March 22, 20251 yr Hello, i have a problem with my unraid server running version 7.0.1. I run it on a lenovo PX4-400R with an Atom D2701, 2GB RAM, 2 1G onboard NICs and an addon intel X520 2x 10G-BasaeT Card I have bonded both 10G ports but unraid randomly disconnects from the bond and shows the both interfaces down. On the Switch both ports are shown as up. I have one 1G interface connected to another net and i can acces unraid after that over that interface. tried to down and up the bond interface but with no success Can anybody help to make it more stable? Right now i cannot use it in production and i am a little disappointed on spending the 49$ for the starter licence. i have attached diagnostics file.

March 22, 20251 yr Community Expert Solution I would guess this is the relevant part: Mar 21 16:05:06 SAN01 kernel: ixgbe 0000:04:00.0: 2.000 Gb/s available PCIe bandwidth, limited by 2.5 GT/s PCIe x1 link at 0000:00:1c.3 (capable of 32.000 Gb/s with 5.0 GT/s PCIe x8 link) You have put the Intel 10G card into a slot with single PCIe 2.0 lane. She needs at least 4 lanes PCIe 3,0 (or even 8 lanes? the line is not really clear about this) Fact is, the card is running in a mode "slow as a dog", it can never transfer 10G this way. I guess under heavy load it just gives up and shuts off. (Note that not all slots on your MoBo that MAY LOOK like beeing "large" also are electrically connected too. Look into your manual to see in which slot this card needs to be placed)
March 22, 20251 yr Author the problem accured under nearly no load. i have transfered 2 test vm disks before without a problem, did not notice slow perfomrance because the source files were on a 1G NAS. The problem accured in the night without load. but the pcie lane size is a good hint. i will try a dual 1G NIC
March 22, 20251 yr Community Expert there was another line in your logs that could point to trouble: Mar 21 16:05:26 SAN01 kernel: bond2: Warning: No 802.3ad response from the link partner for any adapters in the bond This means, the connected switch does not honor the bond! Look into it's config, try different bond modes (not all are supported by every vendor) or even drop down to "active backup" (which does not need switch support but also does not aggregate anything too). BTW... are you sure you know what you want? Even with a working 802.3ad bond, there will not be any speedup because every connection always just uses ONE card. Many connections maybe split among cards, but a single connection always only uses ONE of them. So in most cases "bonding" is nothing people really need or what pleases them...
March 22, 20251 yr Author the modinfo igxpe dont show the right version info. The newest intel drivers have the version 6.0.6 Intel® Network Adapter Driver for PCIe* Intel® 10 Gigabit Ethernet Network Connections under Linux* this error: Quote Mar 22 15:55:51 SAN01 kernel: ixgbe 0000:04:00.0: Adapter removed Mar 22 15:55:51 SAN01 kernel: ixgbe 0000:04:00.0: Warning firmware error detected FWSM: 0xFFFFFFFF Mar 22 15:55:52 SAN01 kernel: ixgbe 0000:04:00.1: Adapter removed Mar 22 15:55:52 SAN01 kernel: ixgbe 0000:04:00.1: Warning firmware error detected FWSM: 0xFFFFFFFF should go away with a driver version from 6.0.0 i think unraid uses an older version Edited March 22, 20251 yr by WASN
March 22, 20251 yr Author why do iget an output for "modinfo igxbe" but cant find the driver in tools->driver->all drivers?
