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
