Description of problem: I want to install RHEL5 B2 over FC6 on my laptop, preserving /home but wiping /. Both partitions are under LVM. When I tried setting this up manually, anaconda complained about not having enough space in the VG; in fact, it said the VG had -32MB free space, which is the size of one extent. See the attached screenshot. I don't know of any other way to install without wiping /home, other than trying to tell anaconda not to format /, which may or may not work around this problem.

Same for me. I got arround the issue by resizing swap, which was also in LVM
Pretty ugly. pn-ack
Is this still happening? If so, can you show me how to reproduce it?
Aha, you've got to start with a much older set of LVs.
Should (hopefully) be fixed in the next anaconda build. Upgrades from RHEL4 and new installs need to both be tested, and "lvm pvs" needs to be run after each to make sure there's no unrequested free space left on any physical volumes.
A package has been built which should help the problem described in this bug report. This report is therefore being closed with a resolution of CURRENTRELEASE. You may reopen this bug report if the solution does not work for you.
