Hey friends,
my new external HDD has a sector size of 4096:

# disklabel -h sd8
# /dev/rsd8c:
type: SCSI
disk: SCSI disk
label: My Passport 0827
duid: 9210ccc858d72f52
flags:
bytes/sector: 4096
sectors/track: 63
tracks/cylinder: 255
sectors/cylinder: 16065
cylinders: 45599
total sectors: 732558336 # total bytes: 2.7T
boundstart: 64
boundend: 732558273
drivedata: 0


I wanted to create a crypto raid on that drive and used the following commands to create one.

fdisk -igy sd8


Then i created a partition with disklabel -E sd8 resulting in the following disklabel:

16 partitions:
#                size           offset  fstype [fsize bsize  cpg]
  a:             2.7T               64    RAID
  c:             2.7T                0  unused


Now i wannted to use bioctl -cC -lsd8a softraid0 but i get the following error message:

softraid0: sd8a has unsupported sector size (4096)
softraid0: invalid metadata format

I looked around and found an old email from Kenneth R Westerback on this mailinglist where he stated that the "4k problem" was solved at "c2k15" but never commited. Is there a reason it never got picked up again? Here i a link to the old post: http://misc.openbsd.narkive.com/xjppPBE5/softraid-4-bioctl-8-vs-non-512-byte-sectors-disks#post6


I am on OpenBSD 5.9 AMD64.

Thanks and greetings
Leo
