For the NVMe-oF TCP transport in SPDK
by Yang, Ziye
Hi all,
The NVMe TCP transport is just merged in SPDK master branch, and there are still some works to harden and make it better. For example, currently we need do lots of interoperability test with Linux kernel host/target to guarantee the functionality first . If you submit patches related with this TCP transport, could you also add me as the reviewer (You can search my name in review.gerrithub.io)? Then I will not miss your patch (though I will keep looking at the patches with some filters).
Thanks.

Hi everyone-
I'm running a dual socket Skylake server with P4510 NVMe and 100Gb Mellanox CX4 NIC. OS is Ubuntu 18.04 with kernel 4.18.16. SPDK version is 18.10, FIO version is 3.12. I'm running the SPDK NVMeoF target and exercising it from an initiator system (similar config to the target but with 50Gb NIC) using FIO with the bdev plugin. I find 128K sequential workloads reliably and immediately seg fault nvmf_tgt. I can run 4KB random workloads without experiencing the seg fault, so the problem seems tied to the block size and/or IO pattern. I can run the same IO pattern against a local PCIe device using SPDK without a problem, I only see the failure when running the NVMeoF target with FIO running the IO patter from an SPDK initiator system.
Steps to reproduce and seg fault output follow below.
Start the target:
sudo ~/install/spdk/app/nvmf_tgt/nvmf_tgt -m 0x0000F0 -r /var/tmp/spdk1.sock
Configure the target:
sudo ./rpc.py -s /var/tmp/spdk1.sock construct_nvme_bdev -b d1 -t pcie -a 0000:1a:00.0
sudo ./rpc.py -s /var/tmp/spdk1.sock construct_nvme_bdev -b d2 -t pcie -a 0000:1b:00.0

Community meeting and use of new conf tool
by Luse, Paul E
FYI we had 19 people on this morning's call and nobody had any issues connecting, with audio, with sharing or with random music playing in the background (LOL).
After we try this in next week's Asia time one call we'll officially declare it out new conf tool and update the website
Thanks!!!

All,
I'll send out a few reminders for tomorrow's call since a couple of folks missed them last time. We're not "officially" changing over just yet because we couldn't try the service last week with the Asia call because it was cancelled due to the holiday in the US.
Anyway, below is the info for tomorrow's call. I'll put it on IRC as well.
Thanks!

For the Chandler testing pool
by Yang, Ziye
Hi all,
These days, I found that the Chandler testing pool is very busy. When in PRC time zone, there are lots of patches are waiting to be tested. For example today, from now, I see 27 patches are in the list. According to the testing process, each will waste 12 minutes, it means that the total time will be about 324 minutes, which means that if you submit a patch this time, you need to wait at least 5.5 hours (after 14:30, you can see the results). Since we are global team, Poland team will nearly start work at 4:00 PM. So it left less time for PRC in the daily time. Usually, I will get the results of my patches after my working time. So my question is that: Can we reduce this time since currently the testing time is too long?
PS: Why we need the Chandler test pool? Since it has different environments, you cannot verify your patch in the single local test environment.
Thanks.
Best Regards

retrigger inconsistencies
by Luse, Paul E
Last week Jim had mentioned a few cases where Jenkins failed to pick up a retrigger and it seems like those might be understood (missing an event, need to use REST API to poll). I ran into one today on the CH TP and although we're going to retire that system here soon it might be good to understand how this one was missed as I was under the impression that it was already polling GH. See https://review.gerrithub.io/c/spdk/spdk/+/433727

spdkcli.py in weird state
by Chuck Tuffli
Hi
Using the latest spdkcli.py from git, I can get it into a weird state where
the ll command only displays:
'uuid'
after adding an NVMe drive to a subsystem's namespace. The below process
works correctly if the configuration uses a Null bdev instead of an NVMe
bdev, but perhaps I'm doing something wrong.
$ sudo ./nvmf_tgt --wait-for-rpc
$ sudo -sH scripts/spdkcli.py
