[Support]: Frigate causes read only errors and unresponsive Home Assistant server after several hours of running, power cycle required to recover.

Describe the problem you are having

Home Assistant runs fine for days without Frigate running but if I start Frigate, at first, everything looks fine, all cameras are running fine but after several hours, the whole system becomes unresponsive and the console screen is constantly scrolling with errors like “systemd-journald[114]: failed to write entry (9 items, 332 bytes), ignoring: read only file system”. The only way to get control back is to pull the power.

At first I thought my SSD had failed, so I installed a brand new SSD and restored HA. Everything came back up ok but I stopped Frigate initially to keep overhead down, that’s when I discovered that its running Frigate that causes this problem.

Another issue I have noticed is that despite having Frigate set to not start on boot, it ignores this switch and starts anyway. To keep my system running smoothly, when my Pi is powered up, I have to wait for Frigate to start by monitoring the log screen and the click the stop link once that appears on the add-on screen.

I have seen these types of issues with disks being power related. The OS drops them into read only mode when it has issues writing. Are you using an externally powered USB hub?
