Hello List,

i have a 3 Node Cluster with ceph.
They are connected to each other with unicast.

node08: pve-manager/5.3-5/97ae681d (running kernel: 4.15.18-9-pve)
node09: pve-manager/5.2-9/4b30e8f9 (running kernel: 4.15.18-7-pve)
node10: pve-manager/5.2-10/6f892b40 (running kernel: 4.15.18-7-pve)

Those nodes "freeze" from time to time since 29.07.2018:
29.07.2018 | node09
07.08.2018 | node08
21.08.2018 | node10

16.10.2018 | node09
05.12.2018 | node08

I have the EXACT 3Node Hardware running Proxmox 4.4 which does not have those problems.
Until now, i thought its a Kernel/Nic driver problem. My thread is here:
https://forum.proxmox.com/threads/periodic-node-crash-freeze.46407/

However, i seem to have quite a few corosync/totem log entries like this:

node09 corosync[5290]: [TOTEM ] Retransmit List: 18f46c9
node09 corosync[5290]: notice [TOTEM ] Retransmit List: 17ae461

My healthy Cluster still running on proxmox 4.4 does not have those problems. But maybe because the load is not the same?!

Here comes my real question:
1.) Did node08 die or:
Did node08 freeze AFTER some fence magic happened?
2.) Why does node08 not log any totem/corsync retransmit stuff?
3.) My heartbeats run over the SAN/Ceph net. Thats okay, right?
4.) is this some weird unicast problem? Would Multicast fix that?
5.) can i test/benchmark my UDP Unicast somehow like with omping?

Here are the logs from my last crash-freeze of node08:

Thanks a lot,

1.) Did node08 die or:
Did node08 freeze AFTER some fence magic happened?
2.) Why does node08 not log any totem/corsync retransmit stuff?
3.) My heartbeats run over the SAN/Ceph net. Thats okay, right?
4.) is this some weird unicast problem? Would Multicast fix that?
5.) can i test/benchmark my UDP Unicast somehow like with omping?
1. it was most likely fenced.
2. it probably couldn't log anything anymore.
3. Corosync (and Ceph for that matter) needs low latency and any other traffic interferes. Put it on its own physical network.
4. Unicast produces way more traffic and eats way more resources then multicast. Check your switch load. Better use multicast.
5. omping is able to check both, multicast and unicast.
 
Hello,

i am still struggling with those random Node Freezes/Crashed.
I run a 3 Node cluster with Unicast (NO SWITCH) in a full meshed network.

uMFzZxS.png


I think i was abele to reproduced the problem with a VMWare 3Node Cluster Setup by setting some packet loss on the corosync network. The fencing jumps in and i get those @@@@@@@@ in the logs.

I then switched my corosync network away from the ceph/san network.

CEPH/SAN: 10.15.15.0/24 (10Gbit dedicated just for ceph)
COROSYNC: 10.15.16.0/24 (10Gbit dedicated just for corosync)

I read somewhere: never run corosync on the san/ceph network. I also changed the corosync token to 8000 (8 seconds).

But i sill get those:
corosync[1861153]: notice [TOTEM ] Retransmit List: 23a3c4 23a3c5
errors from time to time. No crash/fencing so far. Here are the numbers of Retransmit errors after i put corosync on a dedicated network:


Node08:

On node09 i got some Retransmit errors today about 10:38:47.
So here are the logs from 10:37 and 10:38 using grep like:

I was told i can test uniccast with omping, but i get:

root@node09:~ # omping -c 10000 -i 0.001 -F -q 10.15.16.9 10.15.16.10
omping: Multiple local interfaces (eth5 and eth4) match parameters.
=> obviously on a full meshed unicast network
 
Hello Alwin,

that wiki link seems new to me. But yes, i use "Method 2"
I think there was a official proxmox unicast howto which described Method 2. But i cant find it anymore.

Will Method 1 (multicast) fix my problem?

Thanks,
Mario
