I've done this now and the procedure is fairly easy and very safe. I did a test run with VMs first, of course. You don't need to vgchange/vgexport etc. These changes do not carry over, anyway. A new system will find all volumes and make them active. But this doesn't matter. For a kickstart ins

Answering here to all three replies, and thanks for all of them! I think it should have been clear from my wording that I want to install from scratch and wipe the existing OS. I do not want to dualboot or "save" anything (or much) from the existing OS. I just want to reuse the existing LVM str

2011-01-09 Thread Kai Schaetzl
I want to replace an existing 32bit with a 64bit installation (Centos 5). There's an existing LVM with lots of partitions. Most are used for Xen guests. The system itself uses only one of them plus a separate /boot partition that is not on LVM. What's the best course of action here? Should I do
