I have a drive that appears to be bad in unraid (4.7).  I have pulled the drive - and it appears to test good.  Ran it through seatools - pass.  Did all the smartchecks - pass.  I even deleted the partition on the drive, created a new one in Windows and formatted the drive.

 

I know installing a new drive will work - but I had to go out and buy another drive when this one appears to be fine.  How can I get unraid to use this drive again.  Even after formatting and putting the drive back - it still marks it with the red ball.

 

Any ideas?

 

Thank you

 

Found the solution  - sorry for wasting anyone's time.

 

How do I re-enable the drive?

Okay, the cable was loose, or I think the failure was a fluke - how can I get unRAID to reuse this same disk that it thought had failed?

If you are sure that the drive is fine, and the SMART report confirms it, and you have not written to the drive since it was taken off-line, then use the Trust My Array procedure, to quickly recover your drive and the array to an all green condition. Remember, it was taken out of service when a "write" to it failed so using the "trust" procedure will effectively forget the data written while the drive was disabled. Unless you are certain you have not written to the disk a reconstruction is much better. The safest option is to reconstruct the drive. Only use the Trust procedure if a reconstruction is not possible.

You can re-enable the hard drive and reconstruct it as follows:

Stop the array.

Go to the Devices page and un-assign the disk.

Go to the main page and start the array.

Stop the array again.

Go to the Devices page and re-assign the disk.

Go to the Main page - system should indicate there is a "new" drive to replace the disabled one. Check the confirmation box and click Start to start a parity-reconstruct of the disk.

stop the array

un-assign the red-ball-drive

start the array with it un-assigned (this will cause unRAID to forget its model/serial number)

stop the array once more

re-assign the drive (it will think it is a replacement for the missing drive and will re-construct onto it when you re-start the array)

start the array.

 

The drive turned "red" when a 'write to it failed, therefore its contents are guaranteed to be incorrect.  unRAID must re-construct it.

 

You did not need to format the disk, and in fact should never format a disk outside of unRAID's management console...    When re-constructing onto the disk it will take care of the formatting for you.
