  2. Does Proxmox need fast storage?

    Hi, I have a simple question which I would like to share with because I’m interested in you point of view. On a Proxmox server I have fast storage (SSDs or NVMe) and slow storage (SAS or SATA). My fast choice could be to install Proxmox on fast storage and use it also for storing virtual...

    Add SSD to RAID-10 ZFS?

    Hello! we have 2 servers with local ZFS pools. The pools are configured with the same type of disks. They have 3 x 120GB SSD and 4 x 4TB HDD. I set the 3 SSD as a physical RAID 5, there runs Proxmox on one partition and ZFS logs and cache on 2 other partitions. Then, with the 4 HDD I set up a...

  11. Intel NUC single SSD - best filesystem?

    We're planning on using a few Intel NUCs in lab conditions with Proxmox. They take a single M.2 NVME device. What would be the best filesystem to use in this case? Also if ZFS would a RAID1 or RAID0 array be the correct option?
  12. Super slow performance on Proxmox SSD

    We're evaluating Proxmox in our lab and have two setups - both running 5.3: 1. Xeon Storage: ZFS (10x 3TB SAS + 100GB ZIL SSD) 2. i7-7700K Storage: ext4 LVM (1x 1TB SATA SSD) Running the following sysbench commands inside identical LXCs to evaluate storage performance: sysbench...

    Hallo zusammen, ich teste gerade eine Konfiguration mit Proxmox VE 5.3-8 und habe ein Problen mit zwei NVME SSDs. Die Grundinstallation hängt an zwei SATA SSD Platten auf denen ich zuerst die virtuellen Maschinen getestet habe. Hierbei gibt es auch keine Probleme - jetzt wollte ich noch zwei...
  15. ZFS Raid1 (2x 'cheapo' SSD) - additional single drive for backups?

    Hi there. I'm doing some maintenance on a desktop based 'server' used as SQL database host for ca 5 LAN users. It was running bios-software RAID1 on 2x Samsung EVO 250GB SATA SSD's. I know that those are NOT server grade but what can you do :/ 3rd drive is a regular 3,5" 1TB SATA for backups...
  16. Basic IO benchmarks between zfs/lvm-thin/qcow2

    Just ran these the other week, thought I'd share. I'll try to do some more proper ones on Linux, but before that happens here's some CrystalDiskMark ones on Windows 2019 (virtio-scsi). The underlying storage is a single Samsung 850 PRO SSD. I was pleasantly surprised by the QCOW2 performance...
  17. Support External RBD And CephFS with Erasure Coded Data Pool

    We want to run backup of CephFS with erasure coded backed pool at k=10 m=2, but we couldn't get this to mount on our proxmox ve 5.3 Also, being able to create EC RBD pools would be great where we are running with k=2 m=1, which has faster reads at low disk cost than replica=3
  18. VMs auf einfache SSD auslagern

    Hallo zusammen, ich wollte mir demnächst einen neuen Proxmox Server auf AMD Ryzen bauen. Bis dahin wollte ich aber meinen jetzigen mit einer SSD ausstatten - aktuell PVE + VMs nur auf einer WD Red 2TB, reicht für meine Basteleien aus, wollte aber mal um zu sehen wie es mit der Performance...
  19. High ZFS disk usage in Proxmox

    Hello I have installed Proxmox VE on a group of SSD disks raid-0. My problem is that while copying a file to a VM, then deleting it, it won't reclaim disk space on local-zfs. However, while running "df -h" in VM command line, it shows amount of space less than real space in local-zfs.
  20. [SOLVED] ZFS Raid 10 with 4 SSD and cache...SLOW.

    I had a Raid 10 ZFS pool over 4 HDD with a SSD cache, and I thought "I wish I had known about ZFS sooner". So I put together a Raid 10 ZFS pool over 4 SSD (and later added a SSD cache), and am thinking to myself, what did I miss? I have compression on. These numbers are worse than the...
