PROTIP - you can run ' screen ' or ' tmux ' from systemrescuecd and have this help text visible while restoring!
============
Full restore instructions: (You may want to print this or copy to text editor, or have it up in a web browser)
You need to have downloaded:
o Proxmox VE ISO installer - https://www.proxmox.com/en/downloads
o Systemrescuecd - https://distrowatch.com/table.php?distribution=systemrescue
o Super Grub Disc (emergency fix boot) - https://distrowatch.com/table.php?distribution=supergrub
o Also handy to have - Rescatux: https://distrowatch.com/table.php?distribution=rescatux
Run the Proxmox installer from ISO / USB and recreate the LVM + ext4 root FS with appropriate disk size
Then, Boot systemrescuecd
cd /tmp
Fire up ' mc ' Midnight Commander
Tab to right pane, Esc+9 (or F9) and SFTP to where your .fsa backup file(s) are
SCP the appropriate restore script (EFI or NO-EFI) over to local /tmp and ' chmod +x ' it
EDIT THIS SCRIPT (look for EDITME) and change the appropriate values to match your restore environnment
Follow the sshfs HOWTO in the comment at the beginning of this script to mount your backup file storage
cd /mnt/restore
/tmp/$0 backupfilename.fsa # Start the restore
After the restore finishes: From here you can still chroot into the /mnt/tmp2 dir and disable zfs imports, edit /etc/fstab, et al
Shutdown, remove rescue media and it should reboot into Proxmox VE
If not, boot Super Grub Disc and that should do it
Once you have a PVE login prompt, you can login as root and reinstall grub
' grub-install /dev/blah '
and then do a test reboot to make sure everything comes up as expected.
