Kernal PAnic - how to turn NAS off?
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 ...
Hi nrobinson1,
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.

So am I right in saying next step is to check each of the disks with manufactuers software? They are hitachi drives HDS7210DLE630.
Yes, Their drive fitness test link is https://www.hgst.com/support/hard-drive-support/downloads
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.
Am I doing something wrong?

The PC should see the drive, but can't mount it because it doesn't support the format.
Try opening the disk manager (for win7 that is done by right-clicking on computer and choosing "manage") and see if the drive shows up there.
If it does, try lifeguard instead of WinDFT.
If it doesn't, try another drive - just in case the first one has failed.
Thank you Stephe, that has worked, Life Guard is now scanning the first drive...
I'll let you know what the results are when I have done all for - I may be sime time...
So all four drives have passed the LifeGuard disk extended test.
Do I trry reinstalling all four drives or do I justt install 3 at a ime and see if it boots?
-234, then 1-34, then 12-4, then 123- doing a proper shut down between each?
Or seeing as they all passed okay do I re-try installing all four?
Should I try to update the NV+ firmwear before I put the disks back?
Thanks for your continued help and input!
Nik.

Thanks everyone - this seems to have worked.
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!
Thanks once again - Nik.
