New Version 2.4.4 - Interface Error --> aq_add_macvlan err -53, aq_error 14
-
We experienced a hard reboot during VLAN configuration on the slave node.
Looks like problem is only occuring when reconfiguring interfaces.I'll keep you updated

--- trap 0, rip = 0, rsp = 0, rbp = 0 ---Regarding IXL driver, I noticed that a 1.11.20 version was released in september but but download page wasn't displaying the good driver (IAVF instead of IXL).
So I emailed Intel today and they fixed the issue and we can now download the 1.11.20 version.
We will try it tomorrow. -
So here we are after a lot of trial:
-
we know and are sure that reconfiguring interface capabilities (TSO) while transmitting trafic is what is causing queue hang (like explained in the FreeBSD ticket)
-
we know adding vlan with 1.9.9k produce a queue hang and a mac vlan error
-
we know IPV6 was causing hang, but we did not test it again in the last setup (see below)
-
the hard reboot is caused by an issue not directly related to the interface problem but a result of a lock when a queue hang
-
we did compile and install version 1.11.20 of the IXL driver and we did remove the execution of our script that was removing HWVLANTSO at boot because when it was executed the NIC was already transmitting trafic and we had one or two queue hung at boot. This would cause issues later on.
-
we did test adding vlan this morning and nothing bad happened, no error message, no queue hang,
So, we start a new phase of monitoring of how it is going.
-
-
A quick FollowUP running 1.11.20 :
- 9 days uptime
- no error so far.
- throuhput is good, no issue
- we added 6 new vlan in the last 9 Days and everything works as expected for the moment.
- we did test multiple master/slave failover/failback, no issues
I'll continue to keep you informed.

Please add that info to the bug report if you have confirmed it.

@Juve could you add those intel to the ticket, Stephen mentioned?
It would provide additional help/info.also @stephenw10 if that driver release seems to solve the problem, how are chances that it be included in a 2.4.5 release? As we're currently having information from two customers they are seeing similar problems (one with "no response - dead" pfsense when adding VLANs, one having a reboot with queue and VLAN errors shown), that would be a great thing.
best regards

If it's in 11 stable it would likely make it into a 2.4.X release. The drivers in 12 look to be significantly different, I'm not sure that could be brought back.
Steve

I did update the ticket :-)
-
Quick update:
50 days uptime, no error so far.
Looks like the driver was the issue. -

Looks like the driver was the issue.What were the latest changes you were running? Latest driver as you wrote (1.11.20) and HWVLANTSO removal?
If so, any chance @stephenw10 to bring that driver version into the mix for the upcoming 2.4.5?
-
It is still super stable.
The only two things we did at the end are:
- use the latest driver
- use failover LAGG and not LACP lagg (but we did not test LACP with latest driver so we can't confirm is is not working with it)
no VLANTSO removal etc.
-
Is anyone still seeing this with the 1.11.9 driver in 2.4.5?
Steve
-
@stephenw10
with 2.4.5 no error (LACP LAGG, 15 VLANs) -
Ah, good. We were trying to replicate it in 2.4.5 and have not done so.
If anyone is seeing it though please let us know the steps required.

Hi, I think I can reproduce this problem with pfSense version 2.4.5-RELEASE-p1 (amd64) and native driver 1.11.9-k.
We have ~45 vlans on one of the interfaces, adding a new vlan on this interface leads to impossibility to ping / reach the system on any of the sub-interfaces related.
Console prompts "queue appears hung" messages, reboot seems to be the only solution to get the system working again (new vlan included).
I did set net.inet.tcp.tso = 0 via Advanced / System tunables : the messages don't show anymore, but still the same problem (system unreachable when adding vlan, reboot needed).Tested on X710 and X722 Intel NICs, Supermicro server.
I will test upgrading the Intel driver and/or VLANTSO removal, keep you informed.
Don't hesitate to ask if I can provide more info.
Have a nice day,
Fabien -
Are you seeing the error messages:
Interface Error --> aq_add_macvlan err -53, aq_error 14Or just the 'queue appears hung' logs?
Steve
-
@stephenw10 Hi !
Just the 'queue appears hung' and server unreachable on the interface.
