Maybe I do miss a point, but if I try to copy files in a directory
with not enough quota, copy action just stops silently and no error is
And worse: explorer does show the file is copied with full size...

E.g. I have a directory with 5 MB quota. A OpenAFS 1.7.8 client on
windows 7 32bit with a 100MB OpenAFS cache.

If I try to copy the 100 MB file into that 5 MB Quota directory via
drag&drop in explorer, the copy window opens and shows progress with
6-10 MB/sec up to 90% (size of cache, more or less). Now it hangs some
time. After some kind of timeout the copy windows vanishes and the
target explorer window does show the 100MB file with the expected size
of 100 MB as complete copied into target.
No error was shown.

If I check with another client, OpenAFS did only copy untill quota is
full, the 100MB file is cut down to 5 MB.

I do not think thats the expected behavior, or?

At least it looks dangerous, as users think the file is copied for
100% and delete the source and do see after some time, files are not
copied 100% into OpenAFS....

While if quota is already full, the start of a new copy into directory
with full quota is not started, shows a correct error.
