[Bug 484429] Re: Plugging in a LUKS device causes the following error: Error unlocking device: cryptsetup exited with exit code 239: Command failed: Device already exists
** Description changed:
Binary package hint: cryptsetup
+
+ When creating an encrypted drive in Palimsest (Disk Utility), the
+ application does not lock the disk when finished creating the encrypted
+ partition. Failing to lock the drive manually without ejecting will give
+ the appearance that the disk is no longer usable giving this error.
+ Bringing the key to another computer works because the luks mapper point
+ is not unlocked and already present on that system.
Steps to reproduce:
1) Go into palimsest (disk utility) and create an encrypted partition on an external disk.
2) Quit Palimsest
3) Pull the USB stick
4) Intert the USB stick
Result:
GNOME displays a dialog for the password. Once submitted, the following error comes up:
Error unlocking device: cryptsetup exited with exit code 239: Command failed: Device already exists
This is due to the mapping being Opened when the disk is created, but
never closed, which creates a conflict.
Workaround:
Do the following to resolve the conflict of the existing device i /dev/mapper.
$ ls -al /dev/mapper
(Identify the mount point for your drive, "sudo blkid" may help)
$ sudo cryptsetup luksClose devkit-disks-luks-uuid-<uuid>-uid1000
What is expected:
Palimsest (Disk Utility) is expected to "cryptsetup luksClose" the mapped device when finished creating the encrypted partition.
