Okay, Bigger problem now.

 

I decided to just start the rebuild. When I started the rebuild, unraid instantly spat out that parity 2 had an error and now the status shows that "Parity device is disabled".

 

I checked it, it was a SMART error UDMA CRC error count with error value of 8. I read the forums, replugged everything in, clicked the error icon so that it looks healthy now, but the parity drive is still disabled. The error count hasn't gone any higher

 

It looks like I can still see all of my data, I'm backing it up now... but is there a way to fix this???  

 

Rebuilding parity is throwing out a lot of errors, but it seems I can still access most if not all of my data.

 

I've attached the diagnostics below. 

 

 

 

 

 

 

------ original post --------------

I'm upgrading my backup server with new hardware to be my new main server. I forgot to backup homeassistant before unplugging everything and swapping out the power supply. Long story short, I ran out of SATA power, but I just needed to get the backup and impatience got the better of me since amazon said it was gonna take 2 days for the splitter to get here. I booted the system up, started the array, started VM (VM share is only on nvme cache pool and not on array so I thought no data would be written to array). I shutdown everything after I got the backup.

 

Now that I have the sata splitters cables, when I power on all the drives, it shows the 2 drives I previously didn't plug in as "new devices" when I add them to the array ( forgot to take a picture of previous drive config... I know stupid. I wouldn't have done the psu swap if I didn't know I couldn't run the two serves at the same time).

 

Any way to re-integrate them into parity without rebuilding both drives? My server is setup with 2 parity drives with the new server with 98% backed up. I'm guessing I'll probably have to rebuild parity, but I'm just hoping to avoid if possible.

 

Thanks for any help

Updating situation

You have 3 invalid disks, so that won't work even with dual parity, if you think disks 11 and 12 are good you can do a new config and check "parity is already valid", then run a parity check and post new diags if there are more issues.
