drive. I'm not keen on this as I dislike tainting the kernel.
Use the 2 physical disks, and do mirroring of the root/boot/UEFI/etc partitions using LVM? However, never really used LVM beyond the mere basics - as in installer creates volumes for you at install time.
Door number 1, or door number 2? Is there a door number 3?
