Hi all,
I was not sure which list to send this to, so I choose a couple that
looked like decent fits, please advise if there is one more specific to
the encryption.
I am currently working on a project where we are converting some of our
filesystems to an encrypted fs using LVM2. We are running RHEL:
"2.6.9-55.0.2.ELsmp #1 SMP Tue Jun 12 17:59:08 EDT 2007 i686 i686 i386
GNU/Linux"
We setup an encrypted filesystem using one of the open partitions on the
physical hard drive using "cryptsetup create /dev/sda3" We have
verified this using the cryptsetup status, This shows the filesystem as
being encrypted as aes_plain 256 bit key. We then created an LVM and
mounted the filesystem using the LVM.
All seems to be well, except when our testers ran the following command:
head -c 5000 /dev/sda3
They got some output that includes clear text and obviously not
encrypted data (along with encrypted data). Some things are date
formatted strings like 20050912 which appears quite a few times in the
mounted filesystem, and in the raw device (/dev/sda3).
I can post the exact commands that were used to create the filesystem,
but they are basically
create partition ...sda3
cryptsetup create /dev/sda3 (prompts for passphrase)
pvcreate
vgcreate
lvcreate
mount
(TIA) any help (or light shed on this) is greatly appreciated!
