Hi,
I am trying to migrate from Linux 2.4.23 to Linus
2.6.0-test11. However, my /usr and /home filesystems
are both LVM1 Logical Volumes and so it's vitally
important that I be able to mount them under
2.6.0-test11.
My userspace environment contains both the LVM 1.0.6
tools and the LVM2.2.00.08 tools, and my init scripts
decide which set to use based on whether or not devfs
contains the /dev/mapper/control device.
Obviously, everything is fine on 2.4. However, 2.6
only finds and activates the volume group containing
/home. (This is actually an improvement over the
LVM2.2.00.08 tools, which failed to find either volume
groups!) The tools (vgscan, vgchange -ay) complain
about finding a "duplicate" PV on /dev/hda2, and say
that they will ignore it. Natually, I have *not*
mounted either filesystem under 2.6 yet!
Anyway, this is what 2.4.23 says about my Volume
Groups:

My original intention here was to be able to "grow"
both these filesystems by adding another disc later.
As it turned out, the disk was plenty big enough...
;-).
Anyway, am I doing something obviously wrong here? Or
is there a bug in the LVM2 tools?
Thanks for any assistance,
Cheers,
Chris
