Spindown Groups mystically are modified on some drives.

I have a spindown group called "A" defined for all Array discs (+ parity).

This works well.

For some time.

But then, I notice that the last drive of the group never spins down again 😞

You also cannot spindown it anymore even manually (clicking the green dot).

I check the entry and, strangely, the former group name "A" has changed to "Array" for this single drive!

(of course not by me)

Even worse, I cannot correct it with the gui unless I completly stop the array.

This time I have set all drives to the group "X" ("A"->"Array" may be an accident in a script somehow, so lets take somthing that does not show up too often elsewhere). I wonder how long it will last...

Any idea what changes these entries and how to prevent it?
