FYI, unless you have a freshly installed SL6.1 machine, it is likely that you will not receive email from mdadm when your array fails. This is because mdadm is not runing. It looks like it always crashes on startup unless all md arrays have metadata version 1.0 or later - there is a version number listed in /proc/mdstat - if there is an array without version number, mdstat will crash. This was found and fixed in Fedora.
For more details, see https://bugzilla.redhat.com/show_bug.cgi?id=787276 P.S. Aparently this problem is fixed in RHEL/SL6.2: cd /triumfcs/mirror/SL/6.2/x86_64/os/Packages rpm -vh --upgrade mdadm-3.2.2-9.el6.x86_64.rpm service mdmonitor restart no mdadm crash got many emails from mdadm mdadm still running. -- Konstantin Olchanski Data Acquisition Systems: The Bytes Must Flow!
