I have a Proxmox Backup Server making regular backups of a VM on another machine, and it works fine. But I find it hard to restore just a single file. According to the wiki, it's possible to restore a single file, but I can't find the "File Restore" button in the GUI? I can do it via the...

My Proxmox host has a large disk that I use to host a mirror of a Linux distro. The disk is attached to the VM via sshfs. This may not be so fast, but it works, and it's easy to exclude the large disk from the daily backups of the VM. There's no reason to backup a mirror.

Thanks for all your input. I guess more RAM is the way to go. But on the short term, will it make sense to limit ZFS ARC, in order to keep the VMs running and prevent these OOM situations? Something like echo "8589934592" > /sys/module/zfs/parameters/zfs_arc_max I much prefer living with...

Thanks for your info. Yes, to little RAM is probably some of the problem. I have 32 GB, that may no be enough but I believe it's all my server can hold (HP Proliant Gen10 Micro Server). I have a HDD with extra space, but now it only holds the ext4 partition. I guess I can reduce this partition...

Today I tried to transfer a lot of photos (5 GB) from a disk, mounted via sshfs, to one of my VMs. This caused the Proxmox host to put full blow on its fan, and it became totally unresponsive. On the screen it showed messages about being out of memory, and killing and reaping kvm. After 10...

I have a cluster setup with two "real" nodes, and one Raspberry Pi used as quorum device, see my corosync.conf below. All three nodes are connected to two networks, 10.10.10.0/24 and 192.168.1.0/24, with the 10.10.10.0/24 network being used only for cluster communication. I can add ring1_addr...

Great! Here's what I've now done: Put this script in /usr/local/bin/backup_hook.sh (my external disk is mounted as /mnt/intenso) #!/usr/bin/env bash grep -qs /mnt/intenso /proc/mounts if [ $? -ne 0 ]; then # skip backup echo "Skipping backup - disk not mounted"; exit 1 else # continue...

OK, I managed to fix it, I hope. Unfortunately, the external disk I use for nightly backups weren't mounted, so this night Proxmox placed the backup on the local filesystem, filling it totally. Removing the local backup-file solved the problem.

This morning, my VMs on my Proxmox server weren't available. I remember message like "No space left on device", but not quite sure. I've tried several reboots. The machine boots, but the VMs and the GUI don't start. df -h shows Filesystem Size Used Avail Use% Mounted on udev...

Something like #!/usr/bin/bash if grep -qs '/mnt/backupdisk ' /proc/mounts; then # do backup else # skip backup fi

Each night I make a backup from Proxmox to an external HD. With a backup hook script I can check if the external HD is mounted, before the backup job is run. But can I also, in the hook script, prevent the upcoming backup if the HD is not mounted? Jesper, Denmark

Hello Dylan, thanks for your interest. To make my USB-stick accessible from the VM, I did: $ qm monitor 100 $ device_add usb-host,vendorid=0x781,productid=0x5583,id=someid # pveversion -v proxmox-ve: 7.1-1 (running kernel: 5.13.19-2-pve) pve-manager: 7.1-8 (running version: 7.1-8/5b267f33)...

Hello Dylan, thanks a lot for your suggestion, but it's too late. But it's also good to know, should this happen for me once more. The VM acts as mail and web server for a few domains, so after a few hours, I decided to reinstall from my backup. Fortunately this went smoothly, but resulted in...

Thanks a lot! It worked! :)

Hi Fabian, Thanks for your reply and suggestions :) Is the info below of any help? # lsblk -o NAME,FSTYPE,PARTUUID /dev/rpool/data/vm-100-disk-0 NAME FSTYPE PARTUUID zd0 ├─zd0p1 xfs 00098968-01 └─zd0p2 LVM2_member 00098968-02 # lvs WARNING: Not using device...

Yesterday I had serious problems with one of my VMs, and I was forced to recover from a backup. But the data from the VM are still on my disks, running zfs: lrwxrwxrwx 1 root root 9 Jan 6 12:55 /dev/rpool/data/vm-100-disk-0 -> ../../zd0 lrwxrwxrwx 1 root root 11 Jan 6 12:55...

I have a small cluster with two hardware servers, HP1 and HP2. On HP1 I have a VM (Centos), running as HA, and everything have been running fine for a long time. Today I tried to copy a lot of files from a USB-disk to the VM, and then everything seemed to stop. The GUI interface to Proxmox was...

Thanks again - the number of options is really overwhelming :) I have this small cluster, only 2 "real" nodes and 1 "quorum" node on a Raspberry Pi. What I really want is to be able to share storage between the two "real" nodes, so I can easily move VMs between the two nodes, and also have one...

I'm sorry for my late reply ... It seems I don't really understand how to handle storage in a cluster. I thought that with a lot of free disk space on node "lasse", it would in some way be possible for me to use this space for shared storage. Most of the disk space on "lasse" is used for a zfs...

Thanks for a quick reply, but I can't find a Content tab anywhere. For one of the nodes, "lasse", nothing shows under VM Disks and CT Volumes: The other node has a VM Disk, but show no Content tab:
