Those two guys went WAY above & beyond the call of duty, even working with me until midnight last night when I know I would have rather been with my family. But, they stuck with me through the thick of it, answering EVERY SINGLE QUESTION I had (at least once!), and walked me through the entire process. They made it EASY!!! Thank you, guys!

This surprised me as I'd had good luck with them before. But, SATLUG came through in & with flying colors. I am amazed.

Heh, I enjoyed it. I have a raid5 set up on my desktop because I was
lucky enough to have someone give me 2 free 500 gb drives, plus I
already had a 500gb drive in my desktop. I always want to make sure
that I have my knowledge up to date just in case I were ever to have a
major problem. This was kind of like a game of chess with 2 weeks of
Yea there is no telling what will happen to a file that has a few bits
missing in it. If it is an executable file, it would be bad. But just
image and video files I am not sure one would even notice. Maybe a small
blip in a video or a discolored area in an image? Worse case would be
not being able to open the file...
I mentioned rsnapshot for backups and attached my conf file in one of
these emails (not sure which one). That is what I use.
As far as getting your email for mdadm working right that is a whole
First off, see if you have a file called "mbox" in /root. On unix
systems many programs communicate by sending emails to root. You can
email any user by default as long as they are all local (on the same
machine). And to my knowledge all these emails go into a file called
"mbox" in the user's directory. The default program in ubuntu that
handles all these emails is exim4 I think. It is the MTA, mail transfer
agent (or smtp server).
If you do have the mbox file in /root open it and search for "mdadm" and
you will probably find where it first emailed you about the raid failure
many months ago ;)
From there I would start another thread called "Forwarding root email"
or something like that and hopefully some more people will know about
this. I run my own email server so I don't really have to worry about
many things. You are just wanting to forward your email to an outside
server. That might involve going to http://www.dyndns.com/ and making
your own domain name (for free) and/or finding out if your isp offers
you their own email servers to relay off of. Most public email servers
(hotmail, gmail,yahoo,etc) will block emails from dynamic ip ranges.
There are ways around it though.
It is a pretty big topic. This is one way:

think there are simpler ways. I wouldn't worry about it yet. Lets see
what the list has to say. I will be out of town the weekend.
