[ubuntu] mdadm RAID 5 issue

http://ubuntuforums.org – Hello, I have just upgraded my server to Ubuntu 12.04.1 LTS and created a 4 disk RAID 5 array using mdadm (separate from the system disk). Everything works well - except for one issue. The status of the raid changes continuously from 'clean' to 'active' every 5 seconds or so, and the drive status LED blinks accordingly. Each individual drive shows 'active - sync'. Any suggestions? (Hardware)
