Host down after latest round of updates

[jonc]

I performed a host update but the Web GUI became unresponsive so I restarted the server through the console but now upon startup I get:

GRUB Loading
Welcome to GRUB!
Error: file not found
Entering rescue mode

The server is on the pve no sub repo and doesn't do much (no mods or changes at all) have been made to it but it's obviously alarming that this can occur after an apt-get update.
Does anybody know how I can resolve this?

hi,
you can use to reinstall the grub

this is an almost automatic grub repair.

I got the same error after installing zfs on last node as it comes with special version of grub. It was necessary to boot sytemrescuecd and choose boot from local harddrive or something like that. And after boot run grub-install /dev/sdX and problem was solved.
