Unraid server hanging, unresponsive till hard reset

Featured Replies

I've had this issue for a while, but it's getting more worse by the week.

My server randomly freezes from time to time, everything becomes unresposive and the only thing to do is hard reset the system.

 

Even the console on the machine itself doesn't respond.

 

Now the issue has been going on with my old hardware and new hardware. I've recently swapped motherboard & cpu since I wanted more PCIe slots and a newer CPU. But the issues persists.

 

I've enabled syslog and checked the logs.. but I have no clue what is causing it.

These are the logs after todays crash. Hence I enabled syslog, and then it happened ~3 hours alter again.

It the persistent syslog complete? It only cover 3 hours uptime and all entries are about proxmox-backup-proxy[10]

That's the file I found on the location I have it logged.

The backup proxy is a docker container I run to backup data from my proxmox nuc.

I can try disabling the container and check for stability.

 

Edit:
I mirrored the syslog to flash, this has more info appearently.

And the diags.

Jan  2 19:46:27 ZonarrServer kernel: macvlan_broadcast+0x10a/0x150 [macvlan]
Jan  2 19:46:27 ZonarrServer kernel: ? _raw_spin_unlock+0x14/0x29
Jan  2 19:46:27 ZonarrServer kernel: macvlan_process_broadcast+0xbc/0x12f [macvlan]

Macvlan call traces will usually end up crashing the server, switching to ipvlan should fix it (Settings -> Docker Settings -> Docker custom network type -> ipvlan (advanced view must be enabled, top right)), then reboot.

I've applied the settings, let's see what will happen in the next few days. :)

Don't forget to reboot.

That was part of my application ;)

Unfortunately there's nothing relevant logged this time, 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.

So an update on my side.. I think I found the problem, server has stopped crashing.

 

As suggested I've disabled ALL of my dockers. Left on 5-6 ones, and started turning one them one by one with 2 days in between. Turns out my Home Assistant Docker just crashes the whole server. I've left it disabled, booted the other dockers back and all seems to be good to go again.
