[linux-lvm] FYI: Going back to LVM1 from LVM2

[Rickard Olsson <richie webhackande se>]

For various reasons (when I fix it, I'll Tell the Tale) I installed LVM2 
today. It didn't solve my immediate problems, so I tried to go back to 
LVM1. However, the dev/vg_name/lv_name node had disappeared and even 
though both vgchange -ay, vgscan, lvscan and pvscan all reported seeing 
the lv fine, mount could not find it.

A reboot did not help. Panic lurked.

However, vgchange -an followed by vgchange -ay helped.
