    How does using ZFS to mirror PVE (and nothing else) impact separate disks (for VM and container storage) that also use ZFS?

    I have some filesystem questions regarding PVE, ZFS and how they interact with VMs. The storage system I'm trying to achieve consists of 5 physical disks: Physical Disk Purpose RAID Disk 1 + Disk 2 PVE + mirror ZFS mirror Disk 3 + Disk 4 VMs and container storage a mix of striping and...

    Usable drive space to small and shows different sizes in each menu

    Hello, I got 3 Drives, each 279GiB installed as a raidz1. So the usable drive space should be ~558GiB (2x278GiB), but I am only able to use around 393 GiB. If I look at Storage -> My Storage -> Summary, then I can see that I am using almost 100% of the storage space, but there it says 536...
