[SOLVED] Proxmox crashes at each boot

[RudyBzh]

Hi,
A few minutes/hours after a fresh install using Proxmox installer (OS on single drive using ZFS) and some tunings, like network (bond creation and jumbo frame for example), I made « apply network config » (needs ifconfig2 or something like that), and proxmox crashes. I had to reset computer.
Since that, I’m not anymore capable to boot it… It crashes each time at the state you can see in attached picture.
Any idea of what it could be please ?
It’s as if my network config makes it crashes each time ? (Bug about jumbo frame ?!?)
Will try to « rescue » through installer, but I don’t think it’s a default behavior…
Thanks a lot.
2nd picture is a reset later and a crash at the same state.

Well, successfully recover

Boot from usb key installer => install terminal (debug)

Once here, I could get in a bash (after exiting from grub or something like that)

Next Had to import my zfs pool rpool
If you do : « zfs import rpool »
You have a message saying you can’t because it was already imported in other OS
You can force it : « zfs import rpool -f »
But doing so, I was not able to get in « / » because already mounted by USB OS (mountpoint conflict)
So you have to import pool this way : « zfs import rpool -f -R /mnt »
See here

Finally, I could edit my /mnt/etc/network/interfaces to remove all my settings (previously set through proxmox GUI)

Don’t forget to export your zfs pool (« zfs export rpool ») before exiting/rebooting if you want your next boot to be able to import it without a lock needing to use import -f

My boot was normal after setting standard interface settings.

Now, have to understand why my previous network config was able to put Proxmox in such a locking state !?!?
