[OpenAFS] (stackable file system) aufs stalls on some operations over OpenAFS

[Erik Braun]

Hi,

I discussed this topic almost 3 months ago on the aufs mailing list, but 
had at this time other things to do. Now I can look at this problem again, 
since it is still present in Debian Testing with OpenAFS 1.6.9 and the 
shipped Linux kernel 3.14.7.

In short, the computer stalls on some file operations when stacking an 
aufs directory above an OpenAFS directory, no matter, if the OpenAFS is 
writable or not.

The author of aufs sees the problem (specifically from his point of 
view as not an expert for OpenAFS) in lock operations in OpenAFS and 
suggested to ask the OpenAFS maintainers.

For more information, please see the entire thread here:

Please tell me, when you need more information.

with best regards.
Erik
