From: Jakub Radtke <jakub.radtke@xxxxxxxxx> Currently, the sysfs interface allows bitmap setup only when volume is in an inactive state. For external metadata to add bitmap to existing volume instead of GROW, the UPDATE operation can be done. The patch adds a "bitmap" argument to the allowed values for UPDATE.
