Netbsd, what is dk?

Question

Simple question, today making iostat on netbsd machine I see..

    iostat 2 3
          tty              ld0               ld1               dk0               dk1               dk2               dk3               dk4               cd0             CPU
     tin  tout  KB/t  t/s  MB/s   KB/t  t/s  MB/s   KB/t  t/s  MB/s   KB/t  t/s  MB/s   KB/t  t/s  MB/s   KB/t  t/s  MB/s   KB/t  t/s  MB/s   KB/t  t/s  MB/s  us ni sy in id

---explanation---

ld0 is the first virtio hd
ld1 is the second virtio hd
cd0 is the first SATA cdrom

what is dk1-4?

nope, is refer to gpt partitions, disk are ld0 ld1 or sd0 sd1, or wd0 wd1.. — elbarna, Feb 12 '24 at 16:45
BSD treats GPT partitions as Disks. This is only only a semantics difference. MBR/DOS style disks are limited to 4 Partitions. See this post — eyoung100, Feb 12 '24 at 17:05

Solution found..gpt. I usually use "disklabel" to create bsd slice, but this create MBR partition. To create gpt partition on disk (really simple..1G on virtio disk)

gpt destroy ld1||echo "Not gpt!"
gpt create ld1
gpt add -a 2m -l TRY -t ffs -s 1G ld1

Iostat confirm operation ok (a new dk appear, dk5)

      tty              ld0               ld1               dk0               dk1               dk2               dk3               dk4               cd0               dk5             CPU
 tin  tout  KB/t  t/s  MB/s   KB/t  t/s  MB/s   KB/t  t/s  MB/s   KB/t  t/s  MB/s   KB/t  t/s  MB/s   KB/t  t/s  MB/s   KB/t  t/s  MB/s   KB/t  t/s  MB/s   KB/t  t/s  MB/s  us ni sy in id

You really should try bsdlablel - Manpage, if you're going to use GPT partitioned disks — eyoung100, Feb 12 '24 at 17:15
