Hi,

is the device still luksOpen?

If yes, you could try to grab the master encryption key from the running 
system. I think

# dmsetup table --showkeys DEVICENAME

should do the trick. You still won't be able to use LUKS to open that 
device, but at least you can use dmsetup directly to decrypt and access 
your device.


Good luck!
