HI! I've recently got a SSD device. Yes, not a disk, but a device. It's called, i. e. one of the first REVODRIVEs. It's a PCI-express card with two embedded ssd disks about ~ 55GB size. And it's a raid card. Fake software raid. You can set it up as a RAID0, RAID1, etc and a CONCATENATION. No way to leave it unconfigured or set it as JBOD or something else. You just won't be able to boot from this device in that case.
So, I tried to install FreeBSD on it. Actually two fbsd version:
FreeBSD 10.3-RELEASE amd64 and FreeBSD-CURRENT amd64 based on r297561
. .
I used RAID0, RAID1 and CONCATENATION raid configurations and UFS and
ZFS (stripe) filesystems. The deivce is seen as raid/r0 and I
installed fbsd on it.
Here is the result of different attemps.
FreeBSD 11-CURRENT r297561 amd64
RAID0
UFS
MBR - during installation I immediately get 'unknown error -559038242'
GPT - the same and 'Error installing partcode on r0p1' message
ZFS
MBR - 'Invalid argument' during installation.
GPT - 'Invalid argument' during installation.
RAID1
UFS
MBR - installs and boots w/o problem
GPT - installs and boots w/o problem
ZFS
MBR - 'Invalid argument' during installation.
GPT - 'Invalid argument' during installation.
CONCATENATION
UFS
MBR - 'unknown error -559038242' during installation
GPT - 'unknown error -559038242' during installation
ZFS
MBR - 'Invalid argument' during installation.
GPT - 'Invalid argument' during installation.
FreeBSD 10.3-RELEASE amd64
RAID0
UFS
MBR - installs and boots w/o problem
GPT - installs, but doesn't boot. I can see on the screen:
gptboot: error lba 1280
gptboot: No /boot/loader on 0:ad(0p2)
gptboot: No /boot/kernel/kernel on 0:ad(0p2)
ZFS
MBR - 'Invalid argument' during installation.
GPT - 'Invalid argument' during installation.
RAID1
UFS
MBR - installs and boots w/o problem
GPT - installs and boots w/o problem
ZFS
MBR - 'Invalid argument' during installation.
GPT - hangs during installation
CONCATENATION
UFS
MBR - installs, but panics during boot
GPT - the same, but also I see the following messages on the
screen durin boot
gpterror 1 lba 234458719
unable to read gpt header
ZFS
MBR - 'Invalid argument' during installation.
GPT - 'Invalid argument' during installation.
Also I've attached dmesg and 'geom disk list' output.
I'm ready to try some patches and help to solve this problem!
