This is a lab/test machine.  I have a couple of others that have a
similar LVM layout, and all of them have hot-swap drives.  I likely
moved a drive around at the wrong time.

It is already active, and I just tried a reboot.  sda3 is still

I have 3 LVs on sdb1, they are working fine.

I have a copy of my Linux Distro CDs and spare space for sdb1 snapshots
on sda3.  They are not working.

Obviously I can recreated the CD copies, but I prefer not to do this.

Is there something else I can try?

FYI: None of this data is very important, so I won't complain too loud
if you ask me to do something and it ends up blowing everything away.
