CentOS - May 2013 - Kickstart and volume group with a dash in the name

Hi,
I'm trying to setup the provisioning of new OpenStack hypervisors with 
cinder volumes on them. The problem is that kickstart doesn't allow 
dashed in volume group names?
I tried this:

volgroup cinder-volumes --pesize=4096 pv.02

and this:

volgroup cinder--volumes --pesize=4096 pv.02

but in both cases I end up with a volume group named "cindervolumes"
on
the system. Any idea what I have to do to accomplish this?
Defining VGs with dashes works perfectly fine on the command line.

Regards,
   Denis

Hi Dennis

Did you try to screen it via "\" ? i.e. "volgroup cinder\-volumes
--pesize=4096 pv.02" ?

Since LVs can be referenced in a way that contains dashes, I expect dashes
may not be allowed.

See these examples:
/dev/vgname/logvolname
/dev/mapper/vgname-logvolname

But the following excerpt from "man lvm" doesn't support my
thought.

VALID NAMES
       The following characters are valid for VG and LV names: a-z A-Z 0-9
+ _ . -

       VG  and LV names cannot begin with a hyphen.  There are also various
reserved names that are used internally by lvm that can not be used as
       LV or VG names.  A VG cannot be called anything that exists in /dev/
at the time of creation, nor can it be called '.' or '..'.  A LV
can?
       not  be  called  '.'  '..'  'snapshot'  or 
'pvmove'. The LV name
may also not contain the strings '_mlog', '_mimage',
'_rimage', '_tdata',
       '_tmeta'.

Underscores work just fine.
You might consider using underscores instead of dashes.

As maxxik suggests, you may consider escaping the hypen/dash.

If you have commands that work on the command line,
try adding them to the post install section of the kickstart file.

It seems so.

https://bugzilla.redhat.com/show_bug.cgi?id=186439
https://bugzilla.redhat.com/show_bug.cgi?id=407701
https://bugzilla.redhat.com/show_bug.cgi?id=430907
http://rhn.redhat.com/errata/RHBA-2009-0164.html

If I understand it correct then it should have been fixed long ago. I tried it.

CentOS 5 does *not* strip the dash
Fedora 18 does *not* strip the dash
but
CentOS 6 *does strip* the dash

It seems like a regression. You are using CentOS 6, aren't you?
Would you mind filing a bugzilla?
