[linux-lvm] pvmove problems

[michael <cs networkingnewsletter org uk>]

I'm trying to reduce a logical vol so that I can remove a HD from it.  
However, I get errors with pvmove but I don't know why. I saw some old
postings with a kernel patch but the URL is extinct.

I'm running Fedora: Linux xxx.phy.umist.ac.uk 2.6.22.1-41.fc7 #1 SMP Fri
