  1. "VLAN Aware" - inconsistent in behavior when adding tag inside qemu guest. Why?

    I have two proxmox installs. They are both 7.2-3. One has is running on a HP ProBook G7 laptop. It has a single RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller. The network config is below. On this system, I run a opnsense router VM. It has two interfaces. My WAN is tagged on VLAN 44...
  2. Moving disk from one system into another

    My current proxmox "server" is a very old i7-4770k, 32G and a z87-c motherboard. The system is running latest proxmox 7.2-3, full up to date as of posting and boots in UEFI mode (but no secure boot). The "boot" volume is a 2.5" 60GB SATA SSD, and the server has a 2 TB NVMe drive which is used...
  3. Why can I not choose the storage destination of a powered-off VM when doing a migration?

    As in title. I setup a 2nd server in my lab to do testing, it only has a "local-lvm" storage. I setup some VMs on it. Now that I'm done testing - I'm decommissioning it and I need to move all my VMs off from this test server and onto my main one. But when I go to migrate powered off VMs, I...
  4. [SOLVED] Changed root pw on proxmox backup server & proxmox host - cant re-add backup server to proxmox

    So last night I changed the root password on both my proxmox host server & my proxmox backup server. The new password works fine to log into ssh/webGUI etc of both systems. I deleted all historical backups, then removed the proxmox backup server storage from my proxmox (starting fresh)...
  5. iGPU Passthrough on PVE 6.3-3

    Hello Everyone I've been wrestling with this all day, hoping someone can help. I have my iGPU onboard GPU passed through to a vm running windows 10 build 2004. Qemu utils are installed on this system. It's using OVMF bios (UEFI). I used the instructions in the documentation to set this up...
  6. Ceph Cluster - loss of one host caused storage to go offline

    Hi There, We've got a 5-node ceph cluster with 10gbps networking. All hosts have 3 x HDDs in them for "slow" storage, and all hosts but 3 have SSDs in them for fast storage. Hosts 1,2,3,4,5 all have 3 x HDDs in them - we used this for anything that needs "Slow" storage. Hosts 1,2,4,5 all have...
  7. Adding SSDs to improve Ceph performance

    Hi all. We've got a 3-node ceph cluster that contains 4 x 6 TB SATA drives experiencing very poor I/O write speeds. I do have WAL and block.db on fast SSDs but they are too small for our workload. So I've installed one enterprise SSD (1.2TB) in each host. First off, I am wanting to create a...
  8. Ceph OSD Down & Out - can't bring back up - *** Caught signal (Segmentation fault) **

    Hi, I noticed that in my 3-node, 12-osd cluster (3 OSD per Node), one node has all 3 of its OSDs marked "Down" and "Out". I tried to bring them back 'In" and "Up", but, this is what the log shows: My setup is WAL and block.db is on SSD, but the OSD is SATA HDD. Each server has 2 SSDs, each SSD...
  9. Containers not starting.

    Hi All, I've got some containers that won't start up after an update. Nothing special about this container - it is on local storage (NVMe), but it just won't start. Proxmox says its running, but the console shows a black screen and I can't connect / ping over network. Other containers are...
  10. AppArmor, NFS Mounting

    The guide (https://pve.proxmox.com/wiki/Linux_Container) says
  11. Proxmox Ceph - Connect external workloads to proxmox Ceph

    Hi, I’ve got a 3 node proxmox cluster running ceph. I’m also running Kubernetes on top of proxmox. Currently, my LAN is 172.16.254.0/24 and my Ceph network is 10.10.10.0/24 (separated over a different NIC and VLAN) How do I give my Kubernetes access to Ceph? I want to create a separate...
  12. Proxmox 5.2 + Ceph Luminous

    Hi, I'm just wondering if with proxmox, running ceph monitors in a different subnet is a supported configuration? The official guide that walks you through configuring monitors only gives the option to create OSDs running on the nodes themselves, i..e on the one subnet (as defined by the...
  13. How do you dist-upgrade LXC containers?

    As in title. I am running 17.04 now which is EoL as of Jan 2018. As a result apt etc are not working. If this was a VM, I'd just go the dist-upgrade route. Is there an easy way to upgrade the container(s) from 17.04 to the latest version 17.10 or 18.04?
  14. Moving from ext4 storage (.raw) to thick provisioned-lvm

    Hi, I thought this would be as simple as creating a backup & restoring - but it looks like it is not. Restoring it to my lvm (thick) storage gives this error. TASK ERROR: unable to detect disk size - please specify mp0 (size) Restoring it back to the ext4 datastore (where this ct originally...
  15. pveceph stop and pveceph purge

    So I completely messed up my ceph config in my test environment. I read that running "pveceph stop" then "pveceph purge" will remove all config & data. So I did. Then I went to the Ceph guide (https://pve.proxmox.com/wiki/Ceph_Server#Ceph_on_Proxmox_VE_5.1) and began creating my cluster again...
  16. Removal of failed node

    A few months ago one of my nodes (3 node cluster) failed. I replaced it with a new machine at around the same time, then added another node. (So now we have 1 dead node, 4 live nodes). I went through this documentation to remove the node...
  17. Can't start ct after stopping it

    Hi, I am running a 3-node cluster. I stopped a container to make some changes to the hardware. When I went to power it back on, I couldn't. When I press the "start' button, I get a spinning 'Please wait' thing for a while. Then eventually it says "Timed Out". I ssh'ed into the host itself...
  18. Proxmox 5.1 nested - assistance needed

    Hi All I've got Proxmox 5.1 running as a VMWare ESXi guest. So far everything seems OK. I need to run several Linux CT and one Windows 2012 R2 VM. I have so far set up a single VM on ESXi and installed proxmox on top. It's all working properly, and I've followed the "Nested Virtualization...
  19. Large-scale migration from VMWare to Proxmox (Ceph)

    Hi, I'm working on a project right now where I've got a number of vmware VMs (approx 50) taking up approx 5-8 TB of space. They're running on a VMWare cluster. I've also got a 3-node proxmox cluster setup with Ceph up and running - ready to migrate off VMware to Proxmox/Ceph. I've done this...
  20. Ceph Journal on SSD

    Hi All, I've got 3 servers each with 4 x 4 TB disks and a 500 GB NVMe SSD which I'm wanting to use as a journal for each of the disks. I've created 5 x partitions on my SSD, the first partitions being 2GB each (one per 3TB disk) and with the remaining space I've made 1 partition which I'll use...
