CentOS 7 And Software Raid Minimal Install
I am trying to install CentOS 7 on a couple 4TB drives with software raid. In the Supermicro bios I set UEFI/BIOS boot mode to legacy. I
am using the CentOS 7 minimal install ISO flashed to a USB thumb drive.
So I do custom drive layout something like this using sda and sdb.
Create /boot as 512 MB XFS raid1 array.
Create SWAP as 32 GB SWAP raid1 array.
Create / on 3.xxx TB XFS raid1 array.
I then get error.
“Your BIOS-based system needs a special partition to boot from a GPT
disk label. To countinue, please create a 1MiB ‘biosboot’ type partition.”
I cannot seem to create the biosboot partition so it is mirrored to both drives for redundancy. Any ideas how to do this? I want everything mirrored to both drives.

Yeah, you need to create the 1M partition, preferably the first, and its type, like ext4 or xfs or swap, is, in the dropdown, biosboot.

Is there a way to get this partition mirrored on both drives?

Using software RAID? Build one drive, then add in the other. You do give RAID the whole drive….

This is the relevant part of a kickstart of a raid1 setup I have used 2 weeks ago for a 3 members RAID1 on 6 TB hard disks (legacy boot, no UEFI).
clearpart –all –drives=sda,sdb,sdc –initlabel
#initial setup only
