Description Daniel Bahrdt 2009-10-14 14:53:10 UTC

If you repartition your device and forget to change the settings in conf.d/dmcrypt you might loose a lot of data. I have tried this on a 200GB ext4 partition. Fortunately fsck.ext4 could recover the data (I haven't activated the swap partition).
What I'm asking for is a check like fdisk -l /dev/sda | grep /dev/sda10 | grep swap as I can't think of another usage of random keys except with swap-partitions.

Comment 2 Daniel Bahrdt 2010-02-08 21:38:06 UTC

I just want to share some kind of workaround until this gets fixed:

swap=crypt-swap
source="$(fdisk -l /dev/sda | grep 'sda9' | grep -wq 'swap' && echo '/dev/sda9')"

fdisk only works on partitioned disks.  it fails on files, loop setups, ...
