...any snapshots? What filesystem are you using and is it ‘trimmable’ (just removing files doesn’t mean you can actually zero sufficient blocks to reduce disk space). Is your VM disk image larger than the underlying capacity? Perhaps you can shrink it to a ‘safer’ size (90-95% if it’s the only...

...larger NVMe, I want to fully utilize this space for new containers (like Batocera and Home Assistant) and existing VMs. My current goal is to shrink my pve-root Logical Volume (which hosts /) from its current excessive size down to a more reasonable 50GB. The substantial amount of space freed...

feels free to ask for any info u guys require to fix this issue i also want to shrink this windows vm since i allocaed too much storage but over 2tb i cant format after gparted it gives some error might be because ssds are in raid0 2tb+2tb and i allocated around 3tb to this windows vm and i can...

...+ ECC though) in a Mini-tower like HP ML110/ML310, Lenovo ThinkStation and so on. Those consumed 60 to 80 Watt per node and I saw the need to shrink down. Only one HP MicroServer is left today, utilizing ~30 W or so. The others got "recycled" and became excellent PBS's, turned off most of the...

...Any SMB-tier company will have a NAS they expect to use for hypervisor backups. Sure, an iSCSI LUN works—but you can only expand it, not shrink it, which sucks away a lot of flexibility. This is my second rant on the Proxmox forums, and it’s still a rant because while the project charges...

...first before attempting this. Then check the actual used size inside the CT with df -h and add at least a few gigabytes or so. Do not shrink the file system lower than that. Shut down the CT and try this pct shutdown 100 # Find CT disk(s) ls -l /dev/mapper/*vm* e2fsck -vf...

...my clients (I'm a freelance Postgres DBA and need to keep development / scratch machines separate). It would be nice to be able to grow and shrink resource usage even more and it got me wondering about hotplug memory and CPU. I discovered that NUMA needs to be enabled in order for this to...

...comand to restore it: pct restore 201 /mnt/pve/nas30-bck/dump/vzdump-lxc-201-2025_05_24-02_59_35.tar.zst --rootfs 7 --storage data Now my restored container is 5.63/7 GB when previously it would fit in 4GB. Is this normal? There is something to enable or that I can do to shrink back CT...

...restarting the VM with a full shutdown and power-on, in hopes it would do a reclaim on boot a LVM-resize with 0 through the GUI, which didn't shrink the used space. The thing that did work (*within the VM as root to avoid the reserved 5% of filesystem space*) dd if=/dev/zero of=/zeros...

...up a new VM. I feel like open ZFS needs an extra tunable, where you configure min available memory, if it falls below that, then the ARC shrinks. Then you could have best of both worlds, a high max size, but it would only do that if there is a large amount of free memory. I will do a...

Interesting article, thank you! Yes, probably. But to my (very limited!) understanding it is slow. (Edit: I mean specifically shrinking the size, not its function.) When a single process (one VM, one KVM process) requests a large block of memory, the kernel can NOT force ARC to shrink during...

...low, and max much higher, but the max is dependent on having available memory, as well as enough data to cache. As a rule of thumb this will shrink much better than the old linux page cache, ARC doesnt usually cause OOM's or swapping. The ZFS dirty cache is not quite as polite, and is less...

Sorry for late answer.. If your partition table is gpt, doing the qemu-img resize -f raw --shrink rbd:<pool>/<disk-img> <size> you will drop it (usually gpt partition table stay at the end of the disk). So you need to rebuild it from scratch.

VMs will use what they are allocated. You can enable ballooning to shrink VM RAM if the node is full…over 80% by default.

That's what i am talking about. In a new install scenario with only a ZFS pool, it automatically adjusts the ARC-cache size to the from Proxmox suggested 10% of RAM - but not if you add a ZFS pool after the installation. I'm pretty sure this is not intentional and would be a hurdle for many...

The default min for ARC isnt 50%. In addition ARC is less aggressive than the old page cache. It will shrink better, and is actually configurable. For people who like to control their cache overheads, ARC is the best out there. I also would only consider using ext4 for root, maybe if its MBR...

...are well underused. From what I can gather, that would mean I need to free up space in the pve volume group, which I can achieve either by shrinking an existing logical volume, or adding more storage to the volume group. Shrinking seems viable, since both pve/data and pve/root have plenty...

This can be done in PVE too and depending on the storage backend (e.g. ZFS and to less optimized extend CEPH, LVM-thin), you don't need the Optimize-VHD run, just fstrim and everything else is done automatically.

In Hyper-V, if i want to shrink a vhdx runnig i.e. Ubuntu as guest os, i can shrink the virtual disk by first setting all unused blocks to 0 with sudo fstrim /, shut the vm down and on Powershell run Optimize-VHD virtualdisk.vhdx -Mode Full. Optimize-VHD obv. works by detecting all unused blocks...

...mountpoint /Data nodes proxmox If I understand what you are saying correctly, proxmox does not pre-allocate that space, so if I have 8TB disk space with 2 VMs, all of them with (let's say, for the sake of my understanding) 8TB, but as one fills up, the other one will shrink, correct?
