annotations.description = ''The root disk of {{ $labels.alias }} has {{ $value | printf "%.2f" }}% free disk space (Threshold at ${disk_free_threshold}%). CI for deploying new configuration will seize working. Log in to the system and try to clean up the obsolete files on the machine. There are a couple of things you can do:
1. `nix-collect-garbage -d`
2. clean up the shack share folder in `/home/share`
3. check `du -hs /var/ | sort -h`.
4. run `docker system prune`
5. `find /var/lib/containers/news/var/lib/htgen-go/items -mtime +7 -delete;` to clean up the link shortener data
5. If you are really desperate run `du -hs / | sort -h` and go through the folders recursively until you've found something to delete
6. as a last resort the root disk can be expanded via `lvresize -L +10G /dev/pool/root && btrfs filesystem resize max /` '';
