=======================================
|
||||
Full restore instructions:
|
||||
|
||||
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 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
|
||||
|
||||
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.

||||
