[linux-lvm] lvextend docmentation vs. implementation (lvm2-2.02.39), Suse-11.1

[Linda A. Walsh]

I have been trying to use the lvextend command using the documented
size format:  of +[number][%{LV|PV|VG|FREE}] --
specifically
+50%LV.

tried multiple variations on LV -- no luck.  Is this broken or
is this just not working in my setup, or am I doing something
wrong?  It fails with:
Invalid argument +5%LV
Error during parsing of command line.

Advice?
thanks,
-linda

The %age features are part of the -l switch, so the command line would 
be something like:

# lvextend -l30%VG storage/lvol0

That worked for ma anyway. If it still doesn't work your LVM tools might 
be too old

    You'd need to send the WHOLE command line you used
in order for us debug it for you, not just a couple of
characters from it.  That is, however, enough to see
a couple of problems you have.  This document may help
you solve two of your problems:

    I'm also going to guess that you tried throwing
"+5%LV" out there in the middle of the command line
rather than as the argument to -l.  The man
page says:

{
   -l/--extents   [+]LogicalExtentsNumber[%{VG|LV|PVS|FREE}]  |
   -L/--size [+]LogicalVolumeSize[kKmMgGtT]
}

    Sorry -- I was using it with capital "L" not lower case...didn't know
there were two separate switches... my bad.
thanks,

The implementation of the feature turned out simpler with -l than with -L.
(Because sizes supplied with -L require conversion to 'natural units'
of extents which may involve rounding.)
