I've got a related question as well, but it's not really LVM-related.
The thing is that there's something strange with either the IDE chipset
(a Promise card) or the corresponding driver that this disk is connected
to, which causes a kernel panic every time a read from a bad sector is
attempted. I figure I can "fix" that by connecting the drives to a
different computer while pvmoving, but I wouldn't prefer to do that, as
it causes downtime. Does someone on the list know of this problem and
how to work around it? I figure that I can attempt to fix the driver
bug, but I wouldn't prefer to experiment with that system...
