    Windows Guest memory utilization problem on PVE 9.0.x

    If that is all you get, then no, it is not working as expected. Is the Balloon Device enabled in the VMs -> Hardware -> Memory settings? Is the "Balloon Service" running in the Windows guest? Is there no device without a driver in the device manager? One reason why you see a lower memory usage...

    ZFS Pool full even though VM limited to 50% of the pools size

    Hmm, how did you create that ZFS pool? Which version of PVE? I tried to recreate that in a test VM and even after writing almost 10G into a 10G volume, I get the following result: root@pvezfstest:~# zfs get all vms/vm-100-disk-0 NAME PROPERTY VALUE...

    Windows Guest memory utilization problem on PVE 9.0.x

    Why don't you stick with the last possible virtio version for 2008 SP2? Which one that is, I don't know right away.

    ZFS Pool full even though VM limited to 50% of the pools size

    Hmm, so the pool setup is a simple as possible: single disk. That means no additional overhead for parity. Only 1 copy and no snapshots, but still used and written twice as much as logically used. The used / written is almost double that of the volblocksize / refreservation, which, without...

    ZFS Pool full even though VM limited to 50% of the pools size

    I don't see any mention of how the pool is built. Can you post the output of zpool status? If it is a RAIDZ pool, this might not be too surprising. Background: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysadmin_zfs_raid_considerations Though with larger volblocksizes, this should be...

    Mixed PVE8/PVE9 cluster - how stable is it?

    What @apoyen said is correct. In general, also within the same major version, the following applies to live migrations: old → new version should always work. new → old can work, but there might be breaking changes. During an upgrade, you might run into errors if you use the web UI of one node...

    [SOLVED] kaputtes CEPH nach Upgrade auf PROXMOX 9.1.2

    wirklich? Ist das no-subscription repo aktiv? denn dann wäre es auch trotz der Fehlermeldung nicht so tragisch, da die Pakete dann übers no-subscription kommen können

    [SOLVED] kaputtes CEPH nach Upgrade auf PROXMOX 9.1.2

    Das klingt alles ein wenig seltsam. Ist evtl ein Repository auf die falsche Version konfiguriert? Kannst du mal apt update laufen lassen und den gesamten Output posten?

    Snapshot as volume chain for file level storage, use cases?

    AFAIK, snapshots as volume chains can be useful on the file system level because reverting to/deleting a snapshot in a QCOW2 image needs to halt the IO to the image at some point for more or less time. That is avoided if you use snapshot volume chains. I haven't touched that part in detail, so...

    [SOLVED] Seit Upgrade von Proxmox VE 8.4... auf 9.1.2: Höhere CPU‑Last bei Backups und allgemein höhere Serverlast

    Ich glaube, das ist, was @meyergru erwähnt. Mit PVE 9 haben wir die Zeitabstände, über welche die Messdaten aggregiert werden, kürzer gesetzt. Wie in den Release Notes erwähnt https://pve.proxmox.com/wiki/Roadmap#Proxmox_VE_9.0 Wenn man deinen ersten Screenshot ansieht, sieht man auch gut, wie...

    KRBD 0 Ceph prevents VMs from starting

    As a first guess, I don't think you should add the ports here. Can you try it with just the IPs in the storage config? And please use the code block formatting that usually makes reading output a lot nicer :)

    KRBD 0 Ceph prevents VMs from starting

    Is that the output from the task log? What output do you get if you try to start the VM from the CLI? qm start <VMID>

    vUSBPB - a virtual USB Power Button for Proxmox VM

    Ha, that sounds like a fun idea to make it all more physical/haptic. I haven't tested it, but have you seen changes in the USB port numbering on reboots? Also for example if a USB hub is used?

    Support clone/move rbd images including snapshots

    Hey, feature requests are best placed in our bugtracker https://bugzilla.proxmox.com. The forum makes it easy to lose track of them. We are having plans to make extend the storage plugins to make it possible to defer certain actions to the plugin. So that we do not use the generic approach via...

    Help to setup cluster

    No, only during a clean bare-metal installation you need to be careful.

    Help to setup cluster

    A node on which the cluster is initially created can have guests. Any node that is joining the cluster needs to be empty. Therefore create the cluster on the node with the PCI passthrough TrueNAS VM. The other node needs to be freed. Either by using a remote-live migration or backup->restore...

    Support Licenses

    To be even more pedantic, ;) the subscription, depending on the level, will give access to the enterprise repository. Which we definitely recommend for production environments. And then, depending on the level, can also include support tickets. The license of our products is primarily the...

    Mellanox ConnectX-4 LX not getting 10GbE speeds

    well according to this, it negotiated to 1Gbit: So it could also be a bad cable that caused the autonegotiation to scale back to the slower 1gbit. Keep an eye on how stable the connection is and how many retransmits you will see over time. ip --statistics a will show how many packets are...

    Mellanox ConnectX-4 LX not getting 10GbE speeds

    How do you test the speed? Which speeds did the NIC negotiate with the switch? ethtool <NIC> and look for the Speed: line.

    CEPH stretched cluster : PVE partition is not the same as the CEPH partition !

    I don't know right now. I would have to recreate the scenario and test it myself.
