The Network File System (NFS) has existed in one version or another since 1985. The OpenSolaris implementation includes support for NFS versions 2, 3 and 4. NFS version 4 is the area where most of the development activity exists. There is ongoing work within the IETF in interpreting the current NFSv4 specification and defining extensions or minor versions for NFSv4.

The very nature of NFS, sharing of filesystems, has led to the development of an NFS community that consists of the various platform implementations. Once a year, that community comes together to do interoperability testing at Connectathon'™'.

tdh - ds_addr_t is now da_addrlist_t

Oct 13, 12:57 PM

As a group, we decided to change ds_addr_t to ds_addrlist_t to avoid confusion with struct ds_addr . The OpenSolaris gate has those changes already. Originally posted on Kool Aid Served Daily ...

tdh - Restarting with mds_gather_devs

Oct 12, 7:11 PM

Time to pick back up on that analysis, but remembering that ds_addr is different than ds_addr_t . mds_gather_devs Note, we are in usr/src/uts/common/fs/nfs/nfs41_state.c ... So mds_gather_devs does ...
