Hello Mag, sorry for my late reply. I think there is a misunderstanding. The bug I'm talking about is if you export Lustre by knfsd. It is not important if you do use any other NFS services on your MDS/OSS system. But if you should export Lustre by NFS using the kernel export nfs daemon, try to disable that.
