[Bug 2047173] Re: grub-probe: error: compression algorithm inherit not supported

[James Dingwall]

I have experienced this today on an Ubuntu 22.04 system.  When I try to
ls the bpool from the grub command line:

error: compression algorithm inherit not supported

The bpool is mirrored on 2 nvme partitions, same behaviour for both.

Now worried about restarting other servers which have a similar disk
layout.  I had an uptime of about a month and a pending reboot for a
kernel upgrade.  If I can rescue the system I can check apt logs to see
what has been updated.

Title:
  grub-probe: error: compression algorithm inherit not supported

Status in grub2 package in Ubuntu:
  Won't Fix

Bug description:
  I've reinstalled several times already, .. sometimes it works for a
  while sometimes the issue is there instantaneously, but grub can't see
  uuid of zfs file systems.

  When I boot live I can import them just fine, can't boot the system as
  grub marks them as unknown filesystems.
