RN528 Bond interface bond0 has slave interface eth0 offline
This keeps happening, started two weeks ago and happens 20 times per day: “Bond interface bond0 has slave interface eth0 offline.“ RN528 and RN214 are both bonded through switch XS716E using LACP, c...
Thanks, I looked at the “logs” tab (not a zip file though??), doesn’t say anything useful. I’m not sure where to fetch that zip file from. With dual ETH on both PC and NAS the speed is closer to 2 Gbps than 1 Gbps so there is some benefit. Also, as noted this has been Rick solid for a year now. Nothing has been physically moved, just OS upgrades as they come along. Sorry, yes Both NAS’s are on 6.10.3. I can tear down the bonding but it was some learning/work to get it configured and stable, hate to go through that again. Frustrating.

There's a download button on the right of the the logs tab. That will download a zip file that has a lot more information than you see on the log tab.

Gigabytes per second? How are you measuring the speed?
Speeds quoted are gigabits/sec of course. Monitoring speeds with simple Windows File Explorer transfers.
Offline issue has been resolved, turned out to be a serious Orbi 11ax bug that has just been patched. Devices have remained fully online for over a week now since the patch.
Thanks for the assistance with log files too, good for future reference.

Then you are getting two gigabits/sec over a 10 gigabit bonded interface (5x to 10x faster, depending on the bonding mode in the NAS and the PC). So the bonding in the NAS isn't doing anything to improve your performance.
It does no harm though, and I'm glad that you have it working again.
FWIW, I am getting faster speeds without bonding between an RN526x and a Windows PC with a single Asus 10Gbase-T card - though I'm still not saturating my 10Gbase-T connection. The PC is several years old, and I think I'm running into it's performance limits.
Thanks, let me update you on my numbers. I have 2 NAS machines running static LAG, an RN214 with 2 x 1GbE and an RN528 with 2x10 GbE. Both connected to an XS716E switch, which is also connected to my PC running the Intel X500-T2 dual 10GbE NIC card. The NAS are programmed for "Round Robin" and the switch is programmed for static LAG pairs on specific ports.
Previously I was able to pass files to the RN214 at around 1.7-1.8 Gbps, which was what I was referring to in my earlier comment. This morning I just repeated a file transfer to/from the PC, and saw 1 Gbps both directions. At this time, static lag isn't doing anything, as you noted. I need to re-investigate I guess. From memory, I thought I also achieved >10 Gbps on the RN528, but it's been too long now so am not sure anymore.
The RN528-to-PC transfer was about 750 MB/s or around 6 Gbps. The PC-to-RN528 transfer was around 600 MB/s or 4.8 Gbps. Neither are any better than just a single 10GbE cable, as you noted. My PC is a Dell XPS8900 / Core i7/6700 with 64GB DDR4-2166 and a 1TB Samsung Evo Plus NVMe drive. Basically, best I can do with that machine.
Tried BlackMagicDesign HD Benchmark on the RN528, it pumps out 590 MB/s (4.7 Gbps) in both directions. Meh.
I just built a brand new Threadripper machine, using MSi Creator TRX40 Motherbaord, AMD Ryzen 3970X processor, 128GB DDR4-3200, and Seagate 520 1TB PCIe4.0 SSD. Thing weighs a ton, and I hoisted it upstairs away from my NAS at present. I plan to bring it back down and see how it does with the 10GbE link. It has Aquantia 10GbE built-in and also supports the latest 20 Gbps USB 3.2 2x2 standard, so I know this system isn't throughput-limited. Benchmarks are insane. Will post some results when I get to it.
I think what I learned from all this is that Ethernet channel bonding is a marketing gimmick. About the only thing it's good for is a bit of redundancy, and maybe helpful in a larger IT setting when certain routes are getting choked by too much traffic. I guess, anyway. All I know is that the dream of 20 Gbps over the RN526 is just that... a dream. For now anyway.
