Unraid crashes and must be turned off and back on again

[kelsjon3]

My server every 1-3 days will become inaccessible on the network. I have to power it off and back on again. In this particular case, I can access the Unraid UI, but Docker web pages, e.g. Sonarr and Radarr, are not working. Can someone please help?

Enable the syslog server and post that after a crash.

Thanks for the help! Here's how it's currently setup. What do I have setup incorrectly?

With those settings you should end up with a syslog file in the 'logs' folder on the flash drive.   This will be the one to post after a crash to show what was happening in the lead up to the crash although it is a good idea to post the current diagnostics as well so we can see more about your system.

I hope this is helpful. Normally, the server becomes unresponsive. This time, I could access the UI, but Plex could not be accessed and Radarr's container would not start and displayed an "Execution Error".  I shut down the server, pulled the USB drive and grabbed the syslog. I then turned the server back on and grabbed the Diagnostics. If that's not helpful, I can try again next time it crashes.

 

I do see a lot of errors in the Syslog:

 

Sep  6 05:34:35 Tower kernel: loop: Write error at byte offset 844185600, length 4096.
Sep  6 05:34:35 Tower kernel: I/O error, dev loop2, sector 1648800 op 0x1:(WRITE) flags 0x100000 phys_seg 1 prio class 2
Sep  6 05:34:35 Tower kernel: BTRFS error (device loop2: state EA): bdev /dev/loop2 errs: wr 4414, rd 0, flush 0, corrupt 2, gen 0

 

Then there's this, which is a relatively new development:

 

 

Thanks again.

Cache filesystem has issues, first thing I recommend is to backup and reformat the pool.

I backed-up and replaced the 250GB SSD cache drive with 4 identical 2TB 7200RPM SAS drives in a RAID10. So far, so good. Thanks for the good advice.
