[atlas] anchor disk recovery

Hi, after a power outage, our anchor got its grub.cfg file corrupted. I managed to use a .rpmsave boot.cfg that was present on the disk and boot into the recovery kernel.

From here the anchor is alive again on the management interface at https://atlas.ripe.net/probes/7000/ but I guess it's still in a unstable state.

What is the procedure to actually repair the installation ? Should I re-install it from the USB image, or is there something else I can do remotely ? x -- Matthieu Herrb
