Stange problems with CentOS 7 and roundrobin runner
by Ingo Brand 07 Sep '16

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 This is the used network config of team1: media1: cat /etc/sysconfig/network-scripts/ifcfg-team1_slave_0 # Generated by parse-kickstart NAME=team1 slave 0 TEAM_MASTER=team1 DEVICETYPE=TeamPort DEVICE=em3 ONBOOT=yes UUID=b7026c5b-e9cd-457c-93d2-a2799361ed90 cat /etc/sysconfig/network-scripts/ifcfg-team1_slave_1 # Generated by parse-kickstart NAME=team1 slave 1 TEAM_MASTER=team1 DEVICETYPE=TeamPort DEVICE=em4 ONBOOT=yes UUID=fbe5bc56-95f5-4f9e-a5ea-ab6b6f5e5b50 cat /etc/sysconfig/network-scripts/ifcfg-team1 # Generated by parse-kickstart UUID=4e0090cd-32d3-4c5b-be23-9f53083da4dd NAME="Team connection team1" TEAM_CONFIG="{\"runner\": {\"name\": \"roundrobin\"}}" GATEWAY= IPV6_AUTOCONF=yes BOOTPROTO=none DEVICE=team1 MTU=9000 TYPE=Team ONBOOT=yes IPV6INIT=yes DEVICETYPE=Team IPADDR0=192.168.101.31 PREFIX0=24 DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6_DEFROUTE=yes IPV6_PEERDNS=yes IPV6_PEERROUTES=yes IPV6_FAILURE_FATAL=no media2: cat /etc/sysconfig/network-scripts/ifcfg-team1_slave_0 # Generated by parse-kickstart NAME=team1 slave 0 TEAM_MASTER=team1 DEVICETYPE=TeamPort DEVICE=em3 ONBOOT=yes UUID=bfd8e77e-7eb8-47ea-ab7e-95286e073202 cat /etc/sysconfig/network-scripts/ifcfg-team1_slave_1 # Generated by parse-kickstart NAME=team1 slave 1 TEAM_MASTER=team1 DEVICETYPE=TeamPort DEVICE=em4 ONBOOT=yes UUID=93c5dfd8-3b81-4d1e-8ba9-c46f8daceb1a cat /etc/sysconfig/network-scripts/ifcfg-team1 # Generated by parse-kickstart UUID=79c843db-996c-41e4-9ee5-2a8f3da244ed NAME="Team connection team1" TEAM_CONFIG="{\"runner\": {\"name\": \"roundrobin\"}}" GATEWAY= IPV6_AUTOCONF=yes BOOTPROTO=none DEVICE=team1 MTU=9000 TYPE=Team ONBOOT=yes IPV6INIT=yes DEVICETYPE=Team IPADDR0=192.168.101.32 PREFIX0=24 DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6_DEFROUTE=yes IPV6_PEERDNS=yes IPV6_PEERROUTES=yes IPV6_FAILURE_FATAL=no Here are some system logs from both machines: ============================================================ media1: ============================================================ Nov 6 02:31:27 media1 corosync[3657]: [TOTEM ] Incrementing problem counter for seqid 412041 iface 192.168.100.31 to [1 of 10] Nov 6 02:31:29 media1 corosync[3657]: [TOTEM ] ring 0 active with no faults Nov 6 02:31:29 media1 corosync[3657]: [TOTEM ] Incrementing problem counter for seqid 412047 iface 192.168.100.31 to [1 of 10] Nov 6 02:31:31 media1 corosync[3657]: [TOTEM ] ring 0 active with no faults Nov 6 02:32:51 media1 corosync[3657]: [TOTEM ] Incrementing problem counter for seqid 412315 iface 192.168.101.31 to [1 of 10] Nov 6 02:32:53 media1 corosync[3657]: [TOTEM ] ring 1 active with no faults Nov 6 02:32:53 media1 corosync[3657]: [TOTEM ] Incrementing problem counter for seqid 412319 iface 192.168.101.31 to [1 of 10] Nov 6 02:32:54 media1 corosync[3657]: [TOTEM ] Incrementing problem counter for seqid 412321 iface 192.168.101.31 to [2 of 10] Nov 6 02:32:55 media1 corosync[3657]: [TOTEM ] Decrementing problem counter for iface 192.168.101.31 to [1 of 10] Nov 6 02:32:56 media1 corosync[3657]: [TOTEM ] Incrementing problem counter for seqid 412325 iface 192.168.101.31 to [2 of 10] Nov 6 02:32:57 media1 corosync[3657]: [TOTEM ] Decrementing problem counter for iface 192.168.101.31 to [1 of 10] Nov 6 02:32:58 media1 corosync[3657]: [TOTEM ] Incrementing problem counter for seqid 412327 iface 192.168.101.31 to [2 of 10] Nov 6 02:32:59 media1 kernel: drbd r0: PingAck did not arrive in time.

If it's not in the correct format, I'm sure you can extract the patch from what I've sent you. 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.
