Re: Setting up ccd RAID 1 Howto OpenBSD 4.1
If I remember correctly, you have to use FS type RAID, and not FS type FS_RAID. for the partition layout, the /boot on 100MB is to allow the machine to boot, but after that, you put all your files in logical subdivisions of the raid array. I my case, I didn't use wd*a (/boot) in the /etc/fstab, as I don't need it for day-to-day operation. Last thing, instead of writing the raid.conf file under /etc, copy it (if you can) from man raidctl, raidctl is very very very bad at interpreting this file, and fail with a useless error message whenever it finds whitespaces, tab, or CR where he didn't intend to... nico On 9/13/07, Jake Conk [EMAIL PROTECTED] wrote: Hey, I tried following that article but I got stuck at the part where you start partition your second drive.

(Side note: on e.g the platform sparc64 you use 4.2BSD, not RAID) Then go on and follow the article again. There are other articles like that out there, I followed some other that was clearer on that point... Nowdays I tend to improvise. I prefer to retain the whole base installation that was used to build the raid-aware kernel (if I have the diskpace) in case of disaster. Then one does not have to start with a broken mirror - it can be created whole at once. By the way, I recall rumours about some other RAID implementation coming in OpenBSD 4.2. Does anyone know, just rumours?

Basically I don't know how to get this ball rolling I'm very new to OBSD and BSDs in general, coming from Debian Linux (which now does raid1 from the installer). I notice that both OBSD and NetBSD use raidframe and ccd. The NetBSD FAQ has a chapter on setting up raidframe for root raid1. Perhaps it would give some direction. I do not know if it is the correct approach for OBSD. Doug.
