[Device is disabled - what now?]

Thanks JorgeB, I'll test the cables by swapping out.  Is it possible under these circumstances to rebuild onto a new disk instead of onto itself?

[Device is disabled - what now?]

I restarted my UnRaid 6.9.2. system a week or two ago after months of being turned off (for non-technical reasons).  It was fine for a bit but then I got "device is disabled" on disk 3.   I thought it might be cables or my disk.  I downloaded diagnostics, powered down, checked cables (they seem OK) then powered up again.  It's still disabled.  I reran diagnostics.  As far as I can tell the SMART data is OK.  Diagnostics from before and after power down are attached.

 

What do I do to get disk3 out of its disabled state?  I have a new disk ready to go if it's needed - in fact if appropriate I'd rather rebuild onto the new disk - I need to add some extra space to my array anyway, and the new disk is 10Tb as opposed to disk3 which is 6Tb.

 

Thanks as always for your help.

[New Mobo, Unraid now won't boot SOLVED]

OK, I found a solution, although it might have been a bit clunky. I'll put it here in case it helps someone else.   I'm pretty sure it was the uefi issue that got me. 

 

So to fix it I backed up my old  UnRaid USB stick onto my laptop, then used the install tool to install the current version of UnRaid onto my USB, and copied my licence key back into the config folder.  This meant a fresh start - I deliberately didn't attempt to copy over my old config settings.  They were a bit of a mess anyway.

 

After that I just added one of my old data drives to the array, plus a new bigger one and am currently using MC to move data from the old drive to the new.  I'll repeat until I've got all my data onto my new drives (I decided to just add one at a time, rather than risk screwing up multiple drives if I stuffed something up).  I'm aware I'm unprotected until I'm done and have added parity, but I can live with that.

[New Mobo, Unraid now won't boot SOLVED]

Thanks for the quick response ChatNoir. I'm guessing I was booting in legacy BIOS.  Old Mobo was ASROCK rack c2750d4i.  The ASROCK product page for it doesn't mention UEFI anywhere.  New mobo is ASROCK B560 Mini-ITX.  My flashdrive doesn't have an EFI- folder.  I'm thinking upgrading my UnRaid is probably a good idea, but I'm not sure if I should do it now or after I've solved this problem.  Further guidance would be appreciated.

[New Mobo, Unraid now won't boot SOLVED]

Hi all, after moving house a while back my Unraid 6.1.9 setup refused to boot (it didn't even post, totally dead).  Some research later and it was a known fault with my mobo.  So I've replaced the mobo, cpu and ram.  It now posts and goes into BIOS fine, but won't boot from my Unraid USB (it boots from a new Kubuntu USB OK).  The BIOS lists Unraid as the only boot option but refuses to boot from it (my data drives are currently disconnected).

As far as I know nothing's changed with the contents of my Unraid USB (I hope).  Can someone give me help with what to try next?  Recreate Unraid on the existing USB and copy my config folder across?  Start with a new USB?  something else altogether? Thanks for your help.
