Hello. Was wondering if there is any additional documentation for the mdadm program besides the man page. The values I get running mdadm -D are not immediately intuitive to me, For instance, why do I get "-1" under the "Failed Devices:" field ? or why is the "Total Devices:" field "1" while all others "2"? Thanks in advance for any pointers you can provide.
