Hi,
I have an issue with my ZFS home server: grub does not load the kernel and stops with a checksum error.
I followed this guide to install the server, and after some attempts I managed to install the system, but it’s now some time that the server can’t boot.
To rescue the system I boot from a Debian live USB, repeat the steps in the guide to access the zfs filesystem in a chroot and do a grub-update, then reboot and the system starts; but at the next reboot the problem is still there and it doesn’t boot.
A bizarre thing is that there are two bpool pools, one of which is I believe a very early (and failed) attempt:
root@debian:~# zpool import
pool: bpool
id: 8990732988331174561
state: UNAVAIL
status: The pool was last accessed by another system.
action: The pool cannot be imported due to damaged devices or data.
see: http://zfsonlinux.org/msg/ZFS-8000-EY
config:
bpool UNAVAIL insufficient replicas
raidz2-0 UNAVAIL insufficient replicas
ata-ST2000DM006-2DM164_Z4ZAMLX9 UNAVAIL corrupted data
ata-ST2000DM008-2FR102_WFL353JL UNAVAIL corrupted data
ata-TOSHIBA_HDWA120_857N5DYKS UNAVAIL corrupted data
sdd UNAVAIL corrupted data
pool: bpool
id: 2278512205360225035
state: DEGRADED
status: The pool was last accessed by another system.
action: The pool can be imported despite missing or damaged devices. The
fault tolerance of the pool may be compromised if imported.

config:

So, does somebody have some idea of what is causing the system to not boot?
Also, how do I get rid of the first bpool? I can’t import because of “invalid vdev configuration”, I can’t destroy it because there are two bpool …
Bye
