How to use existing ZFS

[Walk3r]

Hy! Today I had a grub bootloader issue.
I managed to reinstall Proxmox 7.1 and now i want to reinstall my existing ZFS.
How do I do that correctly?

Thx

My Partitions:
/dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1

I lost the exact zfs size due to the bootloader issue

zpool list to get the name of your pool. Then zpool import YourPool to import it. You might need to force it with zpool import -f YourPool.

But I hope you got a backup of your boot disks /etc/pve folder or better recent backups of all your guests, because the required LXC/VM config files were stored on your old boot disk.

Sadly I haven't a backup of /etc/pve

Then better regularily backup your most important folders like "/etc", "/root" and "/home" for the future. An you could have backuped your non-bootable PVE installation by booting a PVE Iso into rescue mode or even repairing your grub that way.
