[NFS-Ganesha-Devel] fsal_close is not called after writting a file

Hi Matt and other experts, I used ganesha 2.7.6. I tried to write a file using RGW FSAL. however fsal_close() is not called. As you said before, RGW close will trigger real writing. So RGW files are not saved in backend. Could you help me to let me know what's wrong? I see nfs4_op_close() didn't call fsal_close(). Is it as expected? Thanks, Marvin
