However, the root partion is not often written to so presumably I could
have / on the USB stick and swap, /var, /usr, /tmp et al. on a mirrored

Resilient RAID

2010-05-20 Thread John Rowe 
I need an inexpensive OpenBSD system that will survive a disk failure,
to act as a firewall.

My understanding from the on-line documentation and the list archives is
that the new RAID system, softraid, does not support having the root
partition on RAID meaning that if the system disk fails the machine
crashes. 

Is this (still) correct?


If so, the installation notes for 4.7 suggest against using RAIDframe
(and even mis-spell the hyperlink!), which raises two further questions:

What is the most recent OpenBSD release that does support and document
installing on to RAID?

Should I install that version or am I best off trying to adapt its
installation instructions for 4.7?

Thanks

John
