I recently had a lot of trouble trying to use pvmove from the LVM suite, because I was using gentoo-sources-2.6.22-r2. After a lot of searching I found that the dm-mirror module is broken in this release and had to roll back to 2.6.21. Apparently this patch fixes the issue. I think it should be included in gensources http://www.kernel.org/pub/linux/kernel/people/agk/patches/2.6/editing/dm-raid1-fix-status.patch Reproducible: Always Steps to Reproduce: 1. Load up a gentoo-sources-2.6.22-r2 kernel 2. Try to use pvmove to move extents to a different physical volume, while the volume is in use. 3. Watch it fail. Actual Results: " Failure parsing mirror status fraction: 1 core Failure parsing mirror status fraction: 1 core ABORTING: Mirror percentage check failed." Expected Results: Extends move to new location.
The link is dead; please attach the patch.
