  1. HA starts VM after proper shutdown

    Hi all, i have a 3 node cluster. In my HA section i created a group with all nodes and i added my VMs as resources (in this case VMID 200). If i shutdown the VMID 200 from console/ssh (using "shutdown -h now" or "poweroff") or using "shutdown" from PVE GUI, the VM goes down but after a second HA...
  2. how to know how many vCPU i can use for creating VMs?

    Hi, I am reading some article that says, to calculate vCPU is using this formula: (Threads x Cores) x Socket = vCPU I am curious, is that formula is right? Let's say i have a physical server with 1 CPU @ 4 Cores/8 Threads and 32GB RAM with Proxmox VE running inside and with that formula, that...
  3. Proxmox unlinked my VM's disk, and now it does not show up in the VM's storage

    Hello everyone, I am having some trouble right now, and I'm unsure how to solve it. My VM was running like normal, and after a while (probably after proxmox restarted) it disconnected one of the drives for that VM without allowing me to reconnect it. But it still shows up in the storage area of...
  4. Upgrade problem

    Hi, I have a Proxmox cluster with 4 nodes in it. When i want to upgrade one of my node, I dispatch my VMs of the node that I want to upgrade through the other node. Then I upgrade my node and I restart it, and when I restart it the VMs that are in the other node restarts for no reason. So i...
  5. [SOLVED] backup failed for non-existing VM

    Hello Proxmox, I deleted 2 VMs from our cluster (that had backup jobs on them). Subsequent backup jobs fail on those VMs with "no log available", even though those VMs are not listed in the backup job. I'm getting an email from every single host in my cluster. How can I remove those VMs IDs...

  7. Best to store VMs/CTs in zpool or in separate datasets?

    I have a single NVMe drive for Proxmox to boot from. I'm going to add 2x SATA enterprise SSDs to my host, create a ZFS mirror, then move my VMs/CTs to that mirror. Is there any benefit from having separate datasets for VMs and CTs (like below), or should I put everything on the pool itself...

  10. I dissolved the cluster and my ZFS was unmounted, now I don't see the VM's

    Hi, I hate being new to a forum and starting with a question. But when he dissolved the cluster, the ZFS was unmounted, I remounted it from the Datacenter, but I can't find how to load the "disks" in new VMs or, if possible, in the old ones. My last backup is not a good option because it is...

    Kann ich irgendwie in Proxmox festlegen das auf einem Host nur maximal bspw. 30 VMs/LXCs laufen dürfen? Muss nämlich bei einem Cluster dafür sorgen das nicht zu viele VMs auf einem Host gestartet werden können.
  12. VM storage on ZFS pool vs ZFS dataset

    Hi, I'm planing the installation of a new proxmox instance, and I'm thinking about the storage model to follow. In my case, I will have a 2x Samsung SSD 860 PRO 250Gb disks on mirror mode for proxmox boot, then I'll create a ZFS pool of mirrors (raid10) for storing data. My initial idea was...

  15. Problem trying to recover VM

  16. [SOLVED] One GPU multiple VMs acceleration and Plex encoding

    I have dell r720 that I'm running proxmox on. I'd like to buy one big graphics card to be able to run my windows 10 pro vm and ubuntu 20.04 with some machine learning tasks off one gpu. I was looking at buying something like a rtx a5000 or rtx a6000 to accomplish running both and using a little...

  18. Best way to store VM's on zfs - on the pool or in datasets?

    Hi On my PVE host, I have a 2-disk SSD mirrored zfs pool dedicated to VM's, CT's, ISO's, etc. called pvestorage. Now I'm trying too figure out whether to store my VM's directly on the zpool or in subsequent datasets like pvestorage/vms/vm1 ,/vm2, etc. So I've tried to read up on the topic on...
  19. Snapshots naming scheme

    Hello, We have a backup schedule for PBS that run at 23:00 EST everyday. The issue we have is that the naming scheme for the snapshot seems to be built using a different timezone. An exemple would be if we backup a VM the 21 of May at 23:00 EST, the snapshot name would be 22 of May 3:00 This...
