Just trying out Unraid for a new NAS / VM build but have had some instabilities.

 

Hardware is : Asrock Rack X470DU with Ryzen 3700x, 32Gb EEC memory, 4no. WD Red 2 TB drives (array), 2no. Sabrent 2TB NVME M.2, Sandisk Ultrafit USB 3.1 boot drive

Unraid Version: 6.7.2

 

(Most recent) Symptoms:

System booted 5 days ago, all good, data on array ok etc, checked in occasionally on it (very low usage as been away)

Today:

clicked on various tabs on the UI to check, all seems ok, then 1 processor pins at 100% on dashboard

clicked on VMs tab (no VMs defined yet, wanted to build one)

Headings appear but just wave icon below headings

Click back on Dashboard, hangs, eventually get 504 Gateway timed out.

ssh in, tail /var/log/syslog:

Try 'diagnostics' and it never completes.

ssh in different session, ok, try 'top' nothing showing high cpu

Machine is still up at the moment.

 

Other issues / background: had a very similar issue a week ago, tried to shutdown from shell, shutdown hung at some point, had to power off. When first build machine, had a metal cased USB drive that must have shorted as drive got super hot after seconds, had to get replacement. Had half the cache disappear for no reason during first large data transfer, had to physically power on / off. When I tried to connect my previous server's main sata ssd (in order to image and make VM) server wouldn't boot (wouldn't recognise USB flash drive until sata drive unplugged).

 

Not sure how much of this is related. Do I have dodgy USB flash, dodgy motherboard (can't handle 8+ devices??) any ideas? Why doesn't 'diagnostics' complete?

 

Thanks!!

 

Any thoughts? Thx

I would avoid using USB 3 boot devices. Just get a branded USB 2 flash and use it in a USB 2 socket. I use these because they are small and reliable (you don't need the OTG adapter but they seem to come with them nowadays). You really need to get diagnostics from the server. Instead of trying to ssh in or use the GUI, can you connect a keyboard and monitor and type directly into the console? Do you know what the USB resets and disconnections refer to?

Hmm. Ok, just ordered a USB2 drive, only had USB3 drives lying around. Will see if that fixes it.

Have just tried running diagnostics at the console, same behaviour, just hangs...

I guess it might be because the flash drive has gone walkabout?

I'll try a shutdown, although last time this happened it wouldn't shutdown cleanly...
