Detaching Submirror With metadetach Command Automatically Resizes Mirror (4678627)

If you use the metadetach command to remove a submirror from a mirror, you might not be able to reattach the submirror. This problem occurs because the mirror is automatically resized after you detach the submirror.

Workaround: Before you use the metadetach command to detach a submirror, attach a submirror of equal size to the submirror you want to detach.
