I have / on a nvme SSD and /boot on a RAID10 mdadm array.
After upgrading to 5.0, I get a grub rescue shell (can’t boot).
I tried booting a live CD and reinstalling grub, but it made no change.
Is there anything fundamentally different in the ability for Debian 10 base to read /boot
on RAID10 volume vs previous version of UCS?
At the grub rescue > the ls command shows my four spinning disks and the two msdos
partitions in each. All are listed as unknown filesystem.
UPDATE: The issue may be related to grub not seeing my nmve ssd which contains my /
I’m not sure if this is caused by grub update or OS update. The machine never could boot directly to the NVME due to its age, but it was happily booting from the RAID10 containing /boot and / on the nvme prior to the upgrade to 5.0
