I'm currently working on shrinking my array, and have been following the instructions in the docs (here) and also shown on Youtube here.
I got to the point of running the clear script, and unfortunately ran into the same issue as this user (wherein the script is not compatible with 6.12+, but the docs have not yet been updated to indicate that).
I then tried to stop the array, so I could re-start it in maintenance mode and follow the instructions shared by this user.
Unfortunately, the array will not stop, because the clear drive script was run improperly (and created /dev/md2, in addition to /dev/md2p1). It's stuck on "Retry unmounting disk share(s)"
Does anyone have advice on how I should proceed? Any help would certainly be appreciated!
