Just to elaborate on "It never went anywhere" part, in case someone is interested in picking up the patch that Robert Gordon pointed to (http://cr.opensolaris.org/~danhua/webrev/onnv-clone.patch.).
The prototype for the NFS v3 client provider was done by Danhua Shao. It was working and also went through a code review process on nfs-discuss alias. The provider and the probes were demonstrated to work as expected. The key issue in the current provider design is the use of tsd_set and tsd_get functions in order to get a handle on RPC xid where the probes get fired. The problem is that we need a reasonable way to harvest the RPC xid in the higher level nfs functions. As of now, the design uses tsd_set and tsd_get routines. I believe that there is high overhead associated with the use of these functions. At the time this work was done, we did not come out with a more appropriate approach to harvest RPC xid values. I am also attaching the written description of NFSv3 client provider specification, which was posted earlier on these email aliases when the work was being done actively. -Piyush -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
