Re: yet another "lost my partition" message



Hi Arno,
Thank you for replying
As it was not the root partition the one I was using with encryption I can boot without problems on my old system without mounting /home ( the partition with issue).
So, booted again in my old distro and ran the comand:
Âcryptsetup luksOpen /dev/sda10 home
It worked with my passphrase and I could see the /dev/mapper/home device created.
Trying to mount it I get:
mount /dev/mapper/home /mnt/
mount: you must specify the filesystem type

It seems to have lost the partition table so.
I am running testdisk now and trying to understand if this is really my partition without some blocks
I will be back with updates
Thanks again!

Hi Hugo,

first, there is a lot of info inthe FAQ here:
http://code.google.com/p/cryptsetup/wiki/FrequentlyAskedQuestions

Best boot a resuce system and try to decrypt the partition
manually with cryptsetup. If that works with any of the
possible passphrases, then all your data is still there.
If not, best post the error message here.

Manual decryption should work with a command like this:

> cryptsetup luksOpen /dev/<your device> e1

Afterwards the decrypted device is Â/dev/mapper/e1
You can mount that normally.

You can get header details like this:

> cryptsetup luksDump /dev/<your partition>

Ubuntu should have a resuce mode or life-cd mode that
allows you to do this.

Gruesse,
Arno
