Debian Buster: mount raid 0 with no superblocks on boot
I have a OCZ RevoDrive, which is a PCIe SSD that actually consists of some butchered Marvell raid controller with two disks attached to it. As a result, the RevoDrive shows up as two disks
[ 8.198602] oczpcie 0000:06:00.0: Device oczpcie_6_0_0_ssd, model OCZ-REVODRIVE3, firmware revision 2.25, sectors 234441648
[ 8.218591] oczpcie 0000:06:00.0: Device oczpcie_6_0_1_ssd, model OCZ-REVODRIVE3, firmware revision 2.25, sectors 234441648
In order to use the disk one has to know that both devices are actually a raid 0, because (as far as i can tell) there is no raid metadata stored on the disk. I start the raid manually using
mdadm --build /dev/md0 --raid-devices=2 --level=0 /dev/oczpcie_6_0_0_ssd /dev/oczpcie_6_0_1_ssd
My actual problem is that I would like to mount the Windows on that disk automatically at boot time, but I can't make it work. Essentially I don't know how.
I am on Debian Buster. I did set up /etc/mdadm/mdadm.conf with a DEVICE an an ARRAY-line, to use the two oczpcie* disks to build an array /dev/md/windows. However, the mdadm service is masked in systemd and it turns out mdadm is not even a systemd service but an old-school init script /etc/init.d/mdadm, which is used by systemd if and when systemd sees fit. As far as I can tell systemd will start mdadm only if it detects raid superblocks on disks. Unfortunately, there aren't raid superblocks on my OCZ disks. As a result the mdadm init script is never triggered, my mdadm.conf never read and the array never built.
I suppose I could hack a systemd service that is a shell script which does everything I do manually atm, but that seems like a bad approach. How do I make Debian start and mount that array? (I suppose mounting is as trivial as an /etc/fstab entry. My problem most likely is only to get mdadm to start during boot.)
