[SOLVED] Updates and Reboots


Jan 9, 2019
Harrisburg, PA
Happy Friday everyone. Regarding updates, I see that 5.3-9 is in the repos and I've applied it to all my nodes:

The following packages will be upgraded:
libcurl3 libcurl3-gnutls libpve-common-perl libpve-guest-common-perl libpve-storage-perl pve-container pve-docs pve-libspice-server1 pve-manager qemu-server
10 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

After applying these I wondered if there are updates for PVE that would require a reboot (other than kernel). Is there a best practice regarding updates in the cluster for both PVE and Ceph?

PVE's services will be triggered and thus restarted upon a package-upgrade - so for this you won't need a reboot.
running guests will remain running with the old qemu/lxc version until you stop and start them again (a reboot inside the guest is not enough) - so if there's an update for pve-qemu-kvm or lxc-pve you might want to restart all guests (or reboot the node)

in general for linux-systems an upgrade of a library does not restart all services linking to that library - checkout the `needrestart` package - which "check which daemons need to be restarted after library upgrade"

hope this helps!
