4/30/2014 meeting summaries:
NFSoRDMA developers bi-weekly meeting is to help organizing NFSoRDMA
development and test effort from different resources to speed up
NFSoRDMA upstream kernel work and NFSoRDMA diagnosing/debugging tools
development. Hopefully the quality of NFSoRDMA upstream patches can be
improved by being tested by a quorum of HW vendors. The NFSoRDMA issues
can be tracked and followed up in time.
Today's meeting covered:
1. NFSoRDMA test strategy and plan:
What NFS related software tools are available for functional and
performance test?
Chuck has created a wiki page for NFSoRDMA test. The wiki page covers
NFSoRDMA functionality, stress and performance test. Here is the link to
the wiki:
http://wiki.linux-nfs.org/wiki/index.php/NfsRdmaClient/Home#Submitting_patches
If you have any other test suggestions like scalability test, please
send to Chuck Lever.
How are we going to organize continuous testing resources:
Each of us have our own lab with different configuration, thus we could
have a better test coverage without purchasing/installing all vendors
hardware.
2. Helping others on problem report and follow up:
How to get help from the communities?
Problems should be reported on both linux-nfs and linux-rdma mailing
list. However some others found the problems they reported had been
ignored in the past. In order to better tracking NFSoRDMA bug report, we
have created NFSoRDMA linux-nfs.org bugzilla family, which will be
mirrored to liux-nfs, linux-rdma mailing list. Here is the link to
linux-nfs.org NFSoRDMA bugzilla:
https://bugzilla.linux-nfs.org/enter_bug.cgi?product=kernel
NFSoRDMA server component: svcrdma
NFSoRDMA client component: xprtrdma
Chuck Lever and Shirley Ma will help tracking issues on NFSoRDMA bugs.
This isn't guaranteed the bugs being assigned and fixed. Chuck Lever and
Shirley Ma will work on NFSoRDMA client side issues. But we still
couldn't locate resources to support NFSoRDMA server. This is an
outstanding issue.
3. Upstream NFSoRDMA status:
Anna Schumaker has created git tree to maintain all NFSoRDMA client
stable patches. It will be easy for maintainer to pull patches to
upstream. NFSoRDMA end users can use her git tree. Here is the link to
Anna's NFSoRDMA client git tree:
git://git.linux-nfs.org/projects/anna/nfs-rdma.git
Chuck Lever's NFSoRDMA linux-nfs.org git tree is for developers only.
All patches should be reviewed and tested before going to Anna's tree.
Here is link to Chuck Lever's git tree, check out nfs-rdma-client branch.
git://git.linux-nfs.org/projects/cel/cel-2.6.git
4. NFSoRDMA debugging and diagnosis tools:
ibdump is a ConnectX sniffing tool, which can be used to monitor
InfiniBand packets on the fabrics. wireshark is able to interpret these
packets in IB but not NFSoRDMA layer. A dissector is needed for NFSoRDMA
protocol. Yan Burman will look at how much work to create NFSoRDMA
dissector for wireshark.
Chelsio is also able to replicate packets to other interface for
wireshark to monitor. Steve Wise will help on finding how-to instruction.
Next meeting topics proposal:
1. Follow up the work has been discussed from this meeting.
2. Walk through some of the stories on pivotal, link is as below:

3. Invite some of the developers to discuss some of their requirements
and features.
Meeting time: one hour discussion every other Wed (next meeting will be
on 5/14). A reminder will be sent out to both linux-nfs and linux-rdma
