  2. Installing Proxmox on iSCSI target

    Hi, I followed the guide on the wiki at Proxmox ISCSI Installation, but instead of installing Debian Stretch I choosed to install Debian Buster in order to install Proxmox 6.4. Following the guide is not hard and it works fine until the step where one should install the "pve-kernel"-package...

    Following instructions found here: https://pve.proxmox.com/wiki/Cluster_Manager Did a fresh install and after creating the cluster on an existing node, I went thought the join process via the web GUI. After completing it, I appear to have a cluster. So I decided to play with a machine...
  4. [SOLVED] Need help configuring ZFS over iSCSI

    PVE 6.4-6 on both nodes I'm trying to set up ZFS over iSCSI to share disks in my cluster. I have followed the instructions from the official docs. I confirmed that I can log in to each node with ssh -i /etc/pve/priv/zfs/192.168.1.1_id_rsa root@192.168.1.1 replacing the IP with each node's...
  5. iSCSI battle: give it to PVE or give it to VM

    Hello friends! I want to open up a debate - well, I was hoping to - about the iSCSI disc space assignation. The thing is: let's say that I have a server with several storage spaces and that server is connected to PVE. For the purpose of this, let us not go into the matter how they are...

  7. Adding a cluster node with Shared LVM/iSCSI and multipath

    What is the proper set of steps to add a new node to a cluster when using shared LVM over iSCSI and multipath? I have had mixed results with this. I've been migrating my servers from ESXi to Promox one at a time. Adding the first 2 nodes to the initial Proxmox host cluster went fine, But the...
  8. iSCSI storage encryption for a cluster

    Hello, I am setting up a Proxmox cluster with 3 servers, and 1 shared iSCSI storage. It seems that I can only access this storage in iscsi mode (I asked a question about this at https://forum.proxmox.com/threads/zfs-via-iscsi.74843/post-378849) With this setup, what are my options for VM...
  9. iSCSI: storage '<name>' is not online, VM working, no possibility to backup and/or migrate

    Hello! I'm running a PVE 5.2 cluster with 4 nodes. The cluster is attached to a SAN, an HP P2000 G3 iSCSI. VMs are hosted on the SAN. The first controller of the SAN failed. Everything is running on the second controller, but I can't manage PVE anymore. Although VMs are running, it seems that...
  10. NFS vs iscsi

    I see a lot of organization using NFS instead of ISCSI for vms and data storage. It's apparently more to ease operations: backup can be done on the vm files and do not require a separate server. Is this true? How much performance you are really losing when using NFS instead of ISCSI? The only...
  11. nfs looks trendy on the proxmox platform: so nfs or iscsi ?

    I recently discovered that a lot of people around me are using nfs instead of iscsi on a PVE platform. The main reason for it seems that it’s easier to backup an nfs-based solution thaan an iscsi one, since on The remote disk everything is a file. Is this a general trend? What would bring...

  14. backup server with remote storage or USB? (edited)

    So waiting a proper baclup machine due to limited supply. I would like to start to use the proxmox backup server. The size of backup sholdn't be large. At max probably 1TB on disk. I have an unused spare machine with 2x10Gbe + 4x1GbE, 2x240 GB SSD and 16GB RAM. The storage can't be expanded...
  15. [SOLVED] Ceph & iSCSI HA - How to configure the network?

    I am looking to some guidance to finalize the setup of a 3-nodes Proxmox cluster with Ceph and shared ISCSI storage. While it's working, I am not really happy with the ceph cluster resilienc and I am looking for some guidance. Each nodes have 2x10GbE ports and 2x480GB SSD dedicated for ceph...
  16. [SOLVED] How to initizlize remote iSCSI LUN device with multipath?

    I have exported an iSCSI LUN with multipath to a PBS server in the SAN. How should I initialize this remote disk? It doesn't show up in drive list. # lsscsi [1:0:0:0] cd/dvd QEMU QEMU DVD-ROM 2.5+ /dev/sr0 [2:0:0:0] disk QEMU QEMU HARDDISK 2.5+ /dev/sda [3:0:0:0]...
  17. iSCSI help with Proxmox 6.2-15

    Hi All, I was able to successfully get an iscsi target hooked into my environment. As a test I created a vm - but it obviously used the entire 2tb disk. I then read that I should create an LVM on top of the iscsi and went through the setup wizard only to find the cfg.lock problem that seems...
  18. Another iscsi/multipath question

    I "think" I have this configured correctly but wanted to see if there was others that might know better. Step 1. in GUI add a new iscsi pointing to the iscsi portal and adding 1 target. (also uncheck Use LUNs) Step 2. Add node-startup = automatic to /etc/iscsi/iscsid.conf (Restart iscsi...

    Hi all, I'm new to Proxmox having been running VMWare since maybe 3.5 or something. Decided to switch over because I wanted to take the cheaper path to Infiniband and then found the support in VMWare not quite there. My setup now is Proxmox server with a dual-port Mellanox ConnectX-3 card. My...

    Hi, I've upgraded one of our clusters from 5.4 to 6.2 only yesterday and unfortunately cannot start VMs using iSCSI storage using the UI. The logs don't show much, all I see there is Error: start failed: QEMU exited with code -1 Researching the forum I read that errors like these are likely...
