Yes that's right. I was simply using the commands explained at this url :-) >>> 1) put the DRBD resources into secondary mode (on each server) no simply drbdadm down resource on both >>> 2) stop the DRBD service on each server no >>> 3) resize the disk partition used for the DRBD devices on each >server (the disk partition used as meta-disk is not modified) NO first dump the metadata drbdadm dump-md resource > /tmp/metadata then you can grow the device - then reimport metadata and then drbd up. Then Filesystem resize.
