This weekend I have been spending most of my time rebuilding my KnoppMyth box by installing the lastest version, applying the patch to handle the new tv lisings provider, Schedule Direct, and adding a new 500GB drive for recording tv. I wrote down most of the steps to get things setup and plan to do a blog posting about soon. At the moment what I did want to post is a link to a page on how to add a second drive to linux. They are clear instructions and worked nicely. I'm mounting this new hardrive to the /myth/tv directory so that all tv recording will go to it.
If you're trying to do exactly what I did, then you also need to set the proper permissions back on the /myth/tv directory or you will get a bunch of errors. First set the owner of the directory back to mythtv by doing this
chown mythtv /myth/tv
Then to get the permissions exactly back to where the were I added write permission back on for the group by doing:
chmod g+w /myth/tv
You can compare the before and after permissions and ownership my doing ls -l /myth before you make any of these changes and then again afterwards.
