rescue boot PVE6.0, ZFS root

[mosesjohann]

Hi there,

as I made a config mistake my boot ends up with a kernel panic so I'd like to repair the installation (zfs-utils not running correctly so no root file system availible for booting). Thought about booting a buster-iso, chroot and try to fix it but I don't find anything about it to boot rescue mode and mounting existing zfs-pool. May you have hints or already an entry I didn't find how that works?

Thanks!

I tried to figure out and as the Buster-Live iso doesn't know very much about zfsutils from itself including the backports.

So I tried a Ubuntu 19.04 where I had the success to find my pool and can bring it online but just read-only because some requirements for read/write are missing. Would be nice to get knowledge how to do that in case of such a failure and specific: How to do from list of pools, mounting an chroot to the right device. Thanks!

Try using the PVE-iso (start the debug mode of the installer ) - the second debug shell should have all necessary utils installed in a recent version.

(just stop before the actual graphical installer)

I hope this helps!

Was very simple, just had to add
iface eno1 inet dhcp
to /etc/network/interfaces and then
ifup eno1.

Now i could
dkpg --reconfigrure -a
but booting still stuck at

...
Running /scripts/init-premount ... done.
Begin Mounting root file system ... /init: .: line244: can't open ´/scripts/zfs´ : No such file or directory
[ 4.316188] Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000200
...

Any idea why it can Run the premount script but doesn't find the zfs script?

EDIT:

retried to find the error and dpkg says it cant process pve-manager and proxmox-ve because there are dependency problems because there is no systemd - of course not in the chrooted enviroment. as it says scripts get configured with pve-manager so am I stuck here now?

To complete the thread: I reinstalled the system.
