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.

amtape
AMTAPE(8) System Administration Commands AMTAPE(8)
NAME
amtape - Control Amanda changers
SYNOPSIS
amtape [-o configoption...] config subcommand [subcommand_options...]
DESCRIPTION
Amtape is the command-line interface to Amanda's tape changers (amanda-changers(7)) and to the taperscan algorithm (amanda-taperscan(7)).
Tape changers maintain a notion of the current slot for each configuration. This may or may not correspond to an actual physical state of
the device, but is used by some taperscan algorithms to minimize searching through the slots.
Amtape uses the default changer. To use a different changer, use the config override option, e.g., -otpchanger=otherchanger.
SUBCOMMANDS
label label
Search for and load the Amanda tape with label [label], also setting the current slot.
slot slot
Load the volume in the given slot, also setting the current slot. The slot names current, next, first, and last have special meaning.
current
Shorthand for slot current.
inventory
Show the contents of all slots, based on the changer's cached metadata. This is a quick operation as it does not load or unload any
volumes, but is not supported by all changers.
show [slots]
Show the contents of all slots (or listed slots) by loading each slot and reading its label. This can be very slow. The slots arguments
is of the form 1,3-5,7.
reset
Reset the changer to a known state. This subcommand is intended to clear any unknown and potentially incorrect state the changer may
have stored.
eject [drive]
Eject the tape currently in the drive. This only applies to some changers. Specify a drive (by drive number) if more than one drive is
available.
clean [drive]
If a cleaning tape is defined for the changer, used it to clean the specified drive. The [drive] is optional if the changer only has
one drive.
taper
Run the taperscan algorithm (see amanda-taperscan(7)), displaying information about the progress of the scan.
update [what]
Update changer state. Consult amanda-changers(7) for changer-specific details on the format of what.
-o configoption
See the "CONFIGURATION OVERRIDE" section in amanda(8).
