[Bug 1095064] [NEW] Automount of luks encrypted DVD fails

[Willem Brown]

Public bug reported:


I have created an encrypted UDF file system on a DVD. If I insert the DVD into the drive it prompts for the pass phrase but then it fails with the following message: 

"Error unlocking device: cryptsetup exited with exit code 1: device-
mapper: reload ioctl failed: Invalid argument"

I can manually mount the device if I specify the "-r" option.

* Open the DVD without the "-r" option:

$ sudo cryptsetup luksOpen /dev/sr0 d1
Enter passphrase for /dev/sr0: 
device-mapper: reload ioctl failed: Invalid argument

* Open the DVD with the "-r" option:

$ sudo cryptsetup -r luksOpen /dev/sr0 d1
Enter passphrase for /dev/sr0: 

$ sudo cryptsetup status d1
/dev/mapper/d1 is active.
