Good day. I am glad I have the chance to play with NetBSD again. Yesterday I
put pxeboot_ia32.bin inside pxelinux.cfg/default, so I could PXE while I PXE:-)
Seriously, it went fine, and the the vendor-class-identifier trick helped the
dhcp server differentiate normal BOOTP requests from those initiated by pxeboot
-- this is only optional, one can also provide 'netbsd.gz' at the root of the
tftp share to avoid interacting with the boot prompt. I was just in the mood
to talk.
Today's topic is rather iSCSI. I am pleased to read in the NetBSD 7.1
TARGETS(5) manual that,
It is possible to use the word ``size'' to use the full size of the pre-
existing regular file given in the extent name.
However I then realized that it goes for _file_ extends only, not bsd
partitions. In fact, when setting up an extend as a partition,
# extent file or device start length
extent0 /dev/rwd0e 0 size
# target flags storage netmask
target0 rw extent0 0.0.0.0/0
I get this error when trying to start iscsi target daemon (identified size is
**zero**),
Starting iscsi_target.
Reading configuration from `/etc/iscsi/targets'
target0:rw:0.0.0.0/0
extent0:/dev/rwd0e:0:0
DISK: 1 logical unit (0 blocks, 512 bytes/block), type iscsi fs
DISK: LUN 0: pid
423:/usr/src/external/bsd/iscsi/lib/../dist/src/lib/disk.c:720: ***ERROR***

pid 423:/usr/src/external/bsd/iscsi/lib/../dist/src/lib/disk.c:886:
***ERROR*** error allocating space for "target0"
pid 423:/usr/src/external/bsd/iscsi/lib/../dist/src/lib/target.c:1990:
***ERROR*** device_init() failed
iscsi_target_start() failed
So I guess all I could wish for is the 'size' feature to be able to handle
devices sizes automatically.
Best regards and thank you for the good code
