I'm running R4V5 and I have been manually deleting some of my recordings (via mythweb and an xbox frontend) and I noticed that my % free disk space has not been increasing. I first noticed it through myth-web which is reporting: "5 programs, using 12 GB (3 hrs 30 mins) out of 30 GB". Wow... considering I'm using mpeg4 I knew something must be wrong.

So I logged in and checked it out:



Same result. Bare in mind that I have no mp3s, roms, etc on my /myth partition, only recorded shows. Just to be sure, I did an inode check:


No problems there. So I decided to try another method of seeing how much space was used:


Ah! That's more like it. There are 3.3GB of files on that partition. So where has my other 9GB gone? I tried restarting the backend to see what effect that would have:


Now my free space is back! Has anyone else experienced an issue like this or know why it might be happening? It doesn't seem like I would need to restart the backend in order for space to be freed up. Thanks.

It sounds like there is a file descriptor leak in the backend. The files aren't getting closed for some reason, so despite the directory entries being unlinked, the inodes (which actually control the space) can't be released.

I'm not sure what the problem is that you're having, but I have noticed that if you delete recordings via MythWeb, you have to refresh the page in the browser for the free space info at the bottom to update.

It's not a simple matter of refreshing the web page. The space is not available by any means until the backend is restarted.

The file descriptor leak sounds like the problem. Is this something that should be brought to the attention of the developers? Is there any way I can troubleshoot it further?

If there is a file descriptor leak it seems like everyone would have noticed this problem and it would have been fixed long ago. What's unique about my situation that is causing this to happen? I never delete files directly from the backend, I always do it either through my xbox frontend or the mythweb interface. Is this unusual?

There has been chatter about this on the myth list, but mostly regarding 0.16. They're saying it only affects people with remote frontends who do not use nfs to access myth content. It's fixed in cvs I guess.

This is happening to me with the frontend and backend on the same machine. Obviously remote nfs is not the only case of it happening.
