The issue arises from using UUID to identify encrypted swap space: that is not supported, as stated at section 2.3 of the cryptsetup FAQ (https://code.google.com/p/cryptsetup/wiki/FrequentlyAskedQuestions#2._Setup):
"Specifying it directly by UUID does not work, unfortunately, as the UUID is part of the swap signature and that is not visible from the outside due to the encryption and in addition changes on each reboot with this setup." Just use disk IDs in /etc/crypttab and reboot, $ more /etc/crypttab cryptoswap /dev/sdaX /dev/urandom swap,cipher=aes-cbc-essiv:sha256 Bear in ming though the disk ID may change if you multiple disk in the system! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1153661 Title: The disk drive for /dev/mapper/cryptswap1 is not ready yet or not present To manage notifications about this bug go to: https://bugs.launchpad.net/cryptsetup/+bug/1153661/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
