How frequently should I patch and reboot?

[FORCED-INDUCTN]

Hello,

I know it's kind of a dumb question, but any guidelines on how often I should reboot the servers/let the servers run after doing updates? Any risk in updating all the PVE software for a couple months and then rebooting the server only a couple times a year? I have the servers in clusters so down time is not a big issue just wondering how to keep them healthy .

Thanks

Hi, I think it depend if you use openvz or kvm.

Openvz updates are made in kernel, so you need to reboot to get them.
For kvm, you can reboot when you really need it, or if they are an hardware/driver bug. (I reboot my servers around each 6month).
You can do kvm update and proxmox updates without rebooting the server.

Thanks for the reply spirit!
I do run KVM exclusively. Thank you for the clarification, and reassurance. I'll try to plan for bi/tri-yearly maintenance periods.

Thanks again,
