<snip> Just on a side note: I'm currently working on a patch to make disk geometry information available through sysfs (for all those devices that provide getgeo) and and extended patch to make it writable through the same interface by introducing a setgeo function as a companion to getgeo. Perhaps this'll make some of this easier... -- dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
