Remount Pool (btrfs devid "MISSING")?

Featured Replies

How do I remount a non-array pool?

 

I have a non-array pool (btrfs), external hard drive, and accidentally turned the power off to one of the drives in the pool.  I turned the power back on, but the pool doesn't appear to be mounted.

 

Notice the drive is "MISSING":

Stop the array, unassing both pool devices, start the array to reset the pool, stop the array, reassign both pool devices, start array and post the diagnostics.
