    Integrating PMG and Setting up Certificates & DNS Records

    DMARC etc need to point to server, which is sending the mail, so mailservers. There is no cost to having PMG in those records too anyway. For certificates, the right way is such that works in long run.

    Extremely SLOW Ceph Storage from over 60% usage ???

    You cant't evade not using swap when swap is present. You can set swappiness parameter, remove swap, raise RAM, or more debug the problem.

    MTU-size, CEPH and public network

    You can do tests. From my point of view mixing 1500/9k mtu on same interface is calling for problems. I tried something as this before even ceph was in pve and it was mess. Network latency will have higher performance impact than 9k mtu.

    Is it possible for HA to simply monitor a network link ?

    Not from PVE side. You need implement something as STONITH (locally or remotely), for example shutdown the affected node.

    Upgrade 6.2 to 6.4 - high disk utilization in VMs

    Previous image is zabbix standard disk template. Even netdata shows something crazy for VM system disk: And VM db data disk: Both disks are on this PVE host, dedicated raid for VM images: PVE OS raid diskset: All VMs are Debian 10. Upgrade was done only on PVE host level.
