We're excited to announce the final release of our Proxmox VE 6.0! It's based on the great Debian 10 codename "Buster" and the latest 5.0 Linux kernel, QEMU 4.0, LXC 3.1.0, ZFS 0.8.1, Ceph 14.2, Corosync 3.0, and more.

This major release includes the latest Ceph Nautilus feautures and an improved Ceph management dashboard. We have updated the cluster communication stack to Corosync 3 using Kronosnet, and have a new selection widget for the network making it simple to select the correct link address in the cluster creation wizard.

With ZFS 0.8.1 we have included TRIM support for SSDs and also support for native encryption with comfortable key-handling.

The new installer supports ZFS root via UEFI, for example you can boot a ZFS mirror on NVMe SSDs (using systemd-boot instead of grub).

And as always we have included countless bugfixes and improvements on a lot of places; see the release notes for all details.

FAQ
Q: Can I dist-upgrade Proxmox VE 5.4 to 6.0 with apt?

A: Please follow the upgrade instructions exactly, as there is a major version bump of corosync (2.x to 3.x)
https://pve.proxmox.com/wiki/Upgrade_from_5.x_to_6.0

Q: Can I install Proxmox VE 6.0 on top of Debian Buster?
A: Yes, see https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Buster

Q: Can I upgrade my Proxmox VE 5.4 cluster with Ceph Luminous to 6.0 with Ceph Nautilus?
A: This is a two step process. First, you have to upgrade Proxmox VE from 5.4 to 6.0, and afterwards upgrade Ceph from Luminous to Nautilus. There are a lot of improvements and changes, please follow exactly the upgrade documentation.

That was fast! so soon after the beta was released, Nice!

Changing over from beta to release was as easy as editing 1 apt line and apt update/upgrade :)

It should start by default. Check if the pveproxy service is running.

Apologies. It works on htps:// <host-ip> :8006. I would be more specific in the message given just before approving reboot.
There's also the "issue" message visible after boot to make this a bit more clear, for example:
Welcome to the Proxmox Virtual Environment. Please use your web browser to
configure this server - connect to:

https://192.168.16.38:8006/
But I guess clarifying it an additional time on successful installation does not hurts.

I guess so. It happened to me because I have the console on one PC on one lan and the management interface running on another pc on another lan.

The thing is that the message given on successful completion of the installation is misleading (something like, after reboot connect with your browser to the management interface)... without mentioning the port 8006.... that's all. Just a small thing.

No worries, makes sense to have, I've a patch ready which would results in: installer-success.png
For this release to late, but maybe for the next one :)

For users upgrading from PVE 6.0 Beta to PVE 6.0 using a redundant ZFS rpool:

the mechanism used to synchronize the EFI System Partitions ("ESP") storing the actual kernels and initrds which are available for booting has changed from the Beta ISO to the final ISO.

If your system is using ZFS for the root file system and has been setup with the PVE 6.0 Beta ISO, please check the output of "pve-efiboot-tool refresh". If it prints the following error message:

Code:
# pve-efiboot-tool refresh
Running hook script 'pve-auto-removal'..
Running hook script 'zz-pve-efiboot'..
Re-executing '/etc/kernel/postinst.d/zz-pve-efiboot' in new private mount namespace..
No /etc/kernel/pve-efiboot-uuids found, skipping ESP sync.
You need to initialize each ESP with pve-efiboot-tool. To verify which partitions contain an ESP, use "lsblk" on each disk making up your rpool (replace '/dev/sd?' with appropriate paths if your devices are named differently):
Code:
# lsblk -o path,parttype,fstype /dev/sd?
PATH      PARTTYPE                             FSTYPE

vfat partitions with partition type "c12a7328-f81f-11d2-ba4b-00a0c93ec93b" and index 2 are ESPs setup by the installer. For each of those partitions (e.g., /dev/sda2, /dev/sdb2, /dev/sd2), use the following command to re-initialize the ESP and register it for ongoing synchronization:

All done, i needed to change this (but an earlier reboot went fine thou)

Mind you that for an nvme drive this command obviously changes to something like:
Code:
lsblk -o path,parttype,fstype /dev/nvme0n?

this means your hostname and local network setting are in disagreement. your hostname should resolve to one of your local IP addresses. either you have an old/outdated/wrong IP in /etc/hosts, or your DNS responds for your hostname with wrong information.

Just upgraded my server running 5.4, ZFS and a four disk setup with two striped mirrors, booting from the first mirror.
Hardware is a HP Microserver Gen8 with disk controller in AHCI SATA mode.
So for, every 5.4 kernel update had worked and the system would be able to reboot.

Now, after upgrading to 6.0 and reboot, the system crashes with

Code:
Attempting Boot From Hard Drive (C:)
error: no such device: (uuid)
error: unknow filesystem.
Entering rescue mode...
grub rescue>
I know this was mentioned in another thread, but this is the first time it happens and must be related to the upgrade to PVE 6.0.
Enclosed is the protocol of the upgrade...

Any idea of what might have gone wrong?
