Heinz:

I was obviously a little confused about a few things when I sent you the email message about updating the LVM manual to document adding and removing stripes from RAID volumes in RHEL 7.4 -- in part I didn't really get that this was part of the RAID reshape feature).  There are bits of information scattered around the LVM manual about resizing, as it turns out -- and no clear explanation of why there is both a "resize" command and an "extend" and "reduce" command. 

But for now the way I addressed this was just to write a summary small section about resizing RAID volumes that just points to othe places, including the information you provided.  It is section 4.4.3.5 here:

http://jenkinscat.gsslab.pnq.redhat.com:8080/job/doc-Red_Hat_Enterprise_Linux-7-Logical_Volume_Manager_Administration%20(html-single)/lastSuccessfulBuild/artifact/tmp/en-US/html-single/index.html#RAID-resize

Could you look that over?  Thanks.

Steven
