Extended attributes question
 

Hi,
I was wondering if anybody confirm that you cant have other namespaces in linux' extended attributes than:

* security
* user
* system
* trusted

I was strac-ing glusterfs and found that it tries to read extended attributes like "glusterfs.content". My linux servers return -ENOTSUPP, and I dont know if its a glusterfs bug, or that I am missing something (i.e. a patch, a mount option).

Thanks in advance

I guess it depends on what extended attributes you mean, if you are talking about extended attributes stored in an inode, those are just key:value pairs that can be anything up to a max length. The filesystem needs to support them in order to use them, but I'm guessing most (other the fuse ones) do.
