After many weeks of playing around I finally have my Myth box working with my Dishnetwork box and with the IR Blaster. I have also worked out all of the bugs that were haunting me.

For the above reasons I ask all of you experts this ...

Can I add a second hard to my current setup ? What I mean is this ..

I currently have a 40 gig drive in the box. I have also purchased a 120 gig drive, now I don't want to go through all the pain I had to with starting from scratch I'd just like to add the second hard drive to the system and move the /mythtv partition over to the 120 gig'r. Is this possible ? And if so how ?

Yep, you can do that.

Basically, you'll just install the drive, partition (fdisk) and format it (with mkext2fs/makefs.ext2 or equivalent depending on whether you want ext2, ext3, xfs, etc.). Something like:
Quote:
fdisk /dev/hdb
<make your new huge partition>
mkfs.ext2 /dev/hdb1


You may also be interested in copying your current /mythtv/* onto the new drive. Just do this after the format and before the reboot. You'll have to mount the new drive temporarily (probably somewhere in /mnt). Something like this (of course, adjust the /dev/hdXX to your actual devices if different):
Quote:
mkdir /mnt/newdisk
mount -t ext2 /dev/hdb1 /mnt/newdisk
cp -p /mythtv/* /mnt/newdisk
umount /mnt/newdisk
rm -fr /mnt/newdisk


Then, edit your /etc/fstab and change the /mythtv partition from /dev/hdaX to /dev/hdbX (or whatever your real /dev/hd's are set to).

Then, when the system boots, it will automatically mount the new disk as /mythtv and everything should be rockin' :D

Awesome. Thanks. What would the best file system be ? I'm guessing ext3.

I believe that ext3 is the default for KnoppMyth auto-install. I have heard many people praise XFS also.

I'd probably just go with ext3 unless you want to do a bit of digging and look into XFS.

I would stick with ext3 since I think the devs have mentioned possibly taking xfs support out in future releases.

I love ReiserFS ! Why ?
because it is fast, and it is silent !
really I made the experience that reiser makes less noise the ext2/3. please dont ask me why :-)

I used lvm for my second drive, I edited the /etc/fstab file and now I'm afraid to reboot :?

The lvm how-to page describes how to create a script (/etc/init.d/lvm) and then perform update-rc.d lvm start 26 S . stop 82 1 . for a Debian installation. But the script /etc/init.d/lvm was allready there. So I guess I'm wondering if the script is allready started at boot time and if i should perform that update-rc.d command?

No, LVM isn't started at boot. The only daemon that start are daemons needed for MythTV to run and Apache.

Do you recommend using the lvm script that was allready there, or creating it they way the specify in the lvm how-to?

Would the update-rc.d command cause the lvm script to start at boot?

As I have not used LVM, I cannot recommend anything. Yes, doing update-rc.d will cause LVM to start on boot. update-rc.d lvm defaults

Posting an LVM howto in the Usage/Howto section would be nice...

Yes, a LVM howto would be great. If you've got the time frustrated please do so.

No problem, just got back from class. I write one up tomorrow after work :) I was going to post everything I needed to do in R4V2 to get pvr 350 tv-out, and all the other bells and whistles to work.

After searching the forum for second hard drive information I came upon this thread. I see that one can turn the new hard drive into the myth partition, but is it possible to keep the original myth partition and have the secondary drive as a second myth partition?
