"pvdisplay" will print information about unusable space in the "PV Size" line. As long as that's larger than the LUKS header (2MiB, I believe) you should be able to do a live migration to an encrypted PV using a second disk. > > Interesting. And one can do it on purpose: - big segments (64MiB) - partitions with a little overhead (100.01GiB, so there are 10MiB of extra room) - PV, mdadm or luks headers will never be a problem -- Roberto Ragusa mail at robertoragusa.it -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
