Stange problems with CentOS 7 and roundrobin runner
by Ingo Brand
Hello,
I am currently setting up a high available NFS server cluster with 2
nodes using pacemaker + corosync + drbd + flashcache.
The two nodes (media1 and media2) have 4 1G copper nics each.
I formed 2 teams:
team0: LACP with em1 and em2 connected to a switch for NFS services
team1: roundrobin with em3 and em4 and MTU 9000 directly connected with
copper patch cables for drbd sync
During my testing everything was working as expected. Then I started to
tranfer about 20TB from an old server to the new cluster. The copy
process was fine for about 32 hours. Then corosync and drbd started to
report errors on the roundrobin team1 interface (see logs at the end of
this email).
The drbd sync and corosync started to flap between states for several
hours on team1.
I checked the error counters with ifconfig and found a huge amount off
TX dropped packets on team1 of the drbd slave node media2.
There were NO other error counters raising but team1 on media2.
To make this a bit more clear:
- team1 on media2 (the drbd slave) showed raising TX dropped packets
- em3 and em4 on media2 (the physical interfaces of team1) did not show
any raising error counters.
- team1 on media1 (the drbd master) did not show any raising error counters.
- em3 and em4 on media1 (the physical interfaces of team1) did not show
any raising error counters.
I then thought maybe one of the two patch cables between the two
machines was not 100% ok. So I removed em4 from team1 on both machines:
"teamdctl team1 port remove em4"
The error counters stopped raising.
I thought: "Yeah! That cable must be broken!"
But just to make sure I really found the problem I re-enabled em4 on
both nodes:
"teamdctl team1 port add em4"
Ok, now both team1 interfaces had 2 links up again and the error counter
restarted to raise again.
I then stopped em3 on both nodes to force all traffic through em4:
"teamdctl team1 port remove em3"
And guess what? The error counters on team1 stopped raising!
So in short:
If I remove either one of the two physical interfaces from team1
everything is working without any errors. As soon as I enable both
physical interfaces the error counters start to raise.
After these tests I rebooted the slave node (media2) and added both
ports to team1 again (Have you tried turning it off and on again...).
After doing this, I now see TX dropped packets on the not yet rebooted
media1 team1 interface.
Why do I only see these errors on the team1 interface and not on em3 and
em4?
Currently the copy process of 20TB is still running. I think that if I
reboot media1 everything will work as expected again for some time
because it worked during my initial tests.
But I do think that I hit a bug in the teaming driver and the raising
error counters will come back.
Could anybody help?
Kind regards
Ingo

[PATCH] dbus: don't do <deny send_interface="..." /> in template dbus s. f.
by Pawel Wieczorkiewicz
Remove '<deny send_interface="..." />' directives from the dbus
config template, since they were removed from the main file as
well. The template file is used to replace the original dbus
config file with per user directives specified during compile
time.
This is a change originating from commit: cf24f96afb338d.

ccing mailing list.
Just please look at the subject line, looks like all test is squashed
there. Signed off is there. It should be in message body. Also, please
provide some patch description in message body (not subject). Subject
should just briefly tell what is going on.
Also, when you look at the patch, your editor is screwing up indentation.
Please set your editor correctly in order to not screw up indentation.
After that, it would be much more easier to review, and also possible to
apply.
I wonder how you don't see this...
Please see other patches in git history using "git show". They might help
you to format correctly.
I don't want anything abnormal. I just want sane patch. It is in fact
nothing hard. It is in fact very easy.
