Re: Preparing for zfs filesystem

["Robert G. (Doc) Savage" <dsavage@peaknet.net>]

Trying to remove all traces of the old software RAID capability so
there's no conflict with the ZFS creation. So far I have:

1. Unmounted the array from its mountpoint:
        # umount /pub
2. Removed the array's entry from /etc/fstab:
        /dev/md127p1   /pub   ext4   defaults   1 1
3. Disable creation of the array at next boottime:
        # mv /etc/mdadm.conf /etc/mdadm.conf.backup

I've obviously missed something because upon reboot, dmesg says:

Can someone please suggest what's doing the drive detection and logical
metadrive assembly?
