How reproducible:

Comment 1 Corey Marthaler 2007-08-06 21:58:33 UTC
It appears that this blank spot is where the "New Volume Group" is supposed to
be, as I can't seem to find a "New Volume Group" icon anymore. This appears to
be a regression.

Comment 2 Corey Marthaler 2007-08-06 22:07:18 UTC
Nope, apparently the pvs I had were added to the root volume group, which I
wasn't aware would happen when I created them, so now that I have no pvs
available, the create a new vg task is missing, which is yet another example of
bz 251052 and how removing tasks gets confusing. :( 

Ended up fixing my issue by hand.

This bz remains a bug, but not a regression.

fix verified in luci-0.10.0-4.el5/ricci-0.10.0-4.el5
