    performance problems

    Hello, I have a strange problem in one of our servers that I think is related to the ZFS volume. If I run a du or ncdu command on this server to read the files, it is extremely slow. Takes about 30/40 minutes per TB. I don't notice the problem with writing to it. Before making the backup, our...

    Can't wipe drive & ZFS(8,4,4 fails to be created)

    I tried to format 3 drives (4TB, 4TB, 8TB) into a ZFS Array. This did not work. I then tried to format 3 drives into the other array types. This did not work. I proceed to format only 1 drive into a raid0 default drive. This did work. Now I want to wipe this empty drive. I then try wiping it...

    ZFS Raid showing incorrect usage?

    I have a ZFS Raid volume on each of my hosts and when I look at the Node's ZFS Window I see the correct utilization. To be clear, each host has 12 drives, configured in a raid 10 using ZFS. I named them the same due to what I saw was a requirement for replication to function in a cluster...

    pfsense VM with UFS leads to overfull vm disk until reboot

    Hello, I recently moved to running pfsense in a VM on pve-manager/8.1.4/ec5affc9e41f1d79 (running kernel: 6.5.11-8-pve). My proxmox storage is zfs, so using virtio block storage for the vm creates a zvol. In pfsense, in order to avoid zfs on zfs, and write amplification, I am using UFS as the...

    RaidZ1 performance ZFS on host vs VM

    Hi, I am currently testing my RaidZ1 setup. The plan was actually to create the ZFS pool (4x1TB PCIe NVME SSD) with Proxmox and then pass it as a disk to a VM, among others. In my benchmarks with fio, however, I noticed that the performance on the host was significantly higher (approx. 50%)...

    Feature request: Don't delete volumes onm restore which were excluded from backup

    On my old proxmox instance i didn't use zfs but the directory storage (.vmdk / .qcow2 files). I used VMs on which i excluded drives from backup. When i restored a VM, the disk was then marked as unused but still available to remount on that VM (after doing a qm rescan). I also had trouble with...

    Forming a 10Tb WD Ultrastar DC HC330 hard drive (part: 0B42266 and 0B42305) in Proxmox does not work, but ,in Windows10 formatting works.

    I can't format my hard drive in proxmox. It gives an error (file attached below). The latest current version of the proxmox update has been installed. But when running in Windows 10 through the disk management partition, formatting in ntfs format works correctly. Files on the disk run without...

    ZFS Installation: Storage Discrepancies and Overwriting Concerns

    Hi, Installed Proxmox with ZFS, choosing ZFS (RAID0) during installation with only 1 disk. I have two storage locations, local and local-zfs, both showing 2TB. Changes in one don't impact the used space of the other. For instance, downloading an ISO to local increases it by 3G, but local-zfs...

    ZFS over iSCSI

    Hi, Could someone please guide/refer me to a document detailing steps to configure ZFS over iSCSI using TrueNAS. If TrueNAS is not possible, then steps for ZFS (supported) on Linux. This is for the latest Proxmox and TrueNAS/Linux OS's. Thank you. I appreciate it. I have been googling to no avail.
