anaconda fails to logical volumes not in /dev/VolGroup00

Description of problem:
With boot images using kernel-2.6.20-1.2962.fc7 anaconda
does see that there are two volume groups with file systems
to mount but after mounting volumes from the first group
it bails out with
22:14:20 DEBUG : isys.py:mount()- going to mount /dev/VolGroup01/LogVol00 on
22:14:20 ERROR : 0
and does not even try remainig ones. After that in /dev/mapper/
one can find only volues which already got mounted so remaining
ones are inaccessible. It does not matter if selinux is active.
Version-Release number of selected component (if applicable):

What filesystem type are the volumes that aren't mounting?

All these happen to be ext3. BTW - anaconda from FC6 does see
filesystems from multiple volume groups although I will have
to repeat that experiment with the same system on which I got
I tried anaconda from FC6 and the same system. All file systems
which should be mounted are mounted even if an "error" notification
pops out. I think that the last thing happens because from logs
it looks like that anaconda attempts to create various mount
points which already exist in already mounted filesystems
(like, say, /boot). In any case I asked for mounts read-only.
One more observation (although this was with 18.104.22.168). If
after a failed mount of logical volumes I will do
lvm vgchange -a y
then missing entries in /dev/ do show up and I can now mount
all remaining ext3 file systems.
We do an vgchange -an after the failure, so I'd expect them to be unavailable
there. I'm wondering if this is (somehow) related to the ext2 support dropping

If an error on some file system is forcing a dropout of all other
outstanding mounts that would be conceivable although surprising
in a concept.
Note that if after mount failures I will peek into
/dev/mapper/ then I do not see any entries for all those MIAs.
Following that with 'lvm vgchange -a y' fills out /dev/ as
expected and now I can mount all these file systems - either
using '/dev/....' or by label (with /mnt/sysimage/bin/mount
and if a label is present).
Again - anaconda from FC6 is somehow able to cope without
a "helping hand".
Re comment #6. I did try (another system, but I rigged something
similar) with bug 230946 fixed on new images. ext2 filesystem indeed
mounted fine but I got the same "ERROR : 0" and no remaining volumes.
This is even worse. After 'lvm vgchange -a y' volumes which happen
to reside on the disk as a volume which was mounted on / are found.
But a volume located on another physical device is still not there
even after multiple runs of 'lvm vgchange -a y'.

anaconda log of failure with VG not being VolGroup00
I'm getting a similar problem when changing the default names of the volume
group and logical volumes.
Anaconda fails with an error message about failing to format the logical
Actually, this seems to fail even with the default names. I created the volume
group on a preformatted disk, I'm not sure if that has anything to do with that.
I believe this should be fixed now. We were deactivating LVM at certain points
which was causing the device nodes to disappear. That should be taken care of.
Please try a rawhide tree when they start showing up again and verify that this
is working for you. Thanks.
