Hello all;
I’m running into an interesting problem, and since I haven’t seen anything similar on the
mailing or issues list I thought I would see if there’s something I’m missing. Here’s my
setup:
1. CentOS 7 server running GlusterFS 4.1.4 and NFS-Ganesha 2.6.3
2. Windows 10 Pro system with nfs-client installed. Mounting the external NFS drive on
the system (v3), and have made uid and guid changes in the registry to match the uid for
the share.
With this setup, I’m able to copy most files from the windows system to the share without
a problem. However, if the file on windows has the ‘Read-Only’ attribute set, the copy
fails with a permission denied error, and looking at the Wireshark trace I’m seeing an
NFS3ERR_ACCES error. Is there something I can set in the NFS-Ganesha config file to
resolve this issue?
Thanks,
Steve

Can you post the wireshark traces? They would be helpful.

Hmm, is it possible that the windows NFS client is creating the file,
setting attributes to read-only on the destination file an then doing the
writes which fail? Maybe, try NFSv4 and see if it works better!

I don't think there's a v4 client for Windows.

Yea, no NFSv4 client for Windows. Could you share the wireshark trace? I'd like to
understand the flow. It may be that Windows doesn't make the right RPC calls to
accomplish copying a read-only file. Is the user making the copy the owner?

It’s definitely on the V3 CREATE call that throws the error. I’ve seen that there are V4
clients for Windows, but haven’t tried any of them yet – is there one you believe would
work?
Thanks,
Steve

Sounds like the same problem we recently had with ceph:
https://github.com/nfs-ganesha/nfs-ganesha/issues/349
If you see the NFSERR3_ACCESS happening on the COMMIT call, then gluster
may need a similar solution.

Jeff,
Thanks for the response. I did see that thread previously, with the only difference being
that the file isn't getting written out. Let me give that fix a try and see what
happens.
