The following setup seams to indicate that bioctl aint able to handle 2
+ TB volumes.


Controler: Perc RAID 5/i, mfi0
HDDs: 4x1TB
RAID: 5
Configuration: Configured during the controler BIOS
Volume 00 appears as: sd0

disklabel -E sd0
#                size           offset  fstype [fsize bsize  cpg]
  a:       5857345473               63    RAID
  c:       5857345536                0  unused
#

I had to use "b" + "*" to gain the whole space!
You might wanna document that in the manpage?

Before using "b"+"*" the size was limited to: 1562363692
But ok..: Created a partition called "a" and attaching it to softraid0 for
the Crypto discipline.
sd1 appears but aint able to use the whole space.
"b"+"*" did not solved it.

16 partitions:
#                size           offset  fstype [fsize bsize  cpg]
  c:       1562363692                0  unused
#
# dmesg |grep sd1
sd1 at scsibus2 targ 0 lun 0: <OPENBSD, SR CRYPTO, 003> SCSI2 0/direct
fixed sd1: 762872MB, 512 bytes/sec, 1562363692 sec total
# dmesg |grep sd0
sd0 at scsibus0 targ 0 lun 0: <DELL, PERC 5/i, 1.12> SCSI3 0/direct
fixed sd0: 2860032MB, 512 bytes/sec, 5857345536 sec total
# uname -a
OpenBSD kerberos 4.5 GENERIC#2052 amd64
#

Does anybody knows how to may solve this?

I can use sd0 completly and without issues.
It just seams softraid has somehow problems to get the whole space.
Another Bug in the great FS layer(-logic) of OpenBSD...

And if you dislike your console simply use bioctl -i mfi0 and it will
fuck up (no aborting possible! Very cool and l33t if you're connected
via Serial connections).
Of course bioctl is in D+ state making it impossible for root to kill it... ;-)

I just thought others might should be aware of this too.
But if anybody knows how to use a big disk with softraid pls enlight me.

Kind regards,
Rembrandt
