    Below, you will see the output from a metastat command that shows submirror
    d31 needing maintenance. I run a 'metasync d3' command and the system shows
    submirror d31 resyncing. However, after completion, it returns to the
    "Needs maintenance" state. I am a little baffled as to why and wondered if
    I could implore the gurus for some wisdom. Once d31 is in sync, I can
    metareplace the Last Erred disk in submirror d32. Do I need to place the
    system in single user mode to restrict access to the mount point this mirror
    is attached to? Thanks in advance for any help.
