It now handles mirrored Data Servers (= DSs) and recovery of a failed mirrored DS while the service is operational. It handle non-pNFS clients (such as NFSv3 mounts) via having the MetaData Server act as a proxy for Read/Write operations. For pNFS capable NFSv4.1 clients, the Read/Write operations are done direct= ly on the appropriate DS(s), avoiding the MetaData Server (which act like a no= rmal NFS server except for pNFS capable clients). If you are interested in more information or doing testing, see: http://people.freebsd.org/~rmacklem/pnfs-planb-setup.txt I hope that this should be ready for head/current with some additional test= ing. I will post here asking the "collective" about this when I think it is read= y. If there are any volunteers on the doc side who would like to turn the abo= ve text file into a useful document, that would be greatly appreciated. Good luck with it, if you test it, rick=
