I discovered this issue with Kubuntu 14.04 which I installed from scratch using a CD/DVD. During installation I selected full-disk encryption as well as an encrypted home directory -- my understanding is that home directory encryption also encrypts the swap space.
Below is the current state of the drives. Note that: 1. 'blkid' does not list swap, and /proc/swaps is empty; however, 2. /etc/crypttab has entries that apparentlly correspond to the encrypted disk as well as the swap, as does /etc/fstab; but 3. 'swapon' does not like the swap drive/s. I only have a single physical disk (plus the optical drive). ======blkid=============== $ sudo blkid /dev/sda1: UUID="f8ac0867-47e7-4c5c-8988-ab680388df78" TYPE="ext2" /dev/sda5: UUID="2fb151ab-a2e3-4007-9cff-a61034e7a0c7" TYPE="crypto_LUKS" /dev/mapper/sda5_crypt: UUID="8tXqxi-M5bU-r75F-4VPY-ur6s-60P6-3qK3uV" TYPE="LVM2_member" /dev/mapper/kubuntu--vg-root: UUID="67d318ec-2121-4da9-a705-7258033d64b3" TYPE="ext4" =========fdisk=========== $ sudo fdisk -l Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00037417 Device Boot Start End Blocks Id System /dev/sda1 * 2048 499711 248832 83 Linux /dev/sda2 501758 625141759 312320001 5 Extended /dev/sda5 501760 625141759 312320000 83 Linux Disk /dev/mapper/sda5_crypt: 319.8 GB, 319813582848 bytes 255 heads, 63 sectors/track, 38881 cylinders, total 624635904 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/mapper/sda5_crypt doesn't contain a valid partition table Disk /dev/mapper/kubuntu--vg-root: 313.4 GB, 313377423360 bytes 255 heads, 63 sectors/track, 38099 cylinders, total 612065280 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/mapper/kubuntu--vg-root doesn't contain a valid partition table Disk /dev/mapper/kubuntu--vg-swap_1: 6417 MB, 6417285120 bytes 255 heads, 63 sectors/track, 780 cylinders, total 12533760 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/mapper/kubuntu--vg-swap_1 doesn't contain a valid partition table =========/etc/fstab========== # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed.
