[linux-lvm] pvscan: bugs in manpage and implementation

[Tom Hale]

Hi,

MAN PAGE

In http://man7.org/linux/man-pages/man8/pvscan.8.html I see the
following issues:

* The string "-a--activate" appears several times. Should be:
  "-a|--activate"

* "-a|--activate y|n|ay" is mentioned, but later on:
"Only ay is applicable." Please remove "y|n|".

PROGRAM

# pvscan --activate ay
  Command does not accept option: --activate ay.

The message is confusing. It would be better to say "--activate requires
--cache"

In fact, why not drop the "ay" argument all together and just allow
"--cache --activate"?

Cheers,
Tom
