    I followed the steps and I got it to work on a running Debian LVM system for my system imager. Now, Should one of the drives fail. How can I tell? Also, Does this mean that theoretically I could stick a blank disk in place of a good disk and RAID will parse, format, and dump the data to the disk? Or am I just really making a huge assumption with that? Also, how often do they sync up to each other? Is that done automatically if I put new data, remove files from the system? Really really new and unfamiliar to RAID and these are probably some pretty basic questions but I want to know should one of my drives ever quit

    cat /proc/mdstat
    and you'll see if the array is ok.

    The recovery procedure is shown on

    Syncing happens immediately and automatically.

    You can specify an email address in your mdadm.conf so it tells you when something's wrong.
