Dear Wollman, >From: Garrett Wollman <wollman@lcs.mit.edu> >For backwards compatibility, the FreeBSD 4.x kernel would fake up the >partition tables so that they would look like old (pre-slicing) >FreeBSD partition tables; i.e., the starting offset of the slice would >be subtracted from all of the partition offsets on read and added back >in on write. The disk partitioning subsystem in 5.x doesn't do this. >-GAWollman Thank you! I also want to know if I want use LVM(Logical Volume Management), I need create pseudo-device in "/dev". How can I do? In 4.x, I can use 'disklabel' to change partition's size, offset and type, but in Current, I coudn't do that. i.e. # disklabel -e /dev/da1s1 disklabel: ioctl DIOCGDINFO: Inappropriate ioctl for device but the 'da1s1' device-name exists in '/dev'. For my old experience in DP1, I compile kernel with option 'NO_DEVFS', so I can create pseudo-device as in 4.x. Whether I must use DP2 without DEVFS to use LVM?
