BTRFS error (device sdc1): parent transid verify failed on 430581235712 wanted 3932779 found 3932422

This error is fatal, it happens when there are lost writes, i.e. when the controller/device tells the OS all writes were complete when in fact they weren't, usually a device/controller firmware issue, also note that RAID controllers are not recommended and can cause this.

 

Best bet to recover the data is usually btrfs restore, option #2 here:

I know theres no hardware raid, i just didnt setup unraid properly i dont think then or the server when i did this a couple years back, was working fine, So does this mean the Drive itself is toast? I was following step 1, which it mounted and backing up everything as we speak. Once i have a backup just wipe the drive? i had a hard power cutoff prior to this happening (Which i think was the cause of the issue)

That's usually just a filesystem problem, not drive, but because of the controller cannot see SMART for the device.

Once i have backed up the data, whats the easiest way to restore the cache drive back again with the backup to make things go back to normal. (I appreciate the help greatly.) simple MC command and re-write the data back? or anything special needed to be done?

Basically that, make sure docker and VM services are disabled if used.
