This LV was initially created as 512M in size. I extended it to 1G and experienced the same thing. I then created a new LV of size 2G, copied the contents of the first LV to the second, and used that as the domain's root filesystem. I no longer get this problem. I then deleted the original LV and renamed the new LV to the name of the original and things still work. I am able to do: dd if=3D/dev/sda1 of=3D/dev/null in the Xen domain and not receive any errors so I have to conclude that all blocks of this second LV are readable. So is this an issue of the layout of the LVM extents on disk? Will I get this problem again? Should I be pursuing this on the LVM list, here, or maybe even with the Xen folks?
