    As far as I know, on windows this is a "domain policy" pushed by the Active Directory. The windows domain policies don't work on anything but windows. Technically you can change the policy (GPT editor) to change the NTP server to something other...

    When synchronized with NTP, the RTC is typically not referenced. For example, in Windows, it is referenced at startup. Once synchronization with NTP begins, the RTC is never referenced again. If synchronization with NTP has not started, it...

    I don't know VMware but for Linux VM you can use ptp_kvm as the clock source: https://forum.proxmox.com/threads/how-to-enable-continuous-time-sync-between-qemu-guest-and-host.173396/#post-806460

    Not sure if it is 'The' recommended way, but as I mentioned, we rely on a NTP source in our network so it is reachable for all machines. In your case if you do not have the means to set up a dedicated NTP source, using one of the PVE hosts, or...

    This is not an 'ntp' option, this is for the startup of the vm, windows likes to have the system date/time in the local time zone, while *nix OS likes to have the system date/time in UTC. This option translates the host time for the vms to the...

    in our env we run chrony on all linux vpms using ptp_kvm and that works very well. For windows we currently just sync with the NTP server in our network, which is also used by the pve hosts. The reason for using ptp_kvm is that is has less...

    New information. had 2 reboots of hosts this weekend, same host both times, what is weird from the 2nd reboot, we have a very clear "OOM" problem. however our host at the moment has 3x the amount of memory provisioned all vm's combined are...

    For my side, had another reboot this friday, 2 PVE hosts. We traced the issue to our ceph HDD pool which is being slow at that moment. Were moving some copy/sync which is going to the HDD pool to be more stretched out and not all hosts hitting it...

    The current version of pve-ha-manager is 5.1.0 which does not contain any of these patches. Also there is no 'testing' version available yet, the patches seem a bit much to all do manual, do we have any timeline when a 5.1.1 would come in testing?

    it seems, but it is absolutely not, our normal cpu load during the day is kept very low, same with memory. This 'overloaded' is caused purely by io delay on the mounted backup volume, which makes sense is slower during backup windows. This should...

    Good to know this affects everyone equally :-) We have had discussion on this topic in the past on this forum, It would be nice to get a way to see the softdog status and get logging of when the watchers decide to NOT ping the watchdog for...

    We have had this same issue since replacing our intel based nodes with amd ones. Lately we have unexpected reboots at least weekly on one or more nodes. For us this always happens during the backup window (lucky?) and we see high IO delay right...
