  1. ZFS via iSCSI using LIO/targetcli

    Hi, If I see it right, proxmox currently (5.1) does not really support ZFS via iSCSI on up to date versions of Linux. "Linux" support for ZFS over iSCSI found in proxmox today means "IET", which has been deprecated for quite a while unfortunately. I've looked into how IET support has been...
  2. Add storage to VM (iSCSI)

    Hi, I just started with virtualization a few weeks ago. I have got an Ubuntu VM running in Proxmox and I have added an iSCSI disk (created on my Synology NAS).

  8. Configuring shared storage

    I have already a cluster of 3 nodes and I would like to enable proper VM Live migration, i.e. unnoticeable downtime. Right now I have my VMs using local-lvm (LVM-thin) and therefore live migration is not allowed (you can use --with-local-disks but there's noticeable downtime). Could anyone...

    Hi guys, I am struggling since 4.4-12 to 5.1-36 upgrade (to be fair it's a new deploy) due to terrible I/O performances via iSCSI (but after some testing also NFS seems affected). The problem doesn't always show up, but I have been able to reproduce it in this manner: VM just booted up with...

    I am using a Dell Compellent SAN that has multiple controllers and I would like to get Proxmox to log into both sides of the SAN. I see in the interface it only seems to want to allow me to log into one portal. Do I need to modify the storage.cfg file in /etc/pve ? Or do I just need to add the...

My intention is to be able to start up my VMs on any of the 6 nodes, given that there is enough resources available. Now I have a VM set up on node A, and I'm confused about how to move it to node B. 1. If I try...
