I think the Web UI should inform the operator if
- db is more than 25% of total disc space
- backups consume more than 25% of total disc space
- free disc space in general is less than 20% of total disc space
- before update if free disc space is below say 2 GB
But I dont know where to add this as a feature request.
Reasons is, I had an issue with a HA filling up the stock 32GB the .vdi file for VirtualBox comes with. It crashed, due to no more space on the host, but it was already really close to 32 gb and past 31gb, so its likely it would have run out of space on the running update process. The thing is, the 32gb did fill up in a bunch of weeks, having experience with a FHEM where I had weather and other data stored for since the system was up, and never did grow past 20gb, I was kind of back sided by this HA issue of creating big DBs and therefore at any update a big pre update backup. The result was a total loss of my HA server. So I had to start from scratch minus the learning curve.
To prevent other folks from having the same issue, a headless system should inform when a serious issue is afoot. Almost no free disc space before an update is a serous issue in my view.
Thanks
edit: no I dont want to monitor the host free space, that would be a hacs project or so, but the HA should monitor his own disc space! Windows provides this since the back in the DOS days, if destination is not big enough for the intended data, no installation, no copy. Its so basic, I did never bother to check if HA does supply such an information to the operator. And now I know, no it does not bother to fill up the disc to more than 98%, thats how close I got.
