Hello!

Following the wifi on: https://pve.proxmox.com/wiki/Upgrade_from_5.x_to_6.0

I got error on this step:
For the no-subscription repository see Package Repositories. It can be something like:

sed -i -e 's/stretch/buster/g' /etc/apt/sources.list.d/pve-install-repo.list

I got this error:
sed: can't read /etc/apt/sources.list.d/pve-install-repo.list: No such file or directory

Any idea to fix that?

And, im not using Ceph, but anyways, i need to execute this step?
(Ceph only) Replace ceph.com repositories with proxmox.com ceph repositories

Hi Lucas,
the trick is "can be something like"... mean, you have source lists, which uses oldstable stretch, wich must replaced by buster.

to find your files use

Code:

grep -r stretch /etc/apt/

sed is an streamline-editor and the command simply replace stretch with buster in the file (like vi command s for substitute and g for global (all)).

Ok, but my 5.4 is already with buster, so, i cant understand why i need to replace that again, my sources.list:

deb http://ftp.br.debian.org/debian buster main contrib

# security updates
deb http://security.debian.org buster/updates main contrib

There is no 5.4 with Debian Buster, as PVE 5.x is based on Debian Stretch.

Hello everyone !!
yesterday I did the upgrade from 5.4 to 6, no errors during the process.
But after the reboot i got :

Code:

root@pve:~# systemctl status zfs-mount.service
● zfs-mount.service - Mount ZFS filesystems
   Loaded: loaded (/lib/systemd/system/zfs-mount.service; enabled; vendor preset: enabled)

I had a bit of a further look :

Code:

zfs-pool/vm-disks/vm-335-state-preupdate  -                                  -

Did Proxmox manage to write to the mount points before zfs was active ??
How do I recover from this ?

EDIT : this looks like a solution.

When ZFS storage is configured as directory storage, then this solution should help.

Clean new installation with subscription keys!!

Each Server of our cluster has a Proxmox VE Community Subscription 1 CPU/year!!

We 'checked' the subscription --> all ok!!

Whats up - sometimes ok sometimes not -??

The short story:
In proxmox 6 fallocate: fallocate failed: Operation not supported

The long story:
Sometimes I can't start my virtual machine because Proxmox says that there is not enough memory space (and it is very strange because I have a server with 16GB of RAM and my KVM is configured to use only 8GB) .

I installed Proxmox v6 in raid-0 zfs and noticed that no swap file was created (and it is very very strange!).

I thought of creating one in the hope of solving the problem but I encountered another error: it is not possible to use the "fallocate" command.

To reproduce the problem of not starting the KVM it is sufficient to do so:

launch Proxmox;
make a copy from one server to another with the "scp" command of a backup file of the kvm of at least 10 GB file;
restore the kvm on the server in use;
start the kvm and you'll meet the error;

Best regards,
E. Bruno.

.

Could be memory fragmentation. KVM needs a contiguous piece of memory. If it's fragmented then you'll need to defrag.

You could try "sysctl vm.compact_memory=1".

zfs will use half of memory by default for his buffer cache. (and linux kernel can't retreive it like classic linux buffer memory)

until someone more knowledgable answers : that particular file is not of much importance for your install, i believe it is responsible for displaying the welcome message on the console after reboot (smt like : you can now connect to the webinterface at https://192.168.0.1:8006 ).
Fine to keep the existing file.

Unable to install proxmox ve6.0
When I installed proxmox6.0 on the Huawei RH2288V3 server, I always stayed on the "END USER LICENSE AGREEMENT (EULA)" interface. I could not click the "i agree" button, and the installation could not be continued. I have collected some error messages. What should I do?
But test version 5.4, can install it normally!

Proxmox VE 6.0 released!
