My server Dell R210 runs a Debian squeeze with hardware RAID1 (H200) preconfigured. But I notice that there is mdadm running. Sometimes in backup, or in OS upgrade (to Debian 6.0.4), I have messages like this:
W: mdadm: /etc/mdadm/mdadm.conf defines no arrays.
W: mdadm: no arrays defined in configuration file.
Are they safe to ignore? How do I disable mdadm? Just a /etc/init.d/mdadm stop, a bit of observation then apt-get remove mdadm?

The message you have about mdadm.conf don't garanties you don't have arrays. The configuration file rarely contains any array.
If you see no array, you can remove the mdadm package. Or leave it, no problem.
