[pve-devel] corosync problems - need help

Ok, sorry. ( I thinked about this because in log I was seeing increment up to around 65000, then no more log ).


What I have done yesterday :

- update all nodes to 3.10 kernel
- upgrade openvswitch to 2.3.0   (I had see an high cpu bug, and 2.3 fix it).


But don't help.

I have been able to bring back this node in the cluster for around 5min, then It begin to hang again.


Today, I'll try to shutdown corosync on all servers,

then start corosync on this node and join other nodes.

(I want be sure that it's not because I have 2 more nodes in my cluster)


I'll keep you in touch

First, int is 32bit. Second, interger overflow does not raise an exception in C.
So that cannot be the reason.
