Hello!
Thank you for reading my post!
I'm creating my first Windows 11 VM on Proxmox and I was wondering what are the best settings for the storage?
I want it to be fast so I'm looking for the settings that would provide the best performance.
I'm using a DRAM-less SSD to store the disk of the...
Hi guys,
I'm still confused about the bdev_enable_discard & bdev_enable_discard options in Ceph, if this option is activated will it trim (clean unused blocks) automatically?
I have activated it, but I don't notice any changes. and it looks like it's still the same as usual, you have to use...
Hello everyone,
I’m reaching out to you all as I’ve encountered a bit of a puzzle with my mini PC setup. I’m fairly new to this, so any guidance would be greatly appreciated!
Here’s my current setup: I have a mini PC equipped with a 1TB NVMe SSD and a 1TB SATA HDD. I’m running Proxmox on the...

On PVE 8.1, I have a thin pool on NVME with a few containers.
I deleted one of the containers (via GUI) and now I am not sure if the space used by the LV was discarded/trimmed. I can't issue an `fstrim`, unless it is against a directory, nor I can issue a `pct fstrim` against the CT because...
I am currently migrating some VM disks from internal drives to multipath iSCSI. I am new to iSCSI and so am wondering about best practices for PVE VM disks hosted on there.
By default I have all VMs set to Discard and SSD emulation, but I am now wondering if those settings make sense on iSCSI...
I tried to use the discard feature of the virtual disk. I mapped a Huawei storage LUN to proxmox via FC link and added it as LVM-Thin storage. The discard option is selected when the VM disk is created. After the virtual disk is deleted,The proxmox page shows that the space of the LVM-Thin...
Hello
Since I've enabled replication between a remote server and one of my VM I notice a constant increase of storage. In fact, when I discovered it when I reach 100% of my Thin-provisioning capacity on the data pool. So after reading a couple of threads, I found that I need to enable the...
VMs with Debian 10 or Ubuntu 20.04 configured according to instructions https://pve.proxmox.com/wiki/Shrink_Qcow2_Disk_Files#Linux_Guest_Configuration
fstrim -av writes that he successfully released about 10Gib
But! qcow2.img size not changed (VM fs size 7.7G and qcow2 size 20G)
After poweroff...
Hi everyone,
I have a guest VM which seems to be unable to utilize the discard option to free up block space. The guest VM is a Ubuntu 18.04 LTS OS with an ext4 root FS. Underlying storage is Ceph on Bluestore OSDs. VM storage controller is VirtIO-SCSI, with just a standard 1TB disk attached to...
I have a cluster that has relatively heavy IO and consequently free space on the ceph storage is constantly constrained. I'm finding myself performing fstrim on a more and more frequent interval. Is there a way to auto trim a disk for an lxc container?
Hello!
We have a couple of servers configured to use local ZFS pools for storage. These pools have Thin Provisioning enabled.
I used to think that Thin Provisioning + ZFS was enough to have the VMs use on physical storage the same space that they are using into themselves, but it seems I was...
About returning unused space (trim or discard mapped size disk)
I know about use `fstrim` command in guest vm.
But I can not login to the guest customers!
Now, my question is, is there any way to do this from within the host machine (main proxmox server)?
Hello to the community,
I was following this thread to find the solution to the problem, but I got different behaviour.
My guest VM is using 13GB on /dev/sda1, here's the configuration
bootdisk: scsi0
cores: 1
ide2: none,media=cdrom
lock: backup
memory: 4096
name: pippo001

Hallo,
ich möchte gerne eine VM mit Windows server 2016 installieren. Mein Server hat zwei SSDs im Raid. Für die Festplatte nutze ich qcow2 aber was ist das beste IDE, SATA or Virtio? Sollte man discard aktivieren oder aus lassen? Ich habe kein LVM Speicher.
Danke für jede Antwort, da ich...
Hi Guys,
on my Proxmox 5 I have to create several Windows 7/10 Virtual Machines.
My server has an hardware RAID Controller Card (1 GB RAM with battery) and 4 SATA Disks attached to it.
I would create the VMs with the following parameters:
-Hard Disk Bus/Device: SCSI
-target storage: LVM-thin...
