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.

2.6.22 has a bug in dm-mirror status reporting, and as lvm relies on that to parse the progress of pvmove, it causes pvmove to fail, use 2.6.21 or patch your kernel.
