screenshot of grub errors

If a raid 1 lvm volume is configure with raidintegrity enable, grub is unable
to boot with the error: "unknown node 'root_rimage_0'"

Reproducer:

Install tumbleweed in a VM with LVM for root + swap.

Resize the VM disk to allow space for the integrity image.

Add another virtual disk of the same size.

copy the partition table from vda to vdb
# sgdisk -R /dev/vdb /dev/vda

reset vdb's GUID
# sgdisk -G /dev/vdb

Create a PV on vdb2
# pvcreate /dev/vdb2

Add vdb2 to the vg
#vgextend system /dev/vdb2

Convert the root lv to raid 1
# lvconvert --type raid1 system/root

wait for the sync to complete
# lvs -a -o +devices

Reboot to demonstrate that raid1 is bootable.
# reboot

Add raidintegrity
# lvconvert --raidintegrity y system/root
