[PVE-User] Recurring crashes after cluster upgrade from 5 to 6

[Alexandre DERUMIER]

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
