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.
