Good day,
Hope this helps,
Yup some final confusions :-(
The raid seems to be working fine. But how do I access the RAID partitions?
it seems I have 3 copies of the OpenBSD system on "wd0a" and "wd1a"
and also raid0a
and how do I run on the OpenBSD system that is on "raid0"
I 'l explain.
1) I can boot both from wd0a and wd01
2) I am running the RAID kernel

How do I access the wd0d partitions that are Raided?
Do I need to mount them manually under /
Just a bit confused :-)
Thank you so much
Kind Regards
