Re: [Nfs-ganesha-devel] owner and group issue.
Thanks! we will add support_ex functionality in our fsal as part of that will see if the issue in question goes away.

Re: [Nfs-ganesha-devel] owner and group issue.
If you are not using open2, then file creation could easily be wonky. Also note that the non-support_ex functionality is being deprecated so your FSAL would need to be converted to support_ex if you wish to migrate to newer Ganesha (and there will be lots of reasons to migrate to V2.6 and later as we move forward).

Re: [Nfs-ganesha-devel] owner and group issue.
Daniel, We are using open call not open2 call. But i verified our FSAL is returning correct owner and group id for getattr call right after file gets created. And it is intermittent issue and can be reproduced easily. This is happening basically during process starts. Thanks, Sagar.

Re: [Nfs-ganesha-devel] owner and group issue.
This is not a known issue, as far as I'm aware. I'm assuming you never changed 4.txt at all, it just fixed itself on it's own? This means, to me, that the correct value is being set on the file, but an incorrect one is returned to the user. That's a getattr() issue, and it resolves itself because after 60 seconds, the attribute cache expires, and so the next getattr refreshes the cache, fixing the issue. Is your FSAL correctly returning the attributes in attrs_out in it's open2() call?
