Dear All, I have a machine with two Maxtor 160GB hard disks. I've installed OpenBSD 4.2 on first one and I would like to use second one as a mirror.
As far as I understood I will have to repartition and reinstall whole system to enable second disk as a mirror. All I want is to have software RAID 1. How to enable RAID 1 and sync first disk with second one without installing everthing from scratch like in those howtos? http://www.monkey.org/openbsd/archive/misc/0203/msg00803.html http://www.argon18.com/raid_openbsd.html wd0 at pciide1 channel 0 drive 0: <MAXTOR STM3160215AS> wd0: 16-sector PIO, LBA48, 152627MB, 312581808 sectors wd0(pciide1:0:0): using PIO mode 4, Ultra-DMA mode 5 wd1 at pciide1 channel 1 drive 0: <MAXTOR STM3160215AS> wd1: 16-sector PIO, LBA48, 152627MB, 312581808 sectors wd1(pciide1:1:0): using PIO mode 4, Ultra-DMA mode 5 I've recompiled the kernel with RAID enabled.
