+. Remove the device from the array.
+. Shut down the machine.

+. Add the new partitions to existing arrays. Wait for the arrays to rebuild.
+. Mount the array and change the UUID of the swap partition in /etc/fstab
+. Rebuilding the boot system
+.1. Boot with Centos7 rescue image in troubleshooting mode
+  * FIXME: provide such image or info how to boot
+.2. chroot to system, identify new disk, run grub2-install /dev/newdisk
