I had stablebit scanner start to report errors on one of my pool drives so I thought I'd take proactive measures and replace it prior to failure. I placed a new drive in the pool and then removed the old drive from the pool so it could be pensioned off.
After the removal process I noticed that there were still a lot of files on the removed drive, including the pool information folder. Is this normal? I was expecting the files on the old drive to be migrated off leaving no files behind once the drive was removed from the pool.
