I haven’t actually done much with the pNFS portion of Ganesha, however I can try and point you in the right direction… You will need to implement the following FSAL methods for sure: layoutget layoutreturn layoutcommit getdeviceinfo fs_ds_addr_size fsal_pnfs_ds (assuming Ganesha will be your ds) fsal_pnfs_ds_ops (assuming Ganesha will be your ds) getdevicelist fs_layouttypes fs_layout_blocksize (if you support block layouts) the various fsal_pnfs_fs_ops (assuming Ganesha will be your ds) the various fsal_dsh_ops (assuming Ganesha will be your ds) Frank From: steve landiss [ mailto:[email protected] ] Sent: Friday, April 1, 2016 5:52 PM To: Frank Filz <[email protected]> ; [email protected] ; [email protected] Subject: Re: [Nfs-ganesha-devel] Unable to export any path with the VFS FSAL Makes sense. Frank, I have a basic FSAL backend working, but what would be the easiest way to have my FSAL implementation enable PNFS? That is, I want the client to ask me which machine my file lives on. Looking at the gluster code for a few hours now and it's not entirely obvious to me as to how to enable my FSAL to allow for this operation. Hi, Sorry for the late reply. As Frank mentioned in the previous mail, you might need implement above pNFS ops. Also you need to set pnfs_mds and pnfs_ds flags to true in the export structure. For FSAL_GLUSTER entire file will be present in the DS (no stripping is performed). If your FSAL does not store as file but as object please refer FSAL_CEPH (in which mapping of object to file is performed).If you have any clarification regarding FSAL_GLUSTER implementation, please reach us out via mail.

Turns out that it only looks for the shared objects under /usr/lib64/ganesha even though I specify the FSAL_Shared_Library. Am I doing something wrong?
