    Today our cloudron instance (on a hetzner dedicated machine) became unresponsive, both to web and ssh requests

    Power cycling did not help. Booting into recovery mode, the last lines of the box.log are as follows:

    Any idea how we can further troubleshoot?

        Finally got things working again after taking the following steps:

        1. Asking Hetzner to replace the machine (not drives) - although this didn't fix the issue, and may have been unnecessary

        2. Opening the rescue system and running fsck -fy /dev/md2 per this guide: https://docs.hetzner.com/robot/dedicated-server/troubleshooting/filesystem-check

        This seemed to fix a load of disk issues and now everything is running fine.
