I have got the message "Kernal Panic", after turning my ReadyNAS NV+ v1 back on, and have read the threads about checking disks etc.
But I cannot do this until I have managed to turn the NAS off safely, and the power button isn't doing this. Will it be still checking through the arrays? Do I have to do this? The other threads say not to hot swap in this situation so would like to do a proper shut down before removing drives to check they are ok.
You cannot update the firmware without disks inside the NAS. Since all four drives passed the extended test, you may insert all four drives and check if the NAS boots up just fine. Check if you can still access the data stored in it. Then observe, if the Kernel Panic message appears again.
Also, if you are able to access the data stored in your NAS, the first thing to do is to make sure to back up all of it right away for safety.
How do i perform a memory test without rebooting so that I can hold the power button down for 25s to do memory test - hence the main question - how do I restart a NAS that wont power down?
Since they are now part of western digital, you could also try WDC's lifeguard software. Even if it doesn't recognize the drive, you should still be able to run the long generic test.
Hmmm, when I put a drive in a caddy and connect it to my PC the computer recognises the USB connection, but does not recognise the drive. I ran WinDFT, which I got from the HGST site, but it couldn't find the drive either.

Memory chek was fine - individual disk checks were fine, and then, when I re-installed the drives the NAS started up fine. did a re-sync and it looks like Disk 2 is on its way out - up to 370 errors now I think. but I'm back up and running, and I have updated my backup since the re-sync -so all okay now.
Thank you everyone for your help.
Just to summarise:
On Kernal Panic
1. NAS wouldn't shut down so had to pull plug.
2. removed all drives and did a memory check by holding power button until the memory check option showed.
3. used LifeGuard to perform extended check on each drive (~8hrs per 1TB drive)
4. Reinstalled all drives in correct order and started NAS up
5. Performed re-cync on volume
6. Made sure my back up of the data was up to date!
