Thank you for the explanation. I think it would be better to host an PBS on site and use the remote sync feature for offsite Backup.

Hi, I have a strange issue with the Proxmox Backup function. I have 4 Clusters (2+1) running with DRBD as storage backend. On a other location (in a data center) runs a Proxmox Backup server. Both locations are connected via 1GBit/s. Now I want to backup all of my VMs to the PBS over the 1GBit...

Same here. Upgrade qemu-server to 9.0.29 fixes the problem.

Hi, i have a 2+1 node (2 nodes + 1 qdevice) cluster with linstor drbd as shared storage. One node is running on version 8.4.14, the other one on version 9.0.15 (freshly updated). When i now live migrate all vms to the newer node (to upgrade the node with version 8) the migration fails for vms...

Yes I am using KRBD for this pool. There is no LVM on top of it, so the VMs are using the rbd images as raw device. The load of the machines in the cluster is currently really low. The Cluster is new and there are just a few VMs running on it. There is under 5% CPU load on all nodes. All 5...

Yes compression is enabled on the pool with following settings: compression_mode: aggressive compression_algorithm: lz4

I was able to limit the problem to an Windows VM running Server 2016. Currently it is the only Windows Server 2016 guest on the Cluster. When i migrate the VM to a other node the error messages stop appearing on the source node and a few minutes after migration they start appearing on the node...

@gurubert can you please explain how the MTU size does affect this behavior? I am running an 5 node Cluster with a similar problem. Currently the network interfaces for ceph communication are set to mtu 9000.

Hi, I'am testing around some cluster failure scenarios. I have an 2+1 Cluster (2 nodes + 1 qdevice). Suppose node 2 and the qdevice are unrecoverable and both need to be newly installed. The problem is that i need to remove the qdevice before i can add the newly installed node 2. When I try to...

Hi, i still testing around with some cluster failure scenarios. It seems that it is not possible to login on the webgui when 2 of 3 Clusternodes are down. When i try to login with any account on the last operating node i get the error: "Login failed. Please try again" User, Password and Realm...

Was sagen die Befehle: dmesg |grep e1000e ethtool enp0s31f6 ethtool muss eventuell erst per apt installiert werden Das Kabel wurde schon testweise getauscht? Ich geh davon aus, dass sich auf der anderen Seite der Verbindung ein Switch befindet? Sollte dieser über eine CLI verfügen kann man da...

Hallo, ein kleines bisschen mehr Info sollte es schon sein. Ist es ein einzelner Port oder ein Bond? Ist der Linkspeed wirklich auf 100Mbit/s gesetzt, oder "fühlt" es sich nur wie 100Mbit/s an? Wenn möglich zieh mal das Netzwerkkabel bzw deaktivier den Port, danach wieder Kabel rein oder Port...

Hi I have an strange behavior when I resize the blockdevice of an vm. As an example I have a vm with an blockdevice which is 10GiB in size. In the webgui and the vm cfg file the size is shown correctly. Now when I resize this blockdevice by 1GiB in the Webgui, the new size is shown as 11536152K...

Hallo zusammen, werden die im Proxmox hinterlegten LDAP bzw AD Server periodisch gesynct? Oder findet lediglich ein Sync statt wenn man ihn manuell anstösst? Leider habe ich sowohl in der Doku als auch in den Logfiles nichts dazu finden können. VG Paul

Hello @all currently I am setting up a 2+1 node (2nodes + 1 qdevice) Proxmox Cluster with Linstor DRBD as shared storage. As described by Linbit I added a VM as Linstor controller to achive ha for the Cluster. In case of an failure of the Cluster node where the VM is running Proxmox-HA tries to...
