Man gzip and cpio in case I misremember.

In a work directory:

   gzip -dc <initrd name> | cpio -idmc

Down in the resulting directory, there is an init file.

Locate the ignorelockingfailure and change the VG name there.

Still in the top level working directory (<the created initrd dir/..>)

   find <initdirname> | cpio -oac | gzip --best ><new initrd name>

Move it to the boot dir, change grub.conf appropriately. More perilous,
but possible: make it the same name (pls save the original somewhere)
and no grub name change needed.
