mdadm: metadata format 00.90 unknown, ignored.
 
I created a RAID 5 array on my Ubuntu 8.10 box using this guide: http://bfish.xaedalus.net/?p=188

When I run "mdadm --monitor --scan" I get:
Code:

mdadm: metadata format 00.90 unknown, ignored.
I checked my mdadm.conf file and it looks like this:
Code:

# mdadm.conf
#
# Please refer to mdadm.conf(5) for information about this file.
#

# by default, scan all partitions (/proc/partitions) for MD superblocks.
# alternatively, specify devices to scan, using wildcards if desired.
DEVICE partitions
ARRAY /dev/md0 level=raid5 num-devices=3 metadata=00.90 UUID=13f95aef:9c364189:75b10d3a:87a53e2f

# auto-create devices with Debian standard permissions
CREATE owner=root group=disk mode=0660 auto=yes

# automatically tag new arrays as belonging to the local system
HOMEHOST <system>

# instruct the monitoring daemon where to send mail alerts
MAILADDR my-personal-email@gmail.com

# definitions of existing MD arrays

# This file was auto-generated on Sat, 06 Dec 2008 00:02:16 -0500
# by mkconf $Id$

If I remove "metadata=00.90" from the "DEVICE partitions" section this notice goes away, but I don't want to remove it if it is supposed to be there...

Any advice on what I should do?

p.s. Here are the results of "sudo mdadm --detail /dev/md0"
Code:
