Keep in mind that although it really, really annoys me, and causes me concern, having 100% swap usage is not a bad thing *unless at that point things slow down*. Over the years, we have been told that Linux systems use swap when they run out of RAM and we have been taking that at face value. We...

Well, Proxmox *supports* a clustered environment, but does not *require* it. Many of us do not use it to the full extent of its ability. Many users only use local storage and may or may not have a cluster of a small number of nodes, mainly for ease of management rather than storage sharing...

I am disappointed to hear this. I would have thought a "repair" or "re-install" would be a very useful option to have. I do not know the complexities involved with installers, but if it is a simple thing to implement, please can it be added? I am horrified at the idea of probably losing my...

In the event of an OS or Proxmox software disaster -- for example an update that goes wrong, or accidental deletion of system files, or some other serious problem that cannot be resolved easily or prevents the system from booting or similar, can someone please tell me if there is a way to...

Although I have no experience of them myself, from what I have read here on the forum, these differential backups are a bad idea. Stick to full backups. Once you have a backup, how about copying them to something like Amazon S3? Amazon allows you to create a policy on a bucket that will move a...

I have used that .ISO without issues, but yes it is a bit strange. Essentially, you need to add your SSH key in the cloud-init setup (via the GUI), then login via SSH as user "Centos" (capital C). Once logged in, my memory fails me as to exactly what you need to do but it would involve...

Another option is potentially to fit an iDRAC Express. These are available for very little from ebay, A word of caution though: I recently purchased an iDRAC Enterprise for an old R310 from ebay. I didn't look to see where it was going to come from. It turned out it was shipped from China to an...

You *can* share a storage resource, but not out of the box, and not really via Proxmox itself. The basics are a bit like this: You would need to create Container (NOT a VM), and give it read-write access to a directory on the thumbdrive using "bind mountpoints". See...

When I choose a VM or Container in the GUI, and click in the Backups option, by default I can only see the backups that have been made in the default backup location (this being the first location ID, sorted alphabetically A>Z>a>z). I would really like to see all backups stored all at once, no...

I think we need more information. When you say you want to assign its own HDD, you mean you have, say, 4 physical HDDs on your server, and you want to use one for Proxmox, then one for VM1, one for VM2, and one for VM3? In order to be able to do this, you would install Proxmox on HDD1 (sda)...

I want to automate my VM backups but I'm not sure of the best way to achieve what I want. I want to backup each VM weekly, keeping a total of 4 backups EXCEPT for one particular VM, which has a huge disk volume, and I only want to keep one backup for this one. Adding to the complication, I...

I'm not sure how to test things in any significant detail, but I have discovered that there are three things that seem to affect how much swap gets used in my situation (which is different to yours but maybe there is a link) 1) I/O wait 2) Network traffic 3) Amount of free RAM on the Node...

I would love to see the same functionality you want. But the difficulty in achieving it is too great for this to ever happen as far as I can ever imagine. So, how about backing up your data in a different way? I have been investigating this myself. For me, firstly the backup must be to...

You don't need the Restoration VM to have the same resources as the real one. It only needs enough RAM to run Linux. 512Kb is usually enough. You can even get away with less, potentially. However, if you want to mount the backup on the Node, here are my notes about how to do so using NBD...

Sort of. Just not directly. There are multiple methods. One of the simplest is to restore the backup to a different VMID (you do this by clicking on the name of the backup when in the backup part of the GUI for the Node rather than in the backup part of the VM. If, like me, your VMs have...

How free RAM is there on the system? With that in mind, I cannot answer your question directly, but I can tell you that I have encountered a similar issue: In a container with OR WITHOUT swap, it is possible for applications running within the Container to cause 100% swap use on the Node, while...

I wonder if there's some confusion here? When you create an automated backup job (Cluster > Backups), it will create backups until the "max backups" set for the backup location is reached. At that point, it will allow one more backup, and then will delete the oldest backup. But when you...

Only certain types of "storage" (where the VM disk images are located) support snapshots. lvm-thin and zfs basically if you are using "local" as opposed to "shared" storage. https://pve.proxmox.com/wiki/Storage

Well, I've solve the problem, but still don't understand why it was happening. At the end of the day, I was seeing Node swap rapidly reaching 100% full when using the aws s3 cli in an LXC Container. Within the Container, little or no swap was being used, and little memory was being used. The...

Totally separate. The PVE firewall runs on the physical nodes and has no interaction with the firewalls within the VMs.
