Description of Problem: ckraid.8 manpage exists in the raidtools package, though the ckraid executable has been removed. Version-Release number of selected component (if applicable): raidtools-1.00.2-1.3
it's a manpage for the obsolete ckraid utility. People who have read older documentation might type 'ckraid' - which manpage will explain that this utility no longer exists, and that all such work is now done by the kernel.
