I guess it is not SCSI, I guess it is not IDE, right ? DRBD needs in its meta-data operations atomic updates of rather small units of data on disk. Therefore DRBD's meta-data layout is somewhat optimized for IO Subsystems with a sector-size (=small possible block size) of 512 byte. -Philipp -- : Dipl-Ing Philipp Reisner Tel +43-1-8178292-50 : : LINBIT Information Technologies GmbH Fax +43-1-8178292-82 : : Schönbrunnerstr 244, 1120 Vienna, Austria http://www.linbit.com :
