I have installed multipathd and using it. I have one dm-xx device that is the multipathed version of the 4 paths I have. I can see this dm-xx on all the nodes. While I can create an LVM on this dm-xx, I can't create a shared ZFS. I'm just curious what is preventing that, when ZFS over iscsi can...

Hi again, It seems that I can create new VMs on other nodes. The failures are not consistent. I also did a live migration of a running VM, while another VM can't be migrated (and it does not have any config that prevents it from migrating). Any ideas? Sp

Hi all, I have a proxmox 5.2 setup with 3 nodes and I have an LVM volume (it resides on SAN over FC) shared between the nodes. I brought up a VM on node1 and I successfully migrated it to node2. The problem is that now it seems that only node2 can create new VMs on the LVM. Also I can't...

Hi all, Since proxmox supports shared ZFS over iscsi, I believe it is possible to have a ZFS shared LUN over FC. As far as I can see, the GUI only supports ZFS over iSCSI. Is there a way to manually configure a shared ZFS LUN over FC? Thanx, Spiros

Hi all, Cluster creation via GUI is a very nice thing. I would like to ask if I can create a cluster with both ring0 and ring1 networks via GUI. The GUI allows you to put only the ring0 address. If it not possible, can i add ring1 later via cli? Thanx, Sp

Is it? ZFS over iSCSI (FC in my case) is mentioned in the "Storage" wiki, as supporting "shared" Regards, sp

That's true, but for my case I will present one LUN, that is shared among many VMs (via LVM), so I don't want to snapshot all the VMs at the same time. Each VM should have its own snapshoting capability. sp

Hi all, What about ZFS? Does it offer all the features you can get? Sp

Hi all, I would like to build a 3node proxmox cluster that will use a 3par storage over FC. It is not clear to me, what are my options for setting up the storage. For now, I have setup multipathd on all 3 nodes and I have a LUN that all 3 nodes can see (each node has a dm-x device that...

HI all, I am creating a ceph cluster that has SSD disks. I would like to know if it is better create a RAID 0 for each disk (1 Vol for each disk) and then give this to Ceph or just give the native SAS disks. The hardware is standard HPE DL380. I have this feeling that the Raid setups are...

Hi all, I would like to give to different customers VMs, each with its own IP. I have a /24 for that purpose. How do I restrict the VM to have this particular IP? The customer may assign a different IP on the VM interface and of course this should not be allowed. My search showed firewalling...

Hi all, I have installed the latest proxmox and I have setup just one VM with the following config: bootdisk: scsi0 cores: 12 cpu: Skylake-Client ide2: local:iso/xxxx.iso,media=cdrom memory: 32768 name: vmtest net0: virtio=0E:E3:06:DD:23:F3,bridge=vmbr0,tag=617 numa: 1 ostype: l26 scsi0...

Hi all, A question to Proxmox: Is it true that download.proxmox.com (the repo host) sends jumbo frames which are fragmented along the way by your routers? I'm getting fragments which are reassembled at the destination (my proxmox host). If the above is true, let me tell you about a scenario...

Hi Wolfgang, Yes the config was the same and the IPs were resolvable via /etc/hosts. I also tried to remove a node and readd it but this also didn't work. Now, I have reinstalled proxmox and I will try again when I have my network config stabilized. Anyway, It would be nice if someone could...

Hi all, I have 3 proxmox servers, each with a 4*10G ethernet adapter. I also have two 10G switches to connect them to. The nodes have disks on them to implement a ceph storage and they will also host VMs. I would like to have redundancy in case of a switch failure/reboot, for storage, cluster...

Hi all, I tried to setup a cluster of 3 nodes and I run into problems. I want to setup two interfaces on each node for the cluster (primary/backup) and I tried to follow this: https://pve.proxmox.com/wiki/Separate_Cluster_Network#Configure_corosync * Note: the cluster right now is not in a...

Hi all, I have a proxmox cluster with 3 nodes. I have Windows Data center licenses for the *2* proxmox nodes and I have a few windows server VMs on this cluster, on the licensed hosts. How can I restrict proxmox from migrating windows VMs to the unlicensed host (when I have a failure)? Is...

Hi all, Thanx for the answer. If we use the LVM over iSCSI solution, does this mean that we can't backup a VM, because we don't have snapshots? One more stupid question. When we say that LVM over iSCSI can be shared storage for proxmox, does this mean that all proxmox machines can see a single...

Hi all, We would like to setup 10 new servers in a proxmox cluster in order to run our workloads (VMs). We also have an 100TB EMC storage that will be used for storing VMs (over iSCSI at 10G). I would like to know what is the suggested storage setup for our hardware and setup in order to have...

Hi all, I would like to ask if Proxmox 5.0 supports IOMMU/ACS for passthrough ethernet adapters (intel XL710) when the hardware is a new Dell R740 with Xeon Gold 6126 (of course, I don't have the HW yet or I would try myself). The new Xeon Gold family does not state VT-d support or ACS support...
