Whoops. I tested the logic with the print statement commented out
directly above. I admit, I never actually ran the script completely,
allowing it to delete.

There is now a regular expression filter that it simply ignores those
files that don't match the expected pattern.
As for the ebuilds, I'm putting together an updated version tonight that
will optionally set up log rotation, and a cronjob to run this script.

Have you guys tried rescanning your channels? Sounds like the
broadcasts have changed since you scanned.

Is there any reason you cannot consolidate machines and save power while
not using virtual machines? There are several mechanisms that allow you
to isolate different userlands, while maintaining a single kernel, and
allowing full hardware access.

I have. It's not a trivial process though - I scan both capture
cards, delete a few duplicates by hand and then run a script to set
Callsign, Visibilty, xmltvid etc, so it's possible that, if I made a
mistake, then I made the same mistake on the rescan.
I'm still getting plenty of successful recordings on the channels
concerned though which would imply that the scanning is OK, wouldn't
it?
What I've done now is enabled '-v dvbcam, record --loglevel debug' in
the mythbackend log and I've noted the mplexid and sourceid fields
from my channel table so , if it happens again, I should get a bit
more information.

OK. I guess I see why the first time I posted the log files didn't
work. I
tried posting them again and got a message that my email was being held
because the message body was too big (>40K) There's no way the message
body
was greater than 40K, but the attached logfile was. I will try zipping
the
files and resending.

That

and
in the cases where it works properly it certainly doesn't store anything

OK -- it took a little doing but I finally got there. I deleted my
local
definition of the "Default" storage group on my slave backend so that it
would go back to using the one on the master, but every time I tried to
run
a test, it would record fine because it kept picking a local directory.
I
finally had to go back and temporarily delete from the master's Default
storage group any local directories so that all directories were remote.
Then when I ran the test, it failed as before.
I have attached the backend log and the output from the storagegroup
query.
A lot of the initial error messages in the log are due to the fact that
I
removed directories from the storage group so now it can't find some of
the
previously recorded shows, but the error demonstrating the problem is at
the
end of the file where it tried to record the movie "Marnie" but failed.

I recently started using a variation of the cleanup script on the wiki
and after a few days discovered that some recordings were from the wrong
channel. I was very confused because manual test recordings were fine
and some of my scheduled recordings were fine too. It wasn't a couple of
switched channels, I had some BBC HD recordings that contained a
different channel yet others were fine, the other channel was working
fine in it's own right too.
In the end I found that I made some mistakes in the script and I was
ending up with some channels sharing the same channel number. Record on
the named channel rules worked fine, record an any channel rules were
fine if the wanted channel was first in the channel list but recorded
the wrong channel if the wanted channel was second.
Maybe your problem is different but the symptoms sound similar and I
found it very confusing for a day or two.

Well, thank you very much to Ian and Warpme for your help.
The raid used to be fully synchronized and speed seemed to be OK. But as
you pointed out correctly, this is not a mythtv related problem.
I tried a little bit more and disconnected the HDDs which contain the
raid. So PC was only running with one HDD containing OS and
mythtv-recording-directories. I produced heavy load to this disk
(recording, watching live-tv on a different frontend, nfs-transfer of
recorded mpgs via GB-LAN, doing md5sums of recording-directories) and
noticed no errors any more.
This lead me to the decision to take a quite radical step and kill the
raid5-array. Instead of this I build a simple group of these disks via
LVM as one big virtual disk. It took me 2 days to copy the old archived
recordings from external USB2.0 back to the computer.
Any further tests lead to no errors anymore. So the problem seemed to be
the raid itself. I don't know if this is a kernel-issue, or probably
related to the fact, that one of the raid-disks has 4kb-block size,
while the other ones have 512byte blocks. The partitions seemed to be
aligned properly. I couldn't find any IRQ-conflicts either.
So for now this case is closed. I reconfigured my backup-scripts to do
backups more frequently. The raid5 would have been quite a 1st degree
insurance against diskfailure. Sadly this doesn't work for me. Happily
the new backend now works as expected (except for the raid).

I loaded Myth frontend on the client machines from the Applications
section
of Ubuntu which offered the frontend and backend separately. I chose
just
the frontend however it installed both - like it or not as if it was a
dependency. I can see the value in having a secondary backend however I
cannot understand why having a single Front -end installation should not
be
"recommended". What is the architectural reason for this is a pure
Backend
/ Frontend configuration? You should have the flexibility to choose
according to your needs. It appears it was a decision of the designers
that
was not fully considered which I found somewhat counter intuitive. It's
good that Mandriva gives you the additional flexibility.

Just a heads up that this isn't the best way to use disks for Myth
recordings.
Myth will quite happily use multiple directories - so you can let it
put recordings on 3 disks. Done this way, if you lose a disk, then
you only lose the recordings that are on that one disk.
If you make a large volume group with LVM, then you have no
redundancy and the loss of any single drive will mean the loss of
everything in the VG.

True, but I figure there are few things that are going to cause such
IO (or at least seeking) that will preventing the disk catching up
within a few minutes. I don't mind an occasional stutter during
playback, but having recordings corrupted to the point of
unwatchability is more than a tad annoying.

What are we talking about, in terms of large buffers, I mean. Even 6
concurrent HD-streams of probably <= 20Mb/s only generate 120Mb/s being
15MB/s, with todays drives easily being capable of > 80MB/s.

Well, as I mentioned earlier, the mythtv-recording-directories are not
located on the LVM, there's a dedicated disk now for those. The VG holds
old recordings which were converted to x.264, and are frequently saved
to external disks as backup. So if one drive of the VG fails, I simply
have to restore the backup.
