Hello, I have similar problem, recently discussed in netbsd-help.
I've read all the thread and had some experiments on working 6.0_BETA2/amd64 box. Initially task was: Make RAID1 set on 2 3TB disks. But I still have no luck: wd2: 2794 GB, 5814021 cyl, 16 head, 63 sec, 512 bytes/sect x 5860533168 sectors 1) dk2 device over raid device over dk0/dk1 doesn't work. I also beleive this setup won't autoconfig properly. [root@crux ~]$ dkctl raid7 addwedge storage3 128 5860532703 4.2BSD dk2 created successfully. [root@crux ~]$ newfs -b64k -O2 /dev/rdk2 newfs: /dev/rdk2 partition type is not `4.2BSD' 2) newfs over raid device over dk0/dk1 doesn't work either [root@crux ~]$ newfs -b64k -O2 /dev/rraid7d /dev/rraid7d: 764436.3MB (1565565568 sectors) block size 65536 3) raid device over /dev/wd* give me 2TB RAID [root@crux ~]$ gpt show raid7 start size index contents 0 1 PMBR 1 4294967167 So, as I understand we got problems using *ANY* device ending with 'd' greater 2^32, but not with disklabel itself. So the only working solution seems to be dk2 -> raid -> dk0/dk1 -> wd2/wd3 , but it dont work too.
