Hi Alexandre,
We encouter exactly the same problem as Laurent Caron (after upgrade
from 5 to 6).
So I tried your patch 3 days ago, but unfortunately, the problem still
occurs...
This is a really annoying problem, since sometimes, all the PVE nodes
of our cluster reboot quasi-simultaneously !
And in the same time, we don't encounter this problem with our other
PVE cluster in version 5.
(And obviously we are waiting for a solution and a stable situation
before upgrade it !)
It seems to be a unicast or corosync3 problem, but logs are not really
verbose at the time of reboot...
Is there anything else to test ?
Regards,
Hervé

Hi,
a patch is available in pvetest
http://download.proxmox.com/debian/pve/dists/buster/pvetest/binary-amd64/libknet1_1.11-pve2_amd64.deb
can you test it ?
(you need to restart corosync after install of the deb)

Objet: [PVE-User] Recurring crashes after cluster upgrade from 5 to 6
Hi,
After upgrading our 4 node cluster from PVE 5 to 6, we experience
constant crashed (once every 2 days).
Those crashes seem related to corosync.
Since numerous users are reporting sych issues (broken cluster after
upgrade, unstabilities, ...) I wonder if it is possible to downgrade
corosync to version 2.4.4 without impacting functionnality ?
Basic steps would be:
On all nodes
# systemctl stop pve-ha-lrm
Once done, on all nodes:
# systemctl stop pve-ha-crm
Once done, on all nodes:
# apt-get install corosync=2.4.4-pve1 libcorosync-common4=2.4.4-pve1
libcmap4=2.4.4-pve1 libcpg4=2.4.4-pve1 libqb0=1.0.3-1~bpo9
libquorum5=2.4.4-pve1 libvotequorum8=2.4.4-pve1
Then, once corosync has been downgraded, on all nodes
# systemctl start pve-ha-lrm
# systemctl start pve-ha-crm
Would that work ?
Thanks
