[SOLVED] Oops! Crypto fail

[mark9117]

I am messing around with disc encryption and created a small encrypted partition on my laptop. I didn't like the way it worked (just created a partitoin accessible only by root), so I dleeted the partition. Now, I can't get into diskdrake:

Code: Select all

# diskdrake
device-mapper: table ioctl on crypt_sda12 failed: No such device or address

Trying to open up Manage Disk Partitions in the MCC, it just exits abnormally.

I can see an sda12 partiton in fdisk:

Code: Select all

fdisk -l

But I'm not sure what to do about this. Anybody out there have any suggestions?

Thanks.

Edit: Never mind. I removed the sda12 partition with parted. It looked a little like this:

Code: Select all

# parted
GNU Parted 3.1
Using /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) rm 12                                                           
(parted) quit
Information: You may need to update /etc/fstab.


Pretty cool.

Quick addendum - you also have to clear out the /etc/crypttab file. Otherwise, it tries to mount the encrypted volume that no longer exists.

I'm just saying.

Thank you for the head up.
IMHO diskdrake should fail more gracefully. Post bug?
