#LINUX SOFTRAID SETUP WHICH DRIVES ARE MIRRORS HOW TO#

dev/sdc4 - 4GiB RAID1 Mirror for Swap Space dev/sdc2 - 500MiB RAID1 Mirror for /boot dev/sdb4 - 4GiB RAID1 Mirror for Swap Space dev/sdb3 - 500MiB RAID1 Mirror for /boot This way the partitioning scheme for /dev/sdb and /dev/sdc are identical.īut instead the CentOS Install Manual Partitioning wants to do: dev/sdc4 - 4GiB RAID1 mirror for Swap Space dev/sdc2 - 500MiB RAID1 mirror for /boot

dev/sdb4 - 4GiB RAID1 mirror for Swap Space dev/sdb2 - 500MiB RAID1 mirror for /boot What I'd like to do, in a software RAID1 system:

And then it wants to take control of the partition order for the remaining partitions.īut I cannot for the life of me figure out how to make just an empty /dev/sdc1 partition, so that I can deal with that after the install. The CentOS installer wants to make /boot/efi on /dev/sdb1 (/dev/sda is my USB install drive). This can be some what remedied by keeping a copy of /boot/efi some where on the second (or 3rd, or 4th.) disk.īut the problem I'm running into, the CentOS Install Manual Partitioning won't allow granular control of partition order. What happens if that drive fails and has to be replaced? The system won't boot because there's no alternative ESP to boot off of.

The ESP can only be installed on one partition on system.

I'm curious as to how people set up their partitions in an EFI system with software RAID.
