iSCSI and Network Bonding
Good Evening Everyone, Just wanted to reach out to the guru's here as I am stumpped at the moment. I have a ReadyNas 314 connected to a TP-LInk TL-SG108E switch. This switch supports the provision o...
Good News Everyone,
I have figured it out !! (I am pretty excited!). The issue seemed to be with the iSCSI setup on the ReadyNas. I went into the iSCSI settings and within the properties of the group the 'Dedicated Link' was set to 'Any'. Changing this to "bond0:x.x.x.x" completely solved the problem.
In answer to your question acwdc, my SMB settings were as follows; Enable SMB (checked), Legacy Windows Discovery (checked), SMB3 Transport Encryption (Configured Globally - Enabled).
Hope this helps someone else out there. I really appreciate everyones help with this - a big thank you !!
Kind of wondered what would be the difference between ANY and the dedicated bond ID. Anyhow, it world now :)
Cheers,John
or use standard IEEE 802.3ad. I think the tplinks use source/dest by mac address as a hash algorithm.

No, that won't work. The TL-SG108E only supports static LAGs.
If you are using jumbo frames on the NAS or in the PC, then try turning them off.
think the tplinks use source/dest by mac address as a hash algorithm.
In general, the decision about what packets to put on what link is made by the sender, and is not negotiated. So the switch often does use a different algorithm than the NAS. The hash shouldn't affect connectivity, but it can affect performance.
Good morning everyone, thanks so much for the replies. I think what I may be better off doing is getting another switch that fully supports IEEE 802.3ad.
When enabling Round Robin do I still need to set up a LAG group on the switch or is there any switch configuration that is required at all?
Cheers,John

I have switches that do support it. The performance gains are usually marginal, unless you have a lot of clients running simultaneously. So I wouldn't get a new switch if I were in your position.

Yes.
But if you try ALB or TLB, then you don't use a LAG group for those.
G'day StephenB,
Thanks so much indeed. You know... really I might just discard the whold idea. Seemed like a good idea at the time, but as you mentioned really not going to get much of a performance boost.
It will have to do.
Cheers guys and have a great dayJohn
hi StephenB,
Yes that's correct, my mistake, TL-SG108E only supports static LAGs.
Homith, i've got TPlink switches with LAGs configured (static ones... I did not realise this). Just now I've connected a RN312 to one switch and setup a team with XOR/Lv2 only. It works. The only thing I would suggest is to set the config up on the switch and NAS first, then connect the second NIC of the NAS to the switch.

G'day Acwdc,
Thanks so much for your reply on this - I do appreciate it. The issue I am confronted with is more to the fact that I can configure LAG on the switch, and set up the ReadyNas to a new bond (XOR/Lv2) and can still receive a ping response from the ReadyNas. I can selectivly disconnect one ethernet port at a time and the ping is constant.
The issue I am facing is that the Windows iSCSI Initiator can no longer reconnect to the target on the ReadyNas and the ReadNas is no longer visable within the Network Neighborhood. Very odd as the ping is constant.
Driving me batty hehe :)
CheersHomith,
Then, I do not thing you got issues with LAGs. Works on different network layer. I think its got to do with the SMB Master Browser. Have you have Legacy Windows Discovery enabled under the SMB settings of the NAS (i.e. SMB1)? Are all hosts local in your network?
