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.

diskd(1) General Commands Manual diskd(1)
Name
diskd - disk daemon; wait for disk to be inserted
Note
This manpage has been automatically generated from fdutils's texinfo documentation. However, this process is only approximative, and some
items, such as cross-references, footnotes and indices are lost in this translation process. Indeed, these items have no appropriate rep-
resentation in the manpage format. Moreover, only the items specific to each command have been translated, and the general information
about fdutils has been dropped in the manpage version. Thus I strongly advise you to use the original texinfo doc.
* To generate a printable copy from the texinfo doc, run the following commands:
./configure; make dvi; dvips fdutils.dvi
* To generate a HTML copy, run:
./configure; make html
A pre-made HTML can be found at: `http://www.tux.org/pub/knaff/fdutils'
* To generate an info copy (browsable using emacs' info mode), run:
./configure; make info
The texinfo doc looks most pretty when printed or as HTML. Indeed, in the info version certain examples are difficult to read due to the
quoting conventions used in info.
Description
The diskd command has the following syntax:
diskd [-d drive] [-i interval] [-e command]
Diskd waits for a disk to be inserted into a given drive, and then either executes the command or exits. This program can be used to auto-
matically mount a disk as soon as it is inserted.
Warning
This program works by switching the motor on for a very short interval, and then seeking to track -1. This might damage hardware in the
long run. Amigas, which also use these techniques, are known for having problems with their disk drives no longer spinning up properly
after a few month of usage.
Options
-d drive
Selects the drive to observe for disk insertion. By default, drive 0 (/dev/fd0) is observed.
-i interval
Selects the polling interval. The interval is given in tenths of seconds. Default is 10 (one second).
-e command
Gives the command to be executed when a disk is inserted. If no command is given the program simply exits. Typically, the command
mounts the disk. It can be a shell scripts which probes for several filesystems and disk geometries until it succeeds.
Bugs
* Automatic unmounting cannot yet be handled. It is indeed not enough to scan for disk removal, because when the disk is removed, it
is already too late: There might be some buffers needing flushing. However, the fdmountd program allows automatic unmounting by
using the SYNC mount options, which switches off write buffering (see section fdmount).
* The drive motor is running all the time, and on some computers, the drive led flickers at each time the drive is polled.
