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 the reinstall with kickstart or better manually and reuse the existing filesystem? As I understand once LVM gets loaded it should find the volumes by itself, but will it be able to use the same naming scheme for instance? Or do I have to do some additional stuff, anyway?
Thanks,
Kai
Kai,
Make sure you backup your config files and whatever else is important for you (especially /etc/xen and/or /etc/libvirt if the machine is mainly dom0) and reinstall from scratch. Install from CD/DVD and be _very_ careful with the partitions. If you get it right, all volumes should be preserved. I did this a couple of times without problems (and will do it again once Centos 6 is released :> ).
