How Can I Help with the new TRUENAS / 100G testing?

I booted the desktop into windows 10 (21H1 build 190493.1348) and verified that windows saw the adapters as RDMA enabled

Get-NetAdapterRDMA

Name                      InterfaceDescription                     Enabled     PFC        ETS
----                      --------------------                     -------     ---        ---
100G_1                    Mellanox ConnectX-5 Ex Adapter           True        False      False
100G_2                    Mellanox ConnectX-5 Ex Adapter #2        True        False      False

I then ran the following against KSMBD:

diskspd.exe -b8M -c20G -d60 -L -o8 -Sr -t16 -W10 -v u:\iotest.dat

which resulted in approx. 32Gbit of traffic

I then enabled all KSMBD features:

sudo ksmbd.control -s

sudo ksmbd.control -d all
[ksmbd.control/700357]: INFO: b] [auth] [vfs] [oplock] [ipc] [conn] [rdma]

cat /sys/class/ksmbd-control/debug
[smb] [auth] [vfs] [oplock] [ipc] [conn] [rdma]

sudo ksmbd.mountd

Same Results and did not see RDMA used, so to ensure I’m reading the cryptic bracket [ ] system correctly, I ran it again after flipping the features:

sudo ksmbd.control -s
sudo ksmbd.control -d all
[ksmbd.control/705724]: INFO:  auth vfs oplock ipc conn rdma

cat /sys/class/ksmbd-control/debug
smb auth vfs oplock ipc conn rdma

sudo ksmbd.mountd

Once again same result.

I’ll test Samba and Multichannel later this weekend,
Brian
