I have two discs in a RAID 1 configuration.
I'd like to break the mirror and have two separate discs - then run an rsync job nightly to back one up to the other (as has been discussed here previously).
What's the best way to break the RAID 1 configuration and make the DNS treat the two discs separately?
I'm happy using mdadm if that helps.
TIA

I found this http://dns323.kood.org/forum/viewtopic.php?id=5287.
BUT I was hoping not to have to reformat either disc.

There is AFAIK no easy way to undo a raid, without reformatting the disks, but it's possible to split it in two single disk raid1 arrays. You need to have shell access.
Remove one disk, bootup the box. It should show degraded. Now enter the command
/sbin/mdadm --grow -n1 --force /dev/md0
Reboot, and the box isn't degraded anymore.
Repeat for the other disk.
I don't know how the firmware will treat this. Possible it will only assemble and mount one disk. Then you'll have to assemble and mount the other manually.
