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.
Today's meeting notes:
1. Flesh out the process for testing and reviewing upstream patch sets:
What kind of test cases to run?
The upstream patch sets are required to test and pass functional test
suites. In long run, performance test suites will be required. The
performance test suites will be added later. Link to NFSoRDMA test wiki:
http://wiki.linux-nfs.org/wiki/index.php/NfsRdmaClient/Home#Submitting_patches
How would linux-nfs git tree help NFSoRDMA patch sets upstream to
mainline kernel?
Steve Wise will create linux-nfs NFSoRDMA server git tree with the help
from Anna Schumaker. Chuck Lever's client branch git tree includes all
client patch sets to be tested. Anna Schumaker maintains all client
patches to be pulled into upstream which have passed the test suites
(Sign-off: Tested-by). Steve Wise will create a branch to include both
client and server patch sets in case you use the same node for both
client and server.
How these tests to be done?
Each developer has his/her own hardware to test before submitting the
patch sets. IOL has a broad variety of hardware, Rupert Dance would
check how they can help in additional to OFED stack test. The test build
process will be defined later.
2. Identify a long term resource for maintaining the linux NFSoRDMA server
Oracle has allocated resource to support NFSoRDMA client. Linux
community needs funds to support NFSoRDMA server. There are engineer
resources but not the money. Any third parties are interested in
supporting NFSoRDMA server?
3. Follow ups from last meeting:
NFSoRDMA debugging and diagnosis tools?
Yan has started to look at NFSoRDMA dissector. Chelsio packets can be
monitored when turning on switch port mirroring.
Chuck has created linux-nfs bugzilla for NFSoRDMA: server component is
"svcrdma", client component is "xprtrdma" . Here is the link for you to
check/submit bugs
https://bugzilla.linux-nfs.org/
4. NFSoRDMA visualization validation:
Yan and Shirley are working on validating ConnectX SRIOV on both Xen and
KVM. They hit couple issues which need further debugging.
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
