I was probably using verison 3.3-2 when I ran --re-add and the problem started. That is the latest version available for the verison of Ubuntu Server I am running. I then upgraded to v4.0 and later to v4.1-65 by building from source. Lesson learned. Question about mdadm documentation: Should the man page be updated to reflect the support for using sectors as units in addition to K M G and T? Glenn
