I want to make my questions below more concrete. Let us suppose, I boot from wd0 and want to make a Raid 1 with wd1 and wd2, and that I follow the instructions in "man softraid":
# printf "a\n\n\n\nRAID\nw\nq\n\n" | disklabel -E wd1 # printf "a\n\n\n\nRAID\nw\nq\n\n" | disklabel -E wd2 # bioctl -c 1 -l /dev/wd1a,/dev/wd2a softraid0 # dd if=/dev/zero of=/dev/rsd0c bs=1m count=1 # ... disklabel in sd0 , new ffs there, ... What did happen? Where did bioctl wrote data? Where is written the new label in sd0? I will not be able to mount wd1 or wd2 as a single disc with ffs, but perhaps modifying the label? And where are the planned checksums written? I ask this because I want to know if I will make me dependent of todays stand of OpenBSD. Mounting ffs partitions of OpenBSD in FreeBSD and the opposite is possible without big problems. Will this change with Raid? Thanks Rodrigo. On Wed, 8 Mar 2017, Roderick wrote:
Few questions: (1) Where are the checksums written? (2) Where are the metadata of Raid 1 / Raid 1 with Checksum written? (3) Can I take a disc from the Raid array and mount it somewhere else as a normal ufs single disk? (4) Well, sooner than Hammer2, but when? :)
