Hey all.  I've been running UnRAID for years now.  I recently upgraded to a MSI B760 motherboard and an i5-13500 on my main rig.

 

I took a backup of my flash before I changed equipment.  I got the system to boot with the new hardware... as it should, perfect!  I added two 8TB drives to my already existing four 16TB drives.  Everything good so far... keep going.  I upgraded from 6.9.2 to 6.12.4.  Then I started having stability issues.  Freezes, etc.  Disabled c-states, changed over to ipvlan.  I thought I had her licked.  Get up this AM, can't ping the system again.  Hit the power button on the system and it immediately turns off.  I try to reboot, the system kept going into the BIOS.  I put the Kingston 8GB flash drive into a Windows system.... nothing on it nor can it be formatted.  "No Media" D.O.A.

 

Here's my problem:  with all my troubleshooting for freezes and such, I forgot to take a backup of the flash after I added the two 8TB drives!  Stupid!!

 

I've restored my 6.9.2 to another USB drive. 

 

Issue 1:  I've never transferred a key from one drive to another, so I need to figure that out.  ( I do have my 6.9.2 flash backup )

Issue 2: I don't know what the 8TB drive slot allocations were.  (either Disk 4 or Disk 5)... and I'm scared to start the array with them out of order in fear of corrupting the array.  Can they be out of order?

Issue 3: Should I just create a new USB with 6.12.4?  I do know the parity and cache drive allocations... I just don't have where the 8TBs were.

 

I'm hard down here, I'm a little frazzled, frustrated with the hardware issues and stability problems I'm having.  I can't believe the perfect storm with the flash drive exploding.  I've been in I.T. for over 20 years so of course my wife is giving me the business because I should know what I'm doing....  "Why aren't the security cameras up?  Why isn't Plex working?"

 

Can anyone give me some advice?  64TB array in jeopardy!!

I had to contact support for a new key file... automated key recovery did not work for me.  I followed the doc JorgeB posted to ease my concerns.  I'm back up.  Sorry for freaking out.
