OMV 2.1
had 6 x 4TB drives.
Adaptec controller configured disks as JBOD
Raid running fine.
Then one by one, replaced disks with 8TB - never rebooting NAS in between.
Grew raid, lvm, etc until had to grow filesystem. Found out resize2fs with OMV2.1 (Wheezy) has older resize2fs that doesn't support raid larger than 16TB.
I downloaded Live debian 9 on USB with newer core to use resize2fs on my volume. I restart NAS, miss the boot option it goes back into OMV. However, raid is missing now. /dev/sd[b-g] no longer in dev list.
I reboot again and hit control-A and no JBOD showing up any longer. it looks like adaptec actually does something to disks to make them JBOD.
So I buy a pure 8 port SATA card. replace the adaptec with this SUpermicro card. It only does JBOD. Now when I boot up OMV, I see the drives /dev/sd[b-g], however syslog still says:

What do I do now? Can I force assemble the raid array?
Any help would be appreciated.
