Symptoms
-
System cannot find the root disk and drops into
an initramfs shell:
mdadm script local-block "CREATE group disk not found"
"Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay=...
- Check root= ...
- Missing modules (cat /proc/modules; ls/dev)
ALERT! UUID=... does not exist. Dropping to a shell!
...

There does not appear to be any workaround so far.
The disks are encrypted SSDs.

failing Artful kernel and earliest known
