  1. Configuration HBA SAS FlashSystem 5015

    hello gentlemen, I have an SR650 V2 server connected via 2x SAS/HBA cables to each node of an IBM FlashSystem 5015. I do all the storage configuration, making the volumes available to the host (SR650), but it is showing duplicate volumes: What configuration should I perform to recognize in...
  2. Moving Physical Disk (USB) & VMs to new Proxmox Node

    I've been using Proxmox nodes in a cluster of 2 for awhile and they both have relatively low resources, so I bought a PowerEdge R720 that's a lot more capable. At the moment I'm low on storage and I've been using an external 4TB HD external HD on one of my existing nodes. I'd like to be able...
  3. Mount external CephFS - no fsname in /etc/pve/storage.cfg

    Hi I'm trying to add external cephfs storage directly in /etc/pve/storage.cfg because I need to specify "subdir". (It is not possible to type subdir in the GUI) But I also have to specify 'FS name' because it's not the default cephfs file system. Can I add 'FS name' to etc/pve/storage.cfg and how?
  4. [SOLVED] Netzwerk nachträglich separieren

    Servus, jetzt hab ich wieder eine Frage ... Notgedrungen habe ich bisher mein kleines Drei-Node-Cluster plus pbs mit VMs, Storage und Corosync in ein und demselben Netzwerk betrieben. Die Latenz für Corosync ist ~1ms, also kein Problem, die Netzwerkauslastung hält sich in Grenzen. Dank einiger...
  5. [SOLVED] Random access speed slowdown in Nested Proxmox

    Hi. Please take a look at the image comparison first. I ran Crystaldiskmark on a bare metal Proxmox and a nested Proxmox. The storage random access speed is clearly lower on the nested. What could be the cause of this? I imagine it is the block size. Memory cache is set to "none". Any Idea?

  8. Variety of disk errors, can't delete VM "unable to open file" "Input/output error" & "Broken pipe"

    1.) I can't currently delete a VM which was created, setup, shut down and left off - it's not important at all. That file doesn't exist? I've rebooted so I'd expect any "locks" to files to be cleared? The VM was only used for a few hours shut down and left off. NOTE: this VM has never even...

  10. How do I create and add a secondary partition to my NVMe drive?

    I've installed Proxmox on a 1TB NVME drive, and used the advanced settings to tell the installer that I only wanted to use 256GB for Proxmox. Now I'd like to create an LVM-Thin partition on the remaining 750GB(ish) to be used for storing VM disk files. I can't seem to find out how to do this. I...
  11. [SOLVED] 7.4 cluster with mixed storage (XFS and ZFS)

    I have issues since on my Proxmox cluster since I added a new node with ZFS (RAIDZ2) storage. I had a 3-node cluster (version 7.3) where each nodes (names: node1, node2 and node3) had a single disk using XFS filesystem, I added a new v7.4 node (name: node4) having 8 disks ZFS RAIDZ2. Note...

Several community members...

    I am hoping someone might be able to explain or help me understand what might be happening with a couple of containers I have which use nfs mounts to my truenas server. On the truenas server I have three nfs shares: nfs1, nfs2 and nfs3 On proxmox I have two lxc containers: lxc1 and lxc2 I...
  14. Pass storage backed mount point to LXC container

    I'm trying to pass through an existing LV to a container. I believe this means I need to use an image based, storage backed mountpoint as described here, which mentions a special syntax for creating a new LV, but there is no mention of the option to mount an existing LV. I have created a new...
  15. For the Wishlist: Storage in GUI needs an R/W and IO Overview

    Hello Maybe something like that is planned or maybe not. In the Storage View of ZFS, LVM, ... you can see available Storage. But you can't see any Performance Stats of this particular Storage, like overall Read/Write Bandwidth or IO Bandwidth.. This would help to monitor Storage directly in...

  17. Optimal Storage Configuration for a Low-Power Server

    Hi Guys, Soon I want to build a Low-Power Server with one of those Erying Motherboards. Since I live in Germany and Energy is expensive here, I'm kind of compromised in the Storage Setup. This Setup is only used for an SMB Share that's connected via a 10Gig SFP+ Card. I will add a list at the...
  18. Priority Between Multiple Backup Storage Locations

    On my PVE I had 2 backup storage locations defined, pbs1 and pbs-offsite1 (which is a remote that syncs from pbs1). The reason for this configurations is for the case where the primary backup server was unavailable, or if backups had been deleted from it, they could still be restored from the...
