Bug#306495: pvmove: should autoload dm-mirror kernel module

[Mark Sheppard]

Package: lvm2
Version: 2.01.04-3
Severity: normal

When trying to use pvmove I got the following error:

  mirror: Required device-mapper target(s) not detected in your kernel

It took me quite a while to work out that the solution was to run
"modprobe dm-mirror".  It would be far move helpful if pvmove itself
could load the dm-mirror kernel module when it needs it.

Or at the very least it should tell you to try running "modprobe
dm-mirror" in the error message it produces.

Cheers,
Mark.
