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)
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?
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
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...
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...
