    firewall bug or weird behaviour

    Hi all, I came by some weird behaviour i don't understand and I would like some help. I have a cluster (5.2) and I have a VM on a node. I am trying to prevent the VM of changing its IP. I have configured the "ipfilter-net0" ipset and as far as i understand this corresponds to the following rule...

    LVM over FC sharing

    Hi, No i didn't. I just used the GUI. 1 or 2 VMs were created on node1 (the master node) before creating the cluster. Sp

    LVM over FC sharing

    Hi LnxBil, You may find LV,VG,PV at: http://ajax.noc.ntua.gr/~papage/lvm.txt Basically there is one VG on the FC LUN and then there are LVs that corresnpond to a few tests I made. Keep in mind that migration and creation of VMs works sometimes and sometimes it doesn't. I'll need to do more...

    ZFS shared storage over FC

    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...

    LVM over FC sharing

    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

    LVM over FC sharing

    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...

    ZFS shared storage over FC

    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

    proxmox 5.2 GUI cluster creation

    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

    proxmox HA on shared SAN storage

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

    proxmox HA on shared SAN storage

    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

    proxmox HA on shared SAN storage

    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...

    CEPH disks on RAID 0 or not

    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...

    Restricting IP on VM interface

    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...

    proxmox repo host behaviour

    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...

    cluster changes - corosync

    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...

    network setup and redundancy

    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...
