Network maintenance

[RafaelDM]

Hello,

We are going to test the backbone networks of our infrastructure. The network wich may be down during 10 to 20 minutes.
Is it possible to temporarly disable the watchdog in order to prevent the nodes to reboot during this time ?

Thank you,
Rafael

Yes, you can stop the PVE HA services for that time.

First top the LRM on all nodes!

systemctl stop pve-ha-lrm

Once it is stopped on all nodes, stop the CRM on all nodes!

systemctl stop pve-ha-crm

One you are done, start them in the same order, first the pve-ha-lrm services, then the pve-ha-crm.

Hello,

I open this thread again, because we have to stop HA/Watchdog during network operations, and this solution don't work now.

When I stop the 2 services lrm and later crm they stop (dead) and come UP again after a few minutes :
I use this command :
systemctl stop pve-ha-lrm
systemctl stop pve-ha-crm

Is there a way to really stop these services or do i miss something ?
Best regards,
Rafael
