Probably obvious to many, but if you find yourself in this situation
using the Red Hat / Fedora default layout created by Anaconda, the
easiest solution is normally to "steal" one extent from the auto-
configured swap LV, and donate it to the mirror conversion:
# swapoff -a
# lvresize -l -1 rhel/swap
# mkswap /dev/rhel/swap
# swapon -a
# lvchange -m1 ...
This will always work with the automatic layouts provided by those
distros.
Regards,
Bryn.
