Anyone got SMB multichannel working on OS6?
Hi, I have old Ultra 4 Plus with OS6 6.10.8 connected on both 1Gbit ports to 2.5Gbit network switch (no teaming or bond configuration , just two separate adapters with two IP). PC is using a single ...
I made it work in OS6! I can now transfer single file with 1.7Gbit/sec from old NAS using single 2.5Gbit NIC and two NAS 1GBit NIC's. In order for multipath to work, you need two IP's on both sides: NAS and PC. If you have single NIC in PC, you need to give it two IP's. Then you need to go into Windows NIC advanced properties and enable RSS (you will need up-to-date driver for this). Then on NAS side, you need to add configuration to smb.conf:
interfaces = "192.168.0.4;speed=10000000000,capability=RSS" "192.168.0.5;speed=10000000000,capability=RSS"
server multi channel support = yes
And also add static routes to your PC (where two adresses are the two adresses of your PC NIC)
ip route add 192.168.0.222 dev eth0
ip route add 192.168.0.223 dev eth1
Reboot, check status in PowerShell with "Get-SmbMultichannelConnection" and that's it.
The Ultra4Plus does have two separate Marvell 88E8057 NIC controllers, so should be capable of multichannel (some ReadyNAS have a single dual-channel NIC) as long as the kernel supports it. Have you used ethtool to see if RSS is enabled and try to enable it if it's not? Even though standard Debian Jessie does have that capability, Netgear may have used an older Marvel driver that doesn't support RSS.
It seems that this Marvel driver does not support setting channels:
>>ethtool -l eth0
Channel parameters for eth0:
Cannot get device channel parameters
: Operation not supported
>>ethtool -i eth0
driver: sk98lin
version: 10.93.3.3 (03)
firmware-version: N/A
bus-info: 0000:01:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no
Can I update drivers without re-installing whole Debian linux?
