Two accounts of lock ups (diags included

[Ulf Thomas Johansen]

Hi.

 

System has been running stable for many months now, and over the last two weeks I've had two lock ups. As I am running headless I cannot see any core messages on the screen, but after last lock-up I mirrored syslog to the usb drive. I do fear a hardware issue and would appreciate any help in nailing it down.

Regards

Nothing relevant logged in the previous syslog that I can see, but it ended in a way that suggest it could have been full:

 

Dec 13 10:51:39 Algarheim kernel: mdcmd (317): set md_write_method 1
Dec 13 10:51:39 Algarheim kernel: 

 

Post new diags after the next crash, also if possible stop the SSH spam in the log, even if just temporarily, it may fill it up before the crash.

Thanks. I have changed the ssh config (some remnants of an old debug session I presume) - and will patiently await the next failure.

 

Is there anyway to extend the log?

Not that I know of.

Thanks.

Well that didn't take long:

 

These are the last lines of the syslog:

Unfortunately there's nothing relevant logged, this 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.
