There isn't such a feature as yet. With the next iteration of thin I'd like to get away from the fixed allocation block sizes that we're using which should greatly reduce the number of mappings that we need to create to provision a thick volume and so speed it up a lot. Presumably you want a thick volume but inside a thin pool so that you can used snapshots? If so have you considered the 'external snapshot' feature? > - can I obtain something similar by simply touching (maybe with a 512B only > write) once each thin chunk?
