  1. ZFS and special device how to use unused free space ?

    I know this might be a stupid question, but it also my be a good question. I've done a mistake and setup a special device with 700+ GB in mirrored mode, the mistake being too much space dedicated for this. I have already a separate partition from this for SLOG, but that's unrelated to the...
  2. Auto IPV6 via dhcp ?

    Hello, Has anyone succeeded in offering auto IPV6 from a range via dhcp to vm's ? I`m looking more specifically for using the IPV6 range that OVH offers. Any information is appreciated.
  3. ZFS Tests and Optimization - ZIL/SLOG, L2ARC, Special Device

    Since there are many members here that have quite some experience and knowledge with ZFS, not the only that I`m trying to find the best/optimal setup for my ZFS setup; but also want to have some tests and information in 1 place rather than scattered around in different threads, posts and...
  4. Proxmoz 5.4 from ISO missing ZFS conf ?

    Hello, I installed 5.4 from iso, and I cannot find /etc/modprobe.d/zfs.conf to be able to limit the ARC. Am I missing something ? Thanks
  5. Proxmox 6.1 with ZFS - High IO and Server Crash

    I cannot get my head around this, as I`m experiencing some very weird server IO delay and server crash. It seems I have this exact same issue [1][2]. The setup has ZFS + ZIL + L2ARC, however the RAM was getting used up to 100+ GB and the L2ARC was (and is set) to 150GB/read/write on the SSD...
  6. AMD EPYC - Has NUMA ?

    Hello, I`m very confused with NUMA, as I read from docs you have a NUMA capable host if you have multiple CPUs (sockets). However I have installed Proxmox 6.1 (latest) on a AMD EPYC 16 core CPU, and the command to check available numa returns: available: 4 nodes (0-3) node 0 cpus: 0 1 2 3 16...
  7. Recommended Read/Write/Ops settings for normal HDD ?

    Hello, I am having a hard time figuring out the best average values to limit read/write/ops for a "normal" HDD like HGST_HUS726020ALA610. I got 2x2 TB of these in SoftRaid, and machines running only Windows server. Because these machines have SQL on them sometimes a machine can read/write so...
  8. Proxmox 5.3.8 - IO delay issues explained ?

  9. 500 Can't clone to non-shared storage 'local'

    Hello, I have been struggling with the new cluster I setup using Proxmox 5.2. I have my KVM Templates .conf on the "main" node, and the disks on a NFS shared storage, so I can full clone them on any node. Well I can't aparently, because I always get: "Can't clone to non-shared storage 'local'...
  10. Proxmox 5.2 fresh cluster - KVM Templates storage ?

    Hello, Proxmox 5.2 is amazing, period. However I am in a loop hole as I do not understand the following issues: I could only mount 1 NFS storage instead of 1 x each nodes, I guess this is the way to do it inside a cluster ?! I cannot copy the KVM templates on all nodes, they always stay on...
  11. New cluster using Proxmox 5

    Hello, First of all I must say that the latest Proxmox 5 GUI is amazing, top notch. I just setup a new cluster using 3 servers, and I have a weird problem. The moment I enable the Firewall on the "Datacenter" level, the other 2 clusters show as offline. I tried allowing LAN/WAN IP's on the...
  12. Clock on VM using Proxmox 5

    Is there a way to stop the VM clock from changing it's timezone to the host timezone ? I really had no such issues with Proxmox 4, but it seems for some reason I have this on Proxmox 5. Basically the node has 1 timezone and the VM needs to have it's own timezone inside Windows OS, but it...
  13. Windows Server 2012 R2 on Proxmox 5.1-36 freezing without reason

    Hello, After I used out all my options, I feel like you guys are the only ones that can advise me or point me to the problem. Basically I have a node running Proxmox 5.1-36 and a running VM with Windows Server 2012 R2 link cloned from a template that I freshly prepared. Node specs: Intel...
  14. Proxmox 4.4 question regarding SSD storage

    I have a question, and if it's a dumb one please don't judge me because I am fairly new to Proxmox and starting to get accommodated... I have a dedicated server with 2 x SSD drives with Soft Raid, but I am able to use only one in Proxmox, and that doesn't seem right to me. I don't quite...
  15. SSD for VM really slow

    Hello, I have a dedicated server with SSD Soft Raid, and I created a few Windows templates. All went very well until I cloned my first VM from a template, the performance was horrible, so bad that you had to wait to open task manager... I after a lot of testing, I noticed that if I use "Linked...
  16. Critical security bug in NoVNC console

    Today, I was editing a product in WHMCS, and by "mistake" I saved the order with the "Server:" selected as another node, that it should really be. What happened after was horrible, because the user opened his console, and the was connected to another VM on another NODE, seeing the whole...
  17. Proxmox VE 4.4 100% SWAP Usage suddenly

    Hello, I really need some information/guidance why my Swap usage is suddenly 100% on one node and on the other one is 60% as well, suddenly... Each node has the same set of 128 GB RAM, and running only Windows VM's. Can someone please explain this to me ? Do I need to increase the swap...
  18. What is the qemu-nbd maximum limit?

    I'm trying to find out if I can add more than 16 nbd devices, because I would need at least 20, is this possible ? I tried more than 16 but it did not work, only 16 devices show ... The way I added now is: modprobe nbd max_part=16 echo "nbd" >> /etc/modules cat > /etc/modprobe.d/nbd.conf...
  19. Error: database disk image is malformed

    Following up my previous thread ( which has no solution at the moment ), I started searching what actually failed in my attempt to create clustering with running virtual machines. Commands run adn output: root@xxxxx:~# sqlite3 /var/lib/pve-cluster/config.db SQLite version 3.8.7.1 2014-10-29...

    I am facing a hard dilemma here. I am running Proxmox 4.x with vm's on it, and it's reaching the resource limits, so I want to setup clustering. I have setup another server with the same Proxmox 4.x ( but no vm's, just empty ) and I would like to add it to my primary one that is currently...
