Mirroring a hard drive?

[Deleted member 2077]

I would like to mirror a disk. Both are same type/size/model of disk. I would like to include all the boot information so it's also bootable. Any ideas?

Use GMirror:

# kldload geom_mirror
# gmirror label  rootfs ad0
# gmirror insert rootfs ad1

# gmirror status
         Name    Status  Components
mirror/rootfs  COMPLETE  ad0
                         ad1

then You may create bsdlabel ...

# bsdlabel -B -w /dev/mirror/rootfs

Why not just use dd?

dd(1)

dd(1) instead of RAID ... good one

I need to come up with a better acronym than GCFIWWDB

I thought the point of RAID was fault-tolerance through redundancy, not guaranteed corruption and filesystem inconsistency while wasting device bandwidth.
