Re: lvm 0.8 to 0.9 conversion?
I've been on vacation Nope, no snapshots. Well, I couldn't get my orginal volume group visible under both lvm 0.8 and 0.9. I don't know why. So I grabbed a big empty hard disk, created a new volume group that was visible under both, dded all the logical volumes over to it, updated fstab and removed the offending vg. I've yet to recreate the original vg, copy stuff back and remove the new drive. I should point out that the offending vg was relatively ancient, I think I created it when 0.7 was king under some something like 2.2.14.

Re: lvm 0.8 to 0.9 conversion?
Andre, One of my two volume groups, unfortunately the one with /usr, /var, /opt, and /home, isn't recognized by 0.9's vgscan when I reboot under 2.4.0-test13-pre4.But since the second volume group is visible, and you just told meit should be, then I can just copy volumes over under test13-pre3 and destroy and recreate the first volume group.
