Second "unscheduled reboot" in 4 days, all since upgrading to TrueNAS-12.0-U2.1

[pnunn]

Now, this could be a hardware issue, but if it is, its the greatest coincidence in history.

This machine has been running fine for about 12 months now, and this is the first time I've had reboots.

This time it took all of the VM's with it as the NFS crashed and I needed to reboot everything again to get it all back this morning (luckily this setup isn't in a DC miles away).
It seems the 10GB networking wasn't happy after its own reboot in the early hours this morning.

Where do I start looking for evidence of problems?

Does your system reboot or hang/freeze?
I have a freezing-issue with two systems since updating to 12.0-U1 - which also could be a coincidental hardware issue!

Interesting... This machine rebooted both times, however the second time, despite being alive in terms of web interface and gui, the 10 GB Nic wouldn't work (I think) so I had to reboot it again to get everything working again.

I think you need to tell us something about your machine and its setup if you are really looking for help here. "Forum Rules" in the masthead will give you some ideas on expected information.

 

[pnunn]

Yep.. your right @Redcoat. Here goes (and it rebooted again yesterday grrr)...

The box is a Dell R520.
32GB Ram
5 x SEAGATE ST600MM0006,
2 x TOSHIBA AL12SEB600
1 x SSD for the boot volume

One Pool in Z2 giving 2.86 TB.
HBA is an IT mode H310 mini mono.

1GB Nics, dell nics.
10GB Nics Chelsio (not sure of the model). Running Twinax


Issues have only started since upgrade to 12.0-U2.1

Not sure what else I can tell you.

 

[pnunn]

And again last night....

I run an R520(see sig below) the only thing i could think of would be the nic(possibly a driver problem). Try getting an intel 10 gig nic..see if the problems persist.

 

[pnunn]

Hi @hescominsoon, this has been running stably for quite some time before the last upgrade. Not sure its a driver issue. I'm not sure where to even start looking though which is part of the problem.

An intel card is cheap especially given the symptom you had with the nic not responding. You have to start somewhere...:)

 

[pnunn]

Sigh.. and two more today.

I'm starting to think its relate to the load on the server. Today's were both when I was trying to spin up 5 vm's at the same time.

Are there any logs at all that might give me a clue?

 

[hescominsoon]

restarts like this are a hardware/driver problem. either roll back to the previous install(unless you deleted it) or change the nic out...i would change the nic out given your symptom earlier. However if you still have the previous install on your boot disk roll back to that and try it again. If you still restart then you have maybe a cpu cooling issue, or PSU issue, or something like that.

 

[pnunn]

Ahh.. OK. Didn't realize I could roll back a release. I'll give that a go first. As I said at the start, I'm quite up for the fact it could be hardware, but the coincidence is pretty good if it is :) Thanks @hescominsoon

 

[hescominsoon]

if things work fine after the rollback..then replace your nic with an intel..you probably have a driver issue with the current nic in TNC12.x.
