  1. 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...
  2. 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...
  3. 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...
  4. 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...
  5. Cannot start VM - KVM internal error. Suberror: 1

    I have been working on moving the storage of VM's from an NFS share on my TrueNas core server to a ZFS over iSCSI share on my TrueNas server. I have ZFS over iSCSI all set up and it appears to be operational. I transferred of one of the VM hard drives from the NFS storage to the ZFS storage but...
  6. Cannot Create LVM on iSCSI storage

    I set up a new instance of TrueNas 12 Core. I am attempting to setup iscsi storage to TrueNas in Proxmox. The vdev was created in TrueNas along with the iscsi target. I have created the iscsi connection in proxmox and it is showing as available but receive the following error when I attempt to...
  7. 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...
  8. [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...
  9. [SOLVED] How to initizlize remote iSCSI LUN device with multipath?

  10. 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...
  11. 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...
  12. Help setting iser transport for ZFS on 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...
  13. after upgrading from 5.x to 6.x, iSCSI VMs can only be started via commandline

    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...
  14. Accessing ZFS pool in VM

    Hi! I'm quite new to Proxmox, although I have some Linux experience previously, and I haven't found any working way to access my existing ZFS pool from an OpenMediaVault VM. Ideally, I'd like OMV to get access to the disk space directly without having to do a network share; this is purely based...
  15. iSCSI/LVM confusion with enabled storage options

    Hi all. Hoping for some advice and guidance for a new Proxmox user. I'm in the process of standing up a cluster of 3 identical nodes backed by iSCSI storage for VM workloads. I have created a bond of 3 NICS and defined the relevant networks for storage and enabled multipathing following the...
  16. iSCSI, cluster of Proxmox, corruption ?

    Hello, It's certainly written somewhere, but I didn't find it on https://pve.proxmox.com/wiki/Storage:_iSCSI It's said that it's generally not recommended to mount multiple iSCSI LUN on a host as it leads to data corruption. Therefore, how does Proxmox handle this when used inside a cluster...
