    Hello I'm reaching out to this community as I'm just starting out with Proxmox and could do with some advise. Does anyone have any experience of using a Dell MD3600i SAN with a Proxmox cluster? We are very early in the planning stage and we are trying to do the best possible setup with...

    iSCSI LUNs or VM image LVMs slows grub during updating PVE

    Got a 4.4 production cluster attached to a multipathed iSCSI SAN from a HP MSA1040, divided the MSA into two disk groups A&B, then created 5+1 xiSCSI LUNs per MSA disk group and mapped those to PVs in four volume groups on each hypervisor node like this: vgXbck LUNs are mapped to nfs server...
  3. iscsi: connect to existing lun

    I want to connect an existing iscsi lun to Proxmox. I added the iscsi target (successfully), but I couldn't access the data. Does anybody know how can add an existing luns into proxmox? (am I missing someting?) and where for is the option "Use LUNs directly"?
  4. 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...
  5. Adding ISCSII From GUI

    I believe I have done this before without a hitch. Other sources seem point to adding ISCSI LVM as well however, I am not able to add an LVM its asking me to select a Base Volume. What step did I forget to do?

  8. 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...
  9. [SOLVED] Moving container between LVMs

    Hi All, Proxmox 4.2-18 Proxmox is attached to a SAN, which has a large LVM presented, and is in use for some containers. Co-worker created 20/30 new containers on local LVM (only 800GB) by accident, what is the correct way to move these to another storage? downtime is no issue as these...
  10. Migrating from XenServer, use existing LVM over iSCSI

    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...

    Hi We are setting up a cluster of Proxmox ver 4.2 hosts using shared LVM Groups with Network Backing via 10GB ISCSI to a Dell MD3800i SAN. Just looking at the following post for Proxmox ver 1 it mentions that we need to consider using CLVM...
  13. FreeNAS iSCSI issues with Proxmox Cluster

    Hi, we have setup a 3-node proxmox cluster (4.1) and configured two storages for VMs - NFS to our FreeNAS and iSCSI to our FreeNAS. iSCSI was configured using Proxmox Web UI (https://pve.proxmox.com/wiki/Storage_Model#LVM_Groups_with_Network_Backing) Both, NFS and iSCSI, use dedicated 10G...
  14. [SOLVED] No access to LVM over iSCSI after a node reinstallation

    Hello community. (this is my first post :)). I was working with ProxmoxVE from the 3.0 version.

Thus tasks such as updating, re-installing nodes, configuration of different types...

    Hi I have a two-node cluster up and running. My SAN storage (Dell MD3220i) have 4-port controller, and I attached one server in each port directly (without switch). Each storage port have one different portal, I can't reach the iscsi target with the same portal. In the proxmox environment, I...
  18. Pve 4.2-2: Volume Group disappears using LVM on multipathed iSCSI storage

    Hi all, while working on a small cluster with shared storage on iSCSI, I've noticed a problem with multipath that I can consistently reproduce. I've done some tests with a single (non clustered) node to exclude problems related to the cluster setup. I've tried with and without multipath and the...
