[pve-devel] corosync problems - need help

Yes, I need to do it on all nodes.



I have done more invesgations, and now I can reproduce the problem 100%

The problem seem to come from a specific node: kvm11

When I start cman on this node,

I have :
pmxcfs[31484]: [status] notice: cpg_send_message retry XX

on all other nodes

Same hardware than other nodes, I need to check the network layer.


On the faulty node, I see also some pmxcfs segfaults in dmesg

[976776.602200] pmxcfs[3130]: segfault at 7ff1dcadef08 ip 00007ff1dcadef08 sp 00007fffd89cfe68 error 15
[977517.260211] pmxcfs[4947]: segfault at 1956b00 ip 0000000001956b00 sp 00007ffff3b109e8 error 15

I am curios - you have done that on all nodes, or only on the failing 2 nodes?
