My unRAID server froze up overnight.  I rebooted and it wouldn't recognize my USB drive.  I reformatted the USB drive using the latest unRAID installer.

 

Now the server boots, but my array configuration and all my data seem to be missing.

 

I had dual parity drives and I'm not sure which drives were part of the parity and which were part of the array.  Additionally, I had 4 SSDs in a cache configuration and 2 NVME drives in a second NVME only array to use for my Docker storage.  I've been running in this configuration for months and just upgraded to 6.12.14 last week.

 

After booting from the new drive, everything is missing, including my root password configuration.  It's like this system was never configured to run unRAID.

 

After unlocking my drives through the command line, I collected this information:

I recreated my array layout to the best of my ability using that information.

 

How safe am I to start the array at this point?  Will I still have my network/docker/etc configuration when I start up again?  I have a new ticket open, but I was hoping to get some community guidance.  I plan on ordering a new USB drive to replace my SanDisk Cruzer that failed, but I'm just trying to get back up and running for now.

 

Thanks,

Doug

did you make a flash backup? if so grab the config folder and copy it to the flash drive.

since you reformated the device and didn't keep the config data. your disk setting are gone. You will need to set the FS to auto and read the disk and remake and pool devices.
 

Since the disks were using zfs easy to see where each one goes where, except parity, but you have a 50/50 change of getting it right, if you miss, you will just need to re-sync parity.
