Finally I got it working. I think so. This Proxmox installation is simple one, just single node for experiments which is half part. The other part is VM configuration. You may ask, what exactly for do I need GPU in VM? I may need because the hardware is capable of running several additional GPUs and I can use all of them at once in different configurations and even in different operation systems. Just like people do in cloud environments and this setup mimics such thing running server-like computer with datacenter-like GPUs on board. During this test I used NVIDIA GTX
I installed Proxmox Backup Server several times, both on bare metal and virtualized inside Proxmox VE. This time I did it in PVE as virtual machine and encountered an issue while initializing disk with GPT, creating directory, LVM or ZFS. In other words, I was unable to create any datastore at all. So there is CLI that can help us: And that’s all, it works fine. In UI I got timeout. No idea why. Fortunately there is a alternative path.
There is not too much a precise documentation from Hetzner available if you want to know what exactly you should do to run dedicated servers with primary and secondary public IP, virtual machines and vSwitch. There are some articles but they are written in non-informative way. However their support is on very high level so far, they respond quickly. Debian & Proxmox Installation So, to go with Proxmox on Hetzner you will need to know that there is supported installation. You restart your server into rescue system (remember to power cycle your server) and then there is Proxmox to choose
I was replacing drives and memory in one of servers and out of a sudden node was unable to start. When finally it booted it was gone out of cluster. Weird. This node has been installed on SSD drive which had 2 years or constant runtime. Debian prompted with some file system issue at one and another time. After few reboots finally it booted successfuly but node was unable to communicate properly with other cluster members. I tried to start time synchro from the stratch to no avail. I pulled out other drives than this one with operating system without
If you log in to Proxmox’s shell and see error stating that “setting locale failed“, then execute the following command to get rid of that message: Not quite sure why it happens, but I see it almost all the time.
Image a hypothetical scenario having two 512 GB drives and want to use a Proxmox ZFS VM replication onto a second server with one 1 TB drive. Solution is quite simple. By using fdisk, create two primary partitions on the bigger drive and then go to Disks.ZFS.CreateZFS and you will be able to select a partition for the particular pool. One downside of such a setup is that ZFS liks to have whole drive for it’s own, please keep in mind that the performance may vary.
Having LVM on the disk causes system to automatically active such volumes. I installed used drive with Ubuntu on it to my Proxmox server. Using Proxmox’s UI you will not be able to wipe this drive, because volume group has been already auto-activated. You need to log into shell and then: After this, you are ready to wipe drive from the UI.
I own a preowned HP z800 workstation. As purchased it contained HDD inside – Western Digital WD5000AAKX-75U6AA0, SATA III, 500GB, 7200 RPM, 16MB of cache. Unfortunately it passes SMART and do not show wearout metric. However going into detailed information we get: Raw_Read_Error_Rate has positive value of 11, threshold is set to 51. Having 11 685 hours of runtime it should understandable that it might break and it did actually. There is only one Current_Pending_Sector which means that it waits to be remapped or rellocated. But, will it happen anytime soon? I’m unable to clone, migrate or replicate VM to
If you happen to use Proxmox’s LXC which stands for Linux Containers, then you might be interested in this one. Proxmox has this turnkey containers available to download from its UI. Among them there is WordPress. If you create a container using template then while creating remember to select nesting=on, because without this it will show permission denied on starting Apache2. Not quite familiar with nesting option but it is necessary to run this container.
