Hi, I'm trying to do linear mapping for part of a disk that used also as boot device, but the dmsetup create fails as this disk is used. is there any way to workaround that? the partition that I'm using as rootfs and the part that will be used as linear device don't overlap, does that mean there will be no risk for data corruption if I modified the dm code to disable the exclusive access? saeed -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
