Any pointer on what does this > mean ? From "man mdadm" (if you know where to look) Follow or Monitor Monitor one or more md devices and act on any state changes. This is only meaningful for raid1, 4, 5, 6 or multipath arrays as only these have interesting state. raid0 or linear never have missing, spare, or failed drives, so there is nothing to monitor. You are presumably trying to monitor a raid0 (which isn't meaningful) and mdadm is telling you (in its own idiosyncratic way) that it isn't going to monitor it.
