Upgrade from 7 to 8, system can't see boot volume

[gotadmin]

We've performed a number of the upgrades from 7 to 8 without issue, but we have one server where there is a problem. The upgrade seemed to go fine, but when it goes to boot into the 6.x kernel, it cannot see the LVM that has the boot volume on it. The grub loader loads fine. And it can see the storage LVM without issue which is a different disk and I believe a different controller in the system.

If we go into advanced options and boot into the 5.x kernel it sees the boot volume fine and comes up and VMs start.

I do not love the fact that we are running version 8 on a version 7 kernel and would like to see if we can resolve this but I don't know where to start on this.

Anyone have any thoughts on this or seen this before?

Hi,

Could you please post the output of `/etc/fstab`?

Sure thank you!

Also FWIW here is some more data. I should note that the boot in the 6.x kernel can see the raidlvm but it cannot see pve-root
