Also just by the way, 'vos zap -force' is not a very smart tool, and it
usually doesn't make a lot of sense for non-RW volumes. For RO and BK
volumes, all it does is remove a few header files without touching any
of the data, which is not what you want to do.

If you have a troublesome non-RW volume, and 'vos remove/zap' and
salvaging does not help, my general advice is just to stop right there
(don't do 'vos zap -force'). Those two should handle every possible
case, so if they are not handling it then there's a bug. Trying more
things might make things worse or lose valuable debugging information.
