Hi Neil, The following changes are available at: git://github.com/djbw/mdadm.git The stand out change in the diffstat is the incorporation of the Option-ROM logic for handling arrays with different 'family numbers'. The scheme the Option-ROM uses to resolve conflicts is not completely amenable to mdadm's container scheme. The end result is a corner case that requires user intervention. The user will need to assign new container membership ids to prodigal disks that are returned to their system of origin. More details in the commit log and code comments. Also notable are the changes to cleanup mdmon instance management. I kept the status quo in deciding against implementing an "abstract namespace socket" for the control path. Initramfs environments can take two paths: 1/ Use the built-in 'newroot' option to hand off monitoring to an mdmon binary launched from the target file system. Currently Dracut will not be able to use this method as its 'switch_root' command does not allow an mdmon instance to be launched between $NEWROOT/dev and $NEWROOT/sys being available and the initramfs exiting. 2/ Keep the mdmon instance from the initramfs running until it can be killed by the final-root initscripts. The socket will not be available so this should be done while the file system is still read only and any writes from journal recovery have quiesced. In testing this I noticed that wait_for() (util.c) occasionally timed out on Fedora 11, but not Fedora 9. Increasing the loop count to 50 got around the issue, but need to investigate what is holding up our requested symlink.
