Hi Cloudron Community,
unfortunately I had to deal with a full disk space and its consequences.
I was quite stunned that the disk usage was running full so quickly. Without prior notice services stopped and the dashboard was unreachable. After resizing the disk and the partitions I was able to start the server again. Anyways the unbound DNS server wasn't running properly, even though it did after resizing the disk, which caused mainly the mailserver to stop working.
The reason I believe the disk space was running full in the first place:
The mounted CIFS backup volume wasn't mounted anymore → backups were made locally. Why did that happen? No idea. But it would have been good to know that it happened.
These events just showed me that I would miss the possibility to setup email notifications for certain system events, which require immediate action, such as
- Backup volume not found/unmounted;
- Disk usage exceeds a threshold;
- Service X not running since X minutes → indicates a problem;
- … you name it.
And since I read quite often that people’s disk space was running full "suddenly" I thought this might be caused by a lack of information.
