Hi Quanli Gui, The object-based pnfs server is based on the exofs filesystem which is in the mainline tree, plus a few patches in the linux-pnfs git tree, available in the pnfs-all-latest branch: e24ff7c pnfsd-exofs: pnfs objects server XDR functions 9c0cd62 pnfsd-exofs: Add pNFS export support 3b8ef79 pnfsd-exofs: get_device_info implementation. cea15bf pnfsd-exofs: Recall layouts on truncate 835e61b pnfsd-exofs: layoutreturn pnfs-obj information decoding d01493f SQUASHME: pnfsd-exofs: convert to new pnfs-submit changes Boaz (Cc'ed here) is the GUI who implemented most of it so he'd be the best person who could help you if you have any questions. See the following documents in the linux tree for setting up exofs: Documentation/filesystems/exofs.txt Documentation/scsi/osd.txt Once exofs is set up on the server and is exported with the pnfs export option and the obj layout driver is set up on the client (including attaching to all OSDs) you just need to mount the MDS the same way you would do for pnfs over nfsv4.1 files. See also the do-* scripts in the open-osd git tree for practical examples: http://git.open-osd.org/gitweb.cgi?p=open-osd.git;a=tree Regards, Benny On 2011-04-11 06:08, quanli gui wrote: > > > ---------- Forwarded message ---------- > From: *quanli gui* <gqlxj1987@xxxxxxxxx <mailto:gqlxj1987@xxxxxxxxx>> > Date: 2011/4/11 > Subject: [pnfs]how to use object-based pnfs > To: linux-pnfs <linux-nfs@xxxxxxxxxxxxxxx > <mailto:linux-nfs@xxxxxxxxxxxxxxx>> > > > pNFS has object layout, in the linux source code, we found that there > are only some source code on the client, for example, in > fs/nfs/objlayout.
