Besides, if an application actually needs to do this much to follow system quotas, doesn't this mean that apps that just don't care about quotas can do whatever they want?

Klaus ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr Applications, which do not care about quota, can not really do what they want, they only can not write to the filesystem if the quotalimit is reached. Thats what quota is made for. But if you would like to react on such a limit in a more intelligent way you have to ask for that limit and not only for the simple filesystem limit. statfs(..) only delivers the 'physical' limits of the filesystem. So vdr could not make new recordings when the limit is reached because it checks for the filesystemlimit. This value shows vdr to have enough space. So it never starts to delete old recordings. I have changed the patch a little bit because there was a logical fault in it. But now it's for vdr-1.6.0. I have not tested the xfs part because currently I use only ext3 or nfs. So this should be tested maybe by somebody else or if you would like to implement such a logic into vdr leave it out or comment it out or do it your own way. The problem here is that by each kind of check of the different filesystems you receive different numberunits of something what is called a block.

But the VDR Software doesn't recognize that. It does not start to mark
old recording for removing. In the menu overview it show still some
hours free space util the end of the complete filesystem.
Now my question: Do I have to configure something special in VDR that it
recognizes the Quota setting of that directory or have I to use
userquota for the user of VDR (in my case it is root but if it is the
only solution I could change it to a regular user, but only if it helps
for my problem)?
Some revision data:

Hi List,
because nobody answers me I have to answer myself:
No, VDR is not able to follow Quota. It is looking only for the standard
size parameters of the filesystem... ;-(
So I had to help myself. The outcome is a patch/hack for my current VDR
Version 1.4.5. But it should be easy to apopt it also to newer versions.
I have glued it together out of several GOOGLE sniplets. Maybe

little patch it was sufficient.
To use this you have to install the quota package on your server and
maybe the quota-utils on your client. For your convenience I have
included already the rquota-files into this patch. (I hope its according
to any licenses)
Have fun
