Somewhere on the cryptsetup page there was a hint how to reencrypt a partition withhout reformatting. Basically you use dd to read from the plain device and write to the same device through the encryption layer. Something like this: # cryptsetup create encrypted /dev/sdx1 # dd if=/dev/sdx1 of=/dev/mapper/encrypted bs=10M I would not try it without a full backup and all fingers crossed... -- bye Adalbert -- fedora-list mailing list [email protected] To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
