Proxmox cluster lost synchronization

Hello,
Today our cluster lost synchronization. Most of the nodes were shown as offline or unknown. The nodes were up but every node could see only itself and few other nodes.
Restarting the pve-cluster and corosync didn't help so we brought everything down and started them one by one.
For most of the hosts this worked. However if we start the last few of them they seem to be causing the other nodes to crash.
The log says that synchronization is started and few minutes later everything crashes down the same way. Disconnecting the hosts fixes the issue after few minutes.
Additionally few tasks for starting all VMs and containers and few tasks for starting single VMs left rinning and can't be stopped.

Any ideas how to bring the last hosts up are welcome.
Part from the syslog when the failure occures:

Make sure your nodes are synced up, otherwise it can lead to behavior like this.
 
Hello and thanks for the replay.
I made sure the time was correct but when I started one of the nodes everything crashed once again.
Below is the syslog of one of the working nodes for few minutes before the crash.

Is there any way to manually synchronize the db of the nodes?
 
Looks like a network issue then. Check your NICs, cables and switches.
Also update to the latest PVE 6.4 version at least.

What NIC models are you using? Is the firmware up-to-date?
 
Already checked the network part.
We are planning an update but this will take part when the cluster is back to its normal state.
Is there any way to manually sync the db between two nodes?
And also is there any way to manually kill this tasks - they are stuck forever an cant be stoped from the UI?

Do you mean pmxcfs? There's no need for that.
Could you provide the interfaces file (/etc/network/interfaces) for all nodes, as well as the corosync config (/etc/corosync/corosync.conf and /etc/pve/corosync.conf)?
 
Hello,
And thanks for the support. It seems that problem was caused by intermittent high network latency and corosync was unable to sync correctly.
In order to resolve the problem we deployed a private network for the cluster. Then we configured the interfaces and changed /etc/corosync/corosync.conf to use the private interface (done for every node). At the end we started the corosync.service on each node and the cluster was up and running once again.
Is there any way to create "backup" links for corosync?
Thank you.
