Well I've had my mythbox set up and running in the living room for a couple of weeks now.

Just this weekend it didn't record some shows I was expecting it to. I've figured out that it is because /myth is %100 full.

I have autoexpire turned on. Isn't that supposed to delete old things when it needs space?

I feel like this is probably one of those stupid questions, but I really did search all the forums, gossamer-threads, and the mythtv docs and didn't find anything related. Everything I've read seems to indicate that it should be deleting some old stuff to make room for new recordings.

Any advice?

Just a guess, but you have a ton of roms or pictures or music files don't you?

How much is a ton?

Ok, I have ~300m of roms. That doesn't sound like a ton to me.

How does having lots of other stuff on the partition prevent myth from deleting it's old recordings?

Is it something funky, like, if I have lots of other stuff on the partition I need to increase the threshold for auto-expire?

well roms are tiny, so 300m is a ton. the problem is that the /myth partition is formated for large files, and runs out of inodes long before it is full if you put lots and lots of small files on it. It's been discussed several times before. do some searches on inode to see all the possible solutions.

How do you tell if the partition is out of inodes? does it say its out of space? or does it say it has space, but you cant add any files?

will give you the inode usage.
while

will give you human readable space usage.
now in this case the inode would show 99-100% while space would not.

I just ran df with no options. It showed %100 for /myth. Does that include inodes?

After your first response, I deleted my roms since I don't ever play them now that the box is in the living room. I was just trying out XMame & the other emulators.

I'll let you know if this fixes it.

I have no roms, no other videos, etc in the /myth directory only recorded programs using a PVR250 and I had this same problem. The drive reached 100% under df and didn't remove any recordings. Also no errors or warnings were given in the gui. Still a quick use of the delete programmes menu sorted it all, but really surely this is a mythtv issue not a knoppmyth one.

pete

did you have your recordings set to autoexpire?

Deleting my ROMS didn't fix my problem either. When I deleted my ROMs I also manually deleted a few old shows. By last night, the disk had filled up again and it's refusing to record new shows.


Pete - are you saying that once you deleted a bunch of shows manually that it started to automatically delete shows again, or do you still have to go delete shows manually every so often?

I agree that this seems like a mythtv problem, but it's much easier to ask questions here than on mythtv-users.

it may well be a myth problem, I know that myth has the settings to autoexpire and such, but I've never actually filled up my disk, so I've never run into it.

This is totally embarassing Total operator error.

I just re-checked my settings for about the 5th time... Autoexpire was set to on, but the Autoexpire threshold was set to 0 GB.

When I checked for this before, I was looking at new recording threshold which was not zero. I set the auto expire threshold to 4 GB. I'm sure that will fix it (my longest recorded movie is 3. something GB).

Thanks for your time XSecrets

While its embarasing it is exactly the same problem for me, so it least it has helped other fools

I think the defaults are

auto expire free disk space threshold (in Gigabytes): 0
Auto expire Frequency (in minutes): 60
Auto expire method: oldest show first
Auto expire: on
new recording free disk space threshold (in MB) 1200

As I suspect I just glanced at this page while setting up, say Auto expire: on and carried on.

Don't feel bad, it took me WEEKS to find that option. The only reason I never asked is that I don't want it auto-expiring things for me. (Though I was rather confused as to why it wasn't doing it...)
