I recently migrated some of my infrastructure to Proxmox and now run my first 2-node cluster using a qdevice for quorum. Each node is connected to a Synology NAS over NFS. The setup works smoothly overall, except for backups. With qcow2 disks on NFS, the CBT (changed block tracking/disk...

Hi everyone I just set this up a few days ago. Setup went very smoothly (no errors). But when testing, seem to be running into an issue when I reboot one of my two nodes. It says something like "No quorum on node1" in Datacenter -> HA (where node1 is the remaining online node). From what I...

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...

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...

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...

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)...

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...

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...

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...

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...

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...

The guide (https://pve.proxmox.com/wiki/Linux_Container) says

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...

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...

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?

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...

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...

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...

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...

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...
