We are very pleased to announce the general availability of Proxmox VE 5.4.

Built on Debian 9.8 (Stretch) and a specially modified Linux Kernel 4.15, this version of Proxmox VE introduces a new wizard for installing Ceph storage via the user interface, and brings enhanced flexibility with HA clustering, hibernation support for virtual machines, and support for Universal Second Factor (U2F) authentication.

The new features of Proxmox VE 5.4 focus on usability and simple management of the software-defined infrastructure as well as on security management.

Countless bugfixes and more smaller improvements are listed in the release notes.

btrfs does currently not perform in a way that we want to add it to Proxmox VE users. But you can use btrfs already, just confgure it manually.

No one here, or from the Community (AFAIK), is actively working on it, so postponed means here not real timeline, and if no one steps up it's unlikely for 6.0 I'd guess.
Some main issues are, fsync is _really_ slow, about an order of magnitude worse as ZFS (an FS with a similar feature set), this showed especially in our installer tests, as dpkg per default does an fsync after each file extracted (this could be work-arounded for the installer case, but stay an issue after installation..). RAID 5/6 is still unstable and replacing failed disks is not too ideal yet either. As soon as this is addressed, there probably will be more interest and motivation to support it officially, but until then we just see it not as ready to make it a "Proxmox VE first class FS" with more integration. I mean its included in the kernel so you can already try and use it as a basic underlying storage.

Do you plan to handle separate swap limit accounting using cgroupv2? LXC has cgroupv2 support since version 3.
Currently i can't use proxmox to configure LXC with swap limit smaller than total ram limit. Swap limit is now always "Memory+Swap"

It looks like it had already done the update. My load balancer had just connected me to a node in the cluster that the update had not yet been performed on.

some hints about vm hibernate? Specific version of qemu guest agent? I tried some minutes ago but it fails...

log display:

is strange because for that isci resource there isn't multipath...

qemu ping from command line works fine

If you find yourself with nonfunctional SSH after the update, please make sure you have libcomerr2 still installed

/usr/sbin/sshd: error while loading shared libraries: libcom_err.so.2: cannot open shared object file: No such file or directory

Had to reinstall it (apt install --reinstall) because after apt update, apt upgrade, apt dist-upgrade, my system still thought it has the newest version, but the lib was gone.

# apt-file search /lib/x86_64-linux-gnu/libcom_err.so.2
libcomerr2: /lib/x86_64-linux-gnu/libcom_err.so.2
libcomerr2: /lib/x86_64-linux-gnu/libcom_err.so.2.1

As openssh-server has a Depends on "libcomerr2" this really shouldn't happen.. We also did not changed anything on that, or the SSH package (which come from Debian Upstream)..

Can you check (and post) your /var/log/apt/history.log file to see what apt decided to do on the point of upgrading.

And remember, _never_ use apt(-get) upgrade, always dist-upgrade (or apt full-upgrade, which is an alias to dist-upgrade by the newer apt). Simply using "pveupgrade" saves remembering this too.

Commandline: apt dist-upgrade
Install: libpython3.5:amd64 (3.5.3-1+deb9u1, automatic), python3.5:amd64 (3.5.3-1+deb9u1, automatic), python3.5-minimal:amd64 (3.5.3-1+deb9u1, automatic), python3.5-dev:a
md64 (3.5.3-1+deb9u1, automatic), libpython3.5-dev:amd64 (3.5.3-1+deb9u1, automatic), libpython3.5-stdlib:amd64 (3.5.3-1+deb9u1, automatic), libpython3.5-minimal:amd64 (3
.5.3-1+deb9u1, automatic), libegl1-glvnd-nvidia:amd64 (390.87-8~deb9u1, automatic)
Downgrade: libmpc3:amd64 (1.1.0-1, 1.0.3-1+b2), debconf:amd64 (1.5.71, 1.5.61), lib32ubsan0:amd64 (7.4.0-6, 6.3.0-18+deb9u1), libmpx2:amd64 (8.3.0-2, 6.3.0-18+deb9u1), python3-dev:amd64 (3.7.2-1, 3.5.3-1), libcomerr2:amd64 (1.44.5-1, 1.43.4-2),....

So dist-upgrade did downgrade a lot of things, among others libcomerr2

I made sure /usr/sbin/sshd is the file provided by openssh-server
