This is possible but perhaps tricky. You'll be using mdadm from the command line and the general steps would go like this:

1. define your current partitions as raid devices
2. define your RAID array as raid1 and tell it that your second drive has "failed" (not exactly true, but it won't remember in the morning)
3. start the rebuilding process, where mdadm will see your spare drive as a new replacement for its raid1 array and will begin copying your contents to the new drive.

In the end, you'll have all of your partitions replicated on each drive except for the boot partition. This means that if the physical drive that has your boot partition dies, you won't be able to boot your system, but you still won't have lost any data. Alternatively, you can copy your boot partition onto a second drive, but it doesn't provide a seamless boot failover: you would need to manually edit GRUB to direct its boot to the backup drive.

It's been a while since I've done it, otherwise I'd give you more detail. This is a decent resource:

Practice it once or twice in a virtual machine and you should have no problems. If you do decide to reinstall, you can get the k/ubuntu alternate CDs, which set it all up for you with a little fiddling in the partitioning section.


PS. I may be doing this myself in a couple of weeks so please post back any good finds.

Aye. For now, nvidia's cards seem to perform better ... or so I hear -- I just keep buying nvidia. Eventually, the recently-open-sourced ATI drivers will catch up and that will be the way to go.

I see. I understand s-video is both lower resolution & lower quality, so I'm not expecting 1080 - sorry my diagram is misleading. However, s-video seems to be the best option available for HTPC without going full-HDCP (windows) or using the haup Component-In DVR (which also requires windows).

Are there any cards that take component, dvi, or even hdmi in? I couldn't find any...

Hi all,
I'm about to build my first LMCE rig and the list below is what I've picked out. Suggestions and pointers are welcome :)

Intended Use:
Hybrid server
watch video in 1080i - the video card & TV can do this.
record TV shows - using SVideo for now
play DVDs
change channels on the STB/DVR - possibly a DirecTV HR21
three hard drives in RAID 5 and be able to add more later (using software MDADM)
run HDMI (video + audio) from LMCE to TV
run Svideo from STB to LMCE
install/configure other server apps from within Kubuntu, backup 3 PCs, share folders, more..
SSH or otherwise remote into the Hybrid for admin tasks
output stereo or 5.1 sound

 Hauppauge WinTV-PVR 150 MCE 274 PCI
 AMD Athlon X2 4450e 2.3GHz Socket AM2 45W
 2x  G.SKILL 1GB 240-Pin DDR2 SDRAM DDR2 1066
 3x  Western Digital Caviar SE16 WD5000AAKS 500GB
SIIG IC-710012 7.1 PCI
Antec Neo Power 430
 (random DVD drive)
 (custom case)

I expect I will also need a couple of dongles for the blasting & remotes. I'd like to get the fiire remote but it's way too much, so for now I'll probably get a cheap remote or gyro mouse. Eventually, I'd like to add the new Hauppauge DVR.

Two Questions:
Can LMCE record in h.264 (mpeg4)?
How good would the video look when watching live HD? (STB >> s-video >> LMCE >> hdmi >> 1080i Samsung TV)
