When ever I try preclearing a newly added drive I get:

Sorry, /dev/sda is already assigned as part of the unRAID array.Clearing will NOT be performed

 

The drive is not part of an array so why am i getting this?

 

 

 

Enter "pre-clear -l" to list candidates.

Enter "pre-clear -l" to list candidates.

basically, it thinks it is assigned.

 

The /dev/sdX letters are assigned each time you reboot,  look in your syslog to see the actual assigned drive letters. It might not be /dev/sda

 

As mentioned,

preclear_disk.sh -l

will show you what it thinks are not being used.

I could not see it as assigned anywhere and even deleted to super.dat file and restarted..... weird...
