cddl/contrib/opensolaris/cmd/zpool/zpool.8: cddl/contrib/opensolaris/lib/libzfs/common/libzfs_import.c: Add the "zpool labelclear" command. This command can be used to wipe the label data from a drive that is not active in a pool. The optional "-f" argument can be used to treat an exported or foreign vdev as "inactive" thus allowing its label information to be cleared.
