Neil, The kernel I'm using is... [root@kermit plainsite]# uname -a Linux kermit.thinkcomputer.com 2.6.32-71.el6.i686 #1 SMP Fri Nov 12 04:17:17 GMT 2010 i686 i686 i386 GNU/Linux However, I have downloaded an update that I can install and hopefully that will fix the issue. One other question: why do df, /proc/mdstat, and other utilities always list the RAID arrays in random order? I'm always expecting md0 to show up first, followed by md1, md2, etc. but this is rarely actually the way that the arrays are ordered. It makes it kind of confusing when different utilities do things differently.
