    As some of you know I run an Openfiler SAN at home (12 disks over two raid 5 controllers and the OS disk).
    Due to some failings on my P5Q WS Pro board (basically the system would crash for no apparant reason), I decided to change system boards on it, unfortunately the crashes had caused my boot device to not load properly and that meant that I couldn't use vsphere to transfer the vm's and templates\isos off the iscsi shares on Openfiler. What this meant to me was that I had to do a complete re-install of the OS (not an easy task when the P5E WS Pro board was installed and wouldn't boot from CD (it's sata which apparently can be a problem), nor could I boot it from a USB key and install it that way, instead I had to configure my Win 7 box to run an FTP server and load it up that way. Anyway I got it installed in the end.

    Now to the important part. Whilst installing OF was easy, it found my Volumes but it hadn't restored my shares.
    What I did find nifty however was using the restore function I managed to restore my shares using the previous backup (a tgz file all of 30kb in size), not only did it restore my shares it didn't break my new networking cards either.

    A quick update later I now have my fully functioning OF SAN back courtesy of my backing up the config file 2 months ago.

    So rule number 1 when playing with OF, backup the config and store it elsewhere, that way if you need to restore the config you can (rather than starting from scratch again which really would have been a pain).
