Oops, that's not completely true: pvresize currently is not smart enough to move allocated data out of the area to be freed, according to its man page. But you have other options, e.g., you can attach another disk, create a PV on it, move the data there, rearrange the first disk as desired, and move the data back, all while the system is running. That's what's so fun about LVM. -- Matt -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
