I'm reinstalling F11 proper after running the various preview releases and anaconda is not seeing any lvm partitions. This is occurring on two different systems. Basically I'm trying to do a clean install, reformatting /boot and / and keeping all the other partitions the same. I choose custom configuration for disk layout and I see the physical partitions including the lvm container partition, but no logical volumes. Dropping to a shell, I can run 'lvm vgchange -a y' and see that the VG vg0 is there and it contains my 5 LVs. Both these systems had their LVM layouts created many Fedora releases ago when LVM first was introduced.
I just tried this on another server that is brand new and has only had F11 preview installed on it (i.e., no old LVM layout here) and anaconda still doesn't display any LVM paritions.
On my laptop, I tried just recreating the LVM setup since it didn't see the old one and that blew up anaconda. I tried to report it but it the bug buddy like dialog said it was a dup and I'd get cc'd. At this point, I can't install F11 at all even though I'm currently running the preview + rawhide/official updates.
I was able to install on my laptop by doing a "remove linux" and then customizing it from there.
Were you using any kickstart? If so, you might be hitting this bug: https://bugzilla.redhat.com/show_bug.cgi?id=503681, which is F11 Common Bug: https://fedoraproject.org/wiki/Common_F11_bugs#503681
Yes, that appears to be my problem exactly. And I was only using a kickstart to have the updates install at the same time and that is now taken care of by anaconda with a simple checkbox. *** This bug has been marked as a duplicate of bug 503681 ***
