  1. Thin Provisioned Windows-VMs use full capacity in Proxmox Ceph after migration

  5. [SOLVED] ZFS - Belegter Speicherplatz größer als tatsächlich verwendet

    Hallo zusammen. Aus 4x 3TB HDDs habe ich einen RAIDz1 Pool erstellt, wodurch 7.7 TiB verfügbar sind. Den Pool nutze ich u.a. als Storage für zusätzliche Festplatten in den VMs (aktuell nur Dateien von der NAS-VM). Ein df -h innerhalb der NAS-VM zeigt eine Belegung von knapp 3 TB. Die Proxmox...
  6. Which MegaRAID is known to support TRIM?

    Used to rent servers (only a few, not that many) in datacenter, all under PVE and run perfectly well. Nowadays it is good choice to rent SSDs to put VMs on, and so we choose hardware raid with bbu to create mirrors out of SSDs (it is used to be megaraids) but... I never can find a wayto check...

    zpool trim in Proxmox 6.1

    Am I correct in assuming that I will need to create a cron job to run "zpool trim" on, e.g., a weekly basis? Because the "autotrim" property doesn't appear to be set on zpools by default (neither "zfs get all" nor "zdb" show it), and I couldn't find any existing cronjob or timer that runs "zfs...

    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)?
  11. PVE Installer 5.0 - possible to install on disk partition only (not whole disk on zfs)

    Would it be possible to take an entire disk (256GB SSD) and break it down into smaller partitions, then install rpool on a fragment of the disk only? Right now the installer for PVE 5.0 beta2 when selecting zfs raid1 from the menu it shows entire disk /dev/sda, any possibility to have the...

  13. Trim virtual drives

    Hey everyone ! We were moving disks from a storage to another and noticed that when they arrive on the new storage, the thin provisioning expanded to full space. Before, when we had a few VMs, we could use the old method to empty the disks (using dd to fill the disk with zeros and deleting...
