DIAGNOSTICS
       All  tools return a status code of zero on success or non-zero on fail-
       ure.  Non-zero exit codes may change and should not be assumed to imply
       specific errors.

Comment 1 Jonathan Earl Brassow 2016-08-31 21:21:27 UTC 
agk, can you look over the proposed change above?  If you are happy with it, let's check it in.  It should prevent other users from assuming exit values mean specific things.

Comment 4 Corey Marthaler 2016-09-08 15:57:47 UTC 
Verified new warning about the dynamic nature of exit codes/messages:


3.10.0-501.el7.x86_64
lvm2-2.02.165-1.el7    BUILT: Wed Sep  7 11:04:22 CDT 2016


DIAGNOSTICS
       All  tools  return a status code of zero on success or non-zero on failure.  The non-zero codes distinguish only between the broad categories of unrecognised commands, problems processing the
       command line arguments and any other failures.  As LVM remains under active development, the code used in a specific case occasionally changes between releases.  Message text may also change.
