i had a drive that had a damaged filesystem.
also it was a small 250 GB drive.
so i cloned the drive and partions because it was also the OS drive and i didn't want to re-install.
everything seems to be running like it should but looking a partion that i've added to the pool it shows the drive i've removed.
This screenshot shows the drive that actually is removed
here a screenshot of the drive that i've cloned
but i can't add it to the pool because it says it's the same drive
I tried the troubleshoot tool
and tried the following options
restore drivepool shares and did a reboot.
but still no changes.
i was thinking perhaps i should remove the ghost drive,
then reboot and hope it fixes the problem.
and i would be able to add the bigger partion of the cloned drive
