lvmkd is the logical volume manager kernel daemon and I would not try to kill it, but I doubt that a kill would succeed. If your disks were mirrored, why did you use dd? The logical volume should have been intact by using the other side of the mirror. When you replaced the disk, lvm had to sync it if it was mirrored and this syncing operation is proabably was is causing your load. One other thing to try is to check for OS patches to LVM. But this does sound like a resync. I think it's lvdisplay that will show you the status of a resync.

WARNINGS
Due to a hardware limitation in many floppy drives, the act of checking for media causes mechanical action in the floppy drive. Continu-
ous polling of the floppy drive will cause the drive to wear out. It is recommended that polling the drive only be performed during periods
of high use.
