[SOLVED] Proxmox VE 7.4 + Hyper-V + ZFS zpool , command consoles


New Member

I use Proxmox as a virtual machine inside Microsoft Windows 11 Hyper -V . Configuration two virtual disks in ZFS pool . I boot from the installation disk, select advanced mode and "Install Proxmox VE ( Debug mode). With Ctrl + D I get a console, import the pool" zpool import -f -R / mnt" I perform the necessary manipulations and exit through Ctrl + D and again Ctrl + D. After the reboot, I drop out into BusyBox mode with a non-working keyboard and a fallen pool.
1. Why the keyboard does not work.
2. What to do or write in the UEFI line of the bootloader to force the pool to connect.
Thanks to everyone who will respond.

Did you export the pool before you exited the installer? Otherwise, it is marked as dirty.
zpool export rpool

And I removed the "Tutorial" prefix, as this thread is not a tutorial ;)
I cannot say anything about your exact problem, yet I encountered the same "Hyper-V cannot type in busybox problem". It did not work repeatedly, so we restored the VM from backup and it was working ok after that. Not idea why Hyper-V-weirdness is going on there. Linux and Hyper-V is just not a good combination. Hyper-V is great for any MS guest, but Linux is VERY slow and full of strange errors.
И я удалил префикс «Tutorial», так как эта ветка не является учебником
Thanks, I just wanted to describe in this thread how to work with zfs correctly so as not to break the pool structure. So I planned a tutorial...

No, I just made an exit and that's it. I made a cast, so I'll try to restore and make an exit, as you describe.

I believe that there is some tricky solution, that's why I created a branch, in the hope that someone will give the right advice. This is a test system and I want to create a guide for others on how to get around such a problem, so I will look for a solution, not a siding.
