November 23, 20232 yr Hi, My server crashes randomly every once in a while (twice already this month) causing multiple parity checks. This started happening recently even though no new containers or plugins were installed. Attaching diagnostics taken after the last crash. What could be the issue and what is the best way to find the root cause? tower-diagnostics-20231124-0040.zip
December 2, 20232 yr Author Hi, I enabled the syslog server logging to a local cache share (to avoid a lot of writes to the flash drive). Today, a week after, the server crashed again and started a parity checl again. However, the local syslog file doesn't have logs prior to the crash (the last log before the crash was written an hour earlier). Two questions- 1. Is using a local file for the syslog server problematic to catch crash issues? If so, will writing to the flash drive help? 2. Is it safe to stop the parity check? it's the third time over the past 3 weeks the system runs a parity check due to this issue. Edited December 2, 20232 yr by ds123

It usual works fine, make sure it's correctly configured, a lot of users misread the instructions and don't fill in the remote server IP. 14 hours ago, ds123 said: Is it safe to stop the parity check? it's the third time over the past 3 weeks the system runs a parity check due to this issue You can stop it for now but good to run one once this issue is resolved.

December 3, 20232 yr Community Expert If there's nothing relevant logged it usually points to a hardware issue, one thing you can try is to boot the server in safe mode with all docker/VMs disabled, let it run as a basic NAS for a few days, if it still crashes it's likely a hardware problem, if it doesn't start turning on the other services one by one.

What capabilities are affected by switching to safe mode? will the array be inactive? If it's a hardware issue, how to identify the faulty hardware? Edited December 3, 20232 yr by ds123

January 4, 20242 yr Author Hi, I switched to safe mode lasy friday and disabled all docker containers and VMs. About 5 days later, the server crashed. This time the server didn't restart by itself - I found the server off and had to press the power button to start it again. Nothing relevant was logged to the local syslog file, in fact there are no logs from the day the crash occurred. Does this mean it's a hardware problem? What is the next step?
