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...

    Snapshots on NFS or iSCSI

    Hi, I have a shared storage based on a NetApp system which exports through NFS or iSCSI. I am not able to make snapshot backups for LXC containers on NFS storage, so I am looking for something better. I read on https://pve.proxmox.com/wiki/Storage that even iSCSI does not support snapshot, but...

When I go to add a drive to a test virtual machine I click on storage and the "loading" animation is displayed but after a short amount of time it disappears and the storage box is empty. I don't...

    Faulty storage connectivity and HA

    We are trying to build HA cluster with iSCSI storage over dedicated network interface. Looks like disconnecting storage network (in any way - physical fault or misconfiguration) doent lead to any reaction from PVE HA. For example, if node connection to iscsi storage failed, we got messages like...

    Backup over Network to NAS

    So I'm looking for a solution where ProxMox does its backups over the network to a FreeNAS box. Last week I had this running very well using NFS until Tuesday morning when FreeNAS went offline. To me if the NAS goes offline the backup should quit and get over it, but it didnt do that. Instead...

    best practise for ZFS over iSCSI? (FreeNAS)

    Hi, I guess ZFS over iSCSI would be better than just use iSCSI share + LVM on top of the iSCSI share, since it gives the benifit of easy snapshot and clone right? So I have a new installation of FreeNAS to provide iSCSI. Is it best to use a new zvol and device type extend or a new dataset...

    Hello, I'm currently using Citrix XenServer 6.5 and considering switching to ProxMox (testing it with another physical server). I'm using a Synology NAS as the iSCSI server. XenServer created LVM over the raw iSCSI for the VM storage. I have cloned the iSCSI target/LUN on the Synology for the...
