UNRaid Crashes - 6.7.2

[playisfun60]

Seems Totally Random, cannot access any dockers, ssh, or Web GUI, have to IPMI in and reset server,

 

at one point was happening every day, then for the last 2 weeks no issue, and then again today

 

Seeing this in some of the Logs

Sep 22 14:02:32 NAS kernel: rcu: INFO: rcu_sched self-detected stall on CPU

 

Any Ideas?

 

Thanks

Here are the diagnostics, but this was after the issue and a reboot

Have you done memtest?

[Ancan]

Hit this thread looking for info on the exact same message I got today. For me the shares still seemed to be up, and I could connect via SSH. Web-gui and the hosted VM's was dead though.

 

Haven't done memtest, but plan to. Otherwise I've found out there's some stubborn issues with Ryzen on Linux, which might or might not be fixed by limiting the C-state the CPU is allowed to enter, or completely disable C-states at all. Hopefully a new fresh Linux kernel would help as well, but outlook doesn't look good for that since the latest beta is still on the old 4.19 LTS.

My Spec are as Follows, Issue started up randomly, before never an issue

 

X11SPH-nCTF

Xeon Silver 4114

192GB ECC

8 x 8TB with Dual Parity

2 Samsung 500 GB SSD + 512 ADATA NVME Raid total = 756GB Cache

 

No MemTest as of Yet, could that be an issue, as before this started, I was running UNRAID for over 2 years without any issue?

Still no memtest?

[playisfun60]

Ran for 24 hours no Issue was found, I think it might be related to PLEX docker high CPU Usage, when scanning for media, I have disabled automatic scanning, will see how this goes?

 

Any Other thoughts on causes?

 

Thanks

This turned out to not be the issue, just happened again?

Pls try boot in safe mode first.

 

If no change then suggest remove the NVMe first.
