It looks like this is changed with the cpupower tool:
Code:
cpupower frequency-set -g SCHEDULER

- Start date
AFAIK in Hetzner using iKVM/IPMI console is not free and fast available service, so I install all my nodes with Hetzner's Debian distro and then apt-get PVE from repositories (as Hetzner's HOWTO recommends). For now I can't install PVE on Hetzner's dedicated server because of Debian 11 is not released and available for installimage there, and I can't upgrade PVE 6 to 7 version also because I have all my VM/CTs backups in PBS co-installed with PVE and not supported by PVE7 now.
So, I'll wait until Debian 11 image got to Hetzner and/or PVE installation procedures got more elastic and mature, while playing with PVE7 in small local testing hosts. Or is any other good way to install PVE on ZFS to Hetzner's dedicated server?

Update from 6.4 to 7.x went fine, when asked from installer I used maintener version of files (about 4 times this occured during upgrading)..
Also, all VM are running fine (Linux, Windows, Containers).
The only problem which I can find is (marked with red color):
Should I do anything regarding these 2 services or is this normal behaive?
Also question... I got warning in Repositories section...
Should I delete line where is no "pve-no-subscription" or enable it?.. And regarding "buster" which is used in VM (I know that is old, but is working), should I try to update VM maschine also and delete this line?
Thank you for answers..

installing worked fine for me with:
- installimage, debian10.9 with mdadm raid, install pve6, upgrade to pve7, set hwaddress for main bridge, reboot, done
- rescue, install qemu, write down nic name and MAC of main NIC, download pve7 iso, start qemu VM with pve installer, install with ZFS or btrfs raid, reboot VM after setup (not Server), Login and correct NIC name and set hwaddress to vmbr0, shutdown VM, reboot server, done
Personally I prefer dedicated small DC ssds disks for the OS with mdadm and dedicated DC nvmes for storage with ZFS. fastes way to setup and maintain.

Hi,
chrony is the new default instead of systemd-timesyncd, but AFAIK if you want to switch, you need to manually set it up for existing setups. What does
systemctl status corosync.service show? Can you start the service? If not, please share the output of journalctl -b0 -u corosync.service.The no-subscription repository is disabled, so no problem. And If the InfluxDB
buster repository works, you can safely ignore that error too. But in general one should avoid mixing suites, so once the InfluxDB bullseye repository is available, you should switch to that.I'm currently testing some vm workload with spiky workload, and I notice latency increase too. I think we should indeed use performance by default, and maybe add an option somewhere to change it if user want it (maybe through pvestatd or another daemon)
Already switched back with latest kernel (will be available soon on public repos).
Hi,
on writing
systemctl status corosync.serviceI got:
The status on services is:
So the crony is installed ( I used instructions https://www.tecmint.com/install-chrony-in-centos-ubuntu-linux/), after that chrony is installed and running.
If I tried to run corosync nothing happens, status is allways dead. "systemd-timesyncd" is now also "disabled" - after chrony installation, assuming that this is OK.
If I run
journalctl -b0 -u corosync.serviceI got:
I am newby and do not know what this is meaning...
BR,

The corosync configuration file does not exist. But if your node is not part of a cluster, you can safely ignore this.
Yes, you don't want two time-syncing services running at the same time.
So, all is good... uff.. thank you
Can be "systemd-timesyncd" somehow deleted from service list?
Not really. It's part of the services our API checks the status of, so there will be an entry for it.So, all is good... uff.. thank you
Hello,
can i add Proxmox 7.0 node into 6.1-3 cluster ?
I want reinstall existing nodes, as i need to reformat their local storages (VMs are running on local storages with 10GBit network).
So the idea is to Join 6.1 Cluster with new installation of 7.0 node, live migrate all VMs onto it, then reinstall the 6.1-3 to 7.0 and migrate VMs back.
I have noticed that there are corosync 3.0.2-pve4 on 6.1 and corosync 3.1.2-pve2 on 7.0, will those packages cooperate
?

No. Proxmox VE needs to be updated to latest 6.4 before being able to upgrade/work with 7.0 for the update.
Upgrade to 6.4 first, then that could work.
Maybe, maybe not - nobody tested that here. We only test upgrading from latest 6.4 - you may have luck, but zero guarantees from our side.
Did a fresh install of "7" or a rack system connected to a Raritan VGA KVM, but once the system changes video mode to get to the login prompt, I got a "Invalid video mode" message on the KVM.
This used to work on Proxmox 6. Any additional configuration change I need?
Thanks!

That was only the first "lab" system (And yes, it was `ldd` I used to track that problem
), the 2nd/3rd cluster installation/upgrade had no netdataThank you for the info.
One more queston , please. Have you tested 6.4 together with 7.0 in one cluster ? corosync package is the same in 6.1 and 6.4 - 3.0.2-pve4
Just for clarity: you manage to install PVE 7.0 just fine, but afterwards, once you boot and get to the normal console login it breaks?
No it is not, if then you did not really upgrade to 6.4 ...
Latest PVE 6.4 versions are:
Code:
pveversion -v
proxmox-ve: 6.4-1 (running kernel: 5.4.124-1-pve)

Cluster 6.4 and 7.0 is possible, but only for migrating guests from old -> new for the upgrade, the other direction is not supported (may work offline, but not for live-migration!).
