    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

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


    The recovery procedure is shown on http://www.howtoforge.com/set-up-raid1-on-a-running-lvm-system-debian-etch-p4


    Syncing happens immediately and automatically.

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