This is a userspace bug not a kernel one. There is a workaround, which is to perform the pvmove one LV at a time using the --name option. (For each LV, run pvmove -n .) The patched code is in the upstream lvm2 repository: git://sources.redhat.com/git/lvm2 http://sourceware.org/cgi-bin/cvsweb.cgi/LVM2/doc/?cvsroot=lvm2 http://sourceware.org/lvm2/ It was only last night that the code incorporating these changes passed our public testsuite for the first time, so I think it is still premature to be using this on production systems. But this means I hope to be in a position to make the first development release containing a fix for the problems quite soon. (I added assertions to catch other instances of the related problems - it was more than just pvmove affected.)
