This is true, however it's a temporary measure only, and I have backups.
Once the prices drop again, I'll buy another 1.5TB disk and convert back
to a RAID5.

have you set the type to linux raid autodetect?
have you tried mdadm --assemble?

One of the disks had a GPT partition table which I was eventually able
to get rid of with gdisk (emerge -av gptfdisk).
I'm close. I had a 2.7TiB RAID5

I was using a hardware-based 'fakeRAID'. It used to work on my old
OpenSuse install, but that broke and I installed gentoo instead. I
wasn't able to get that to work, and then the motherboard died, so I
built a new system and reused the 3-drive RAID5 array.

Maybe a dumb question, but is the raid45 module enabled in your kernel
config?
Hi all,
I have recently built a new system, running Gentoo on a Sabertooth 990FX
motherboard. The board has a raid controller on which I'm running a
120GB solid state drive for the OS (Raid 0) and a set of three 1.5TB
drives which were previously running as a RAID5 array.
I can see the sda 120GB
