I find that very surprising.

Too late now but you don't need GPT for this if it's OpenBSD-only,
just do 'b' '*' in disklabel.

Did you also use the -b option?

The FAQ now lists the steps for EFI setups:

Did you see this already?



I saw that but i dismissed it since i do not need a EFI boot for my
"data container" disks. (aside of the container disks i've got a system
disk with traditional image & rsync backups).

Anyway i did not find "anywhere" the mention that a softraid 1 needs to
be based on a bootable units. As well as "huge" discs management topic
seemed to me not so covered. Such idea of mandatory boot partition
looked weird to me... i just posted an open question on the list.

Sorry for the noise.

softraid & GPT configuration.

[Eric Huiban]

Hello,

I should have miss something in the man pages with softraid and bioctl. 
But i want to form a RAID 1 between two 3TB harddisk (2.7TiB) and it is 
acting like 2TiB MBR disks with OpenBSD 6.0.


fdisk -ig sd1 is OK. same for sd2. No EFI boot partition.

disklabel is ok with a 2.7TiB ".a and .c" RAID partitions on each 
disk. (the check with newfs and mount is also OK). checked as per man pages.


but when i construct the RAID with

bioctl -c 1 -l /dev/sd1a,/dev/sd2a softraid

the softraid reports only  2TiB partitions on sd1 and sd2 thus building 
2TiB raid unit sd3.


Does someone have any advise about such behavior, or about what i'm 
missing ? Both man, apropos and google seem a little bit shy about such 
topic.


Regards,
Eric.
