Random Shutdown - Not crashing?

-cj- · Apr 20, 2023

System:
TrueNAS Scale 22.12.2 with 12 cores assigned (Host has 48 logical cores, is not busy)
VMWare ESX VM, 64GB ECC assigned, 2x LSI2008 and 2x Mellanox ConnectX5 SR-IOV, 1x VMXNET3, 1x RDMA adapter

This setup was upgraded from TrueNAS CORE, which ran flawlessly without crashes for many years.

I have configured the system to use 50GB of ram for the L2 Cache.

When I login via the web interface, more often than not it will cause a graceful shut down of the VM. When I do this, my SSH session gets terminated and I see the VM going through the shut down stages on the console. I managed to capture some quick outputs before it dropped me from SSH (listed below).

I logged in twice to the UI after the system returned and it shut down twice in a row. It did this the other day as well. It's not consistent. I logged in with a private web browsing window and it did not shut down, but frankly I'm afraid to test the limits without understanding this better.

When it gracefully shuts down, I need to power up the VM again. It doesn't SEEM to be memory related, since I have a considerable amount of available RAM in the VM (7.4GB as per the cut and paste below), not to mention tons of unused swap.

Only thing that stands out is " /bin/sh /etc/init.d/scst stop" process being executed.

Any tips?
Edit: I had to delete a bunch of the processes in the ps aux output since the forum was warning me about 40k+ line limit. I deleted random kernel processes from the output.

Try another web browser. Which browser were you using? What URL are you using to access your TrueNAS server?

Using Safari on the latest MacOS. The URL it's accessing is the hostname and/or hostname/ui/sessions/signin

Both times when it shut down it dropped me into the Dashboard. But I'll keep an eye for any lingering arguments in the URL, but I don't think that's it.

-cj- · Apr 21, 2023

Update: It did it again. This time I was logged in to the UI for about a minute or two, sitting on the "Storage" screen. The WebUI browser was in the background when it shut down. REALLLLLLLY ANNOYING. I wonder if there's a way to break the shut down sequence temporarily?

Edit: Or better yet, any way to increase the logging to find out what's happening? I've combed through the /var/log logs and nothing indicates that there's an issue or what's triggering the shutdown.

I've seen hard-to-debug shutdown issues caused by flaky keyboards randomly spewing the ACPI shutdown code. How is your VM configured, USB-wise?

Thanks for the reply. Honestly, nothing special - Same general VM setup as my other Linux VMs. I've attached screen shots below, but nothing stands out. In fact this last time I wasn't even doing anything on TrueNAS after logging in and going to the "Storage" tab. I switched to another window and a minute or so later I noticed it was shutting down. I also made sure I didn't have any weird arguments in the URI.

The only thing that's "weird" about this VM is that my fd0 device gets accessed. I'm not even passing it to the VM, but I've been meaning to disable it. There aren't any fd0 errors around the time TrueNAS shuts down, so I dont think it's related.

Edit: Just to disclose everything I'm doing, I ssh into TrueNAS as my admin account, I issue "su -", and I monitor my zpool status since I'm currently resilvering a drive that's been giving me an issue on a Z2 pool. I open a browser window to TrueNAS and immediately try to get out of the Dashboard screen since that's where shutdowns usually occur. This last time I clicked on "Storage" and moved away to another browser window. When it shuts down I either notice because the UI says that it's waiting for the controller to come up or I notice my SSH session being terminated in my terminal window.

So far, I haven't had one of these shut downs occur when I'm using a private browser window, so I'm going to see if that continues to be the case.. But I'm scared to use the UI at this point!

(Sorry for all the details)

Try a different web browser to help isolate the issue.

Good idea. I'm using Edge for now and so far it isn't triggering a shut down. Safari has been consistently shutting down TrueNAS for whatever reason. Will update.

Important Announcement for the TrueNAS Community.
