Can't really help you there. I have a Buffalo Linktheater networked DVDPlayer, 
which isn't small.

Not sure about pkgsrc. The greater community of networked DVD players seem to 
use "wizd". I wrote my own for the hell of it, called "llink". The companies 
have their own too, PCcast, etc, they are usually java and Windows only.

Now these are media streamers which have UPnP discovery in them, but they are 
probably not 100% UPnP? I don't mind adding code if there are bits missing to be 
fully compliant.

Net necessary exactly what you want, but there's probably some mileage in 
looking at an embedded device running vlc. Get a micro ATX board and run 
NetBSD from flash. Get multimedia/vlc and run it with vlc -f udp://. It'll 
then just sit there waiting for data to be sent to it. For further 
excitement it has a telnet interface which you can use for remote control.

multimedia/vlc again. You can stream pretty much anything at such a 
client using vlc. You can also transcode to alter bandwidth, scale, 
etc. For example (all on one line):
vlc -vvv dvdsimple:///dev/cd0a <at> 2:2 --loop --sout
"#transcode{vcodec=mp4v,scale=0.75,vb=768}:standard{access=udp,mux-ts,url=192.168.1.15}"

[Raidframe] How to recover a degraded mirror without a spare?

After two years of solid service, a drive in my Raidframe mirror has
failed, and I'm having trouble finding information on how to recover.
The man pages talk about recovery in terms of reconstruction onto a
spare, but I don't have a spare in my dinky little 1U box.

Instead, I need to replace the failed drive, then recover the mirror.

The naive sequence of operations would be:

  1. Shutdown
  2. Replace failed drive with new blank drive
  3. Boot

But I'm not sure what I'd to to tell Raidframe that the new wd0d isn't
the wd0d that was there before.

Another worry I had about this procedure is that Raidframe might
become confused on reboot because it find a majority of its database
replicas.

So then I came up with this sequence:

  1. Remove the failed wd0d from the configuration with raidctl -c.
     (I think this would leave an intact mirror, but one with a 
     missing component?)
  2. Shutdown
  3. Replace failed drive
  4. Boot
  5. Introduce the new wd0d as a spare, and reconstruct onto it.

Re: [Raidframe] How to recover a degraded mirror without a spare?

You can simply replace the failed drive (there is no need to remove it first).
Put a disklabel on the new drive (not needed in your case if using wd0d)

Then:
raidctl -a /dev/wd0d raid0
raidctl -F component1 raid0
 (or component0? use raidctl -s raid0 to find out)

When you say `replace' I am not sure whether you mean, `physically
replace', or `raidctl -F'.

The system can only accommodate two physical disks.  So I have to
remove the dead disk first, and I'd rather the system were powered off
when I did that. :-)

So I guess another way to put my question is: if I power off,
physically replace the failed disk, and restart, how will Raidframe
react to this?

I *think* what you are saying is that, whereas now I have:

  wd0d: failed
  wd1d: optimal

after restarting the machine I will have:

  component1: failed
  wd1d: optimal

and, therefore, I will be able to introduce (the new) wd0d into the
RAID without any complications.

Have I understood you correctly?

Re: [Raidframe] How to recover a degraded mirror without a spare?

Yes you have understood correctly.

Most of the RAID systems I have setup are mirror on 2 IDE disks.
In the few cases a disk has failed, I:
- turn the machine off (in many cases the system has frozen anyway)
- remove the old disk and put a new one in
- boot
kernel messages show which disk is being used and the missing one should become component0/1
