For non-users of either Proxmox or Suricata: the first one is virtualization appliance which helps firing up virtual machines as well as LXC containers and the latter is network traffic security system which is able to identify (IDS mode) or even block malicious traffic (IPS mode). Suricata works just fine on Proxmox which is usually installed on Debian Linux, but sometimes there are some hardware/software compatibility issues which I’m going to tell you about right now… Having Proxmox server exposed in public space could be really not the best way possible. However if there is no chance for dedicated hardware,
First of all this SSD drive which I use is somehow faulty. It is a Goodram SSDPR-CX400-01T-G2 drive of 1TB. It have been working fine for few weeks until some construction worker made a electric short causing some abnormal frequences in wires resulting a faulty drives and memory sticks. One of victim was this drive: This drives for sure has some issues as at least one of tools shows that it as a problematic badblocks. Second of all in regular use it fails to run VM. It once switched into read-only mode in VM filesystem then after formatting it it
You can put your #GPU in #Proxmox server box and pass thru computational power to virtual machines… just in case you would like to run your AI/ML things alongside your virtualized NAS 😀 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
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.
