Thread: "NO SWAP SPACE AVAILABLE" on Encrypted LVM

hi there fellow (k)(x)(l) ubuntees,

today manually installed ubuntu 11.10 (32bit) on encrypted lvm.
have reserved 4096mb of swap, same amount ram.
ubuntu unable mount/detect/see/use swap.

setup follows:
80gb harddrive
1000gb hardrive

80gb harddrive partitiond follows:
unencrypted boot partition: 512mb ext2 mounted /boot
encrypted lvm (1) = volume group 1 79gb split in 3 logical partitions.
vg1-lvroot 25gb ext4 mounted /
vg1-lvswap 4,1gb swap space
vg1-lvhome 51gb ext4 mounted /home

encrypyred lvm (1) = volume group 2 1000gb spilt in 2 logical partitions.
disk_c 500gb ext4 mounted /backup_c
disk_d 500gb ext4 mounted /backup_d

blkid gives me following output:

and /etc/fstab holds following static file system information.
# <file system> <mount point> <type> <options> <dump> <pass>

/dev/mapper/vg1-lvhome /home ext4 defaults 0 2
/dev/mapper/vg1-lvswap none swap sw 0 0
/dev/mapper/cryptswap1 none swap sw 0 0

swapon doesn't work either:
ignus@ubuntu:~$ sudo swapon -a
swapon: /dev/mapper/vg1-lvswap: read swap header failed: invalid argument
swapon: /dev/mapper/cryptswap1: stat failed: no such file or directory

did somewhere make fatal error during partioning setup , need on again or can resolved on installed system? have tried gparted doesn't see logical volumes on encrypted lvm no luck there. thank time , advice in advance.

cheers,

ignus

could use "code" tag?
way terminal output read this:

code:

random data awesome terminal

then i'll see if can figure out.

though, on encrypted systems, not create swap partition, swap file on encrypted volume.

got guide somewhere @ home... i'll link when home.
