Upgrading an encrypted system


Hi,

I'm looking to upgrade from Lenny to Squeeze and would like to check if there's anything special I need to do. Software-wise there's nothing out of the ordinary on the system but, while looking into upgrading, I've read some horror stories regarding encrypted systems. I've only previously installed from fresh.

Here is how my current partitions/filesystems are set out:

. sda1/sdb1 > raid > ext2: boot
. sda2/sdb2 > raid > luks > lvm > ext3: root
. sda2/sdb2 > raid > luks > lvm > ext3: swap
. sda2/sdb2 > raid > luks > lvm > xfs: data
. sdc1/sdd1 > raid > luks > lvm > freespace: vms

Would this just be a standard upgrade, as per these?

I will be backing up important data before I attempt to upgrade.

Thanks in advance,

cryptsetup does 2 kinds of FS. one is the raw cryto volume and the other is LUKS. In most cases upgrading luks volumes never had any issues although I saw some issues with the raw crypto volumes (due to change in the default algo).

Thanks for the reply - seems like I should be OK (at least as far as the luks goes!). I will give it a go this week.

EDIT: The upgrade completed with no problems whatsoever. Very easy to do. Libvirt etc improvements well worth the upgrade.
