How can I change the name of an unencrypted LUKS partition mounted as the root filesystem?

When I installed Linux, the block-device-path of my root LUKS device was /dev/md125 and the unencrypted partition was /dev/mapper/md125_crypt. I have since renamed the MD device to /dev/md0, and now I'd like to rename the LUKS partition to /dev/mapper/md0_crypt. Here's what I've done so far: 1. Replaced all references (in the various *tabs) of md125_crypt 2. Updated my initramfs 3. Updated grub2 However, when I reboot, my system doesn't make it to the point of asking for my decryption password; it says something about being "unable to find the root partition". I've also tried adding a symlink (/dev/mapper/md125_crypt -> ./md0_crypt) but it doesn't seem to persist after a reboot. **How can I rename my unencrypted LUKS partition such that I can successfully boot after doing so?**
