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. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
