I got to know now that I cannot add disks to zfs pool but can create new pool only right?

It is new server which have no data, I can do reinstall. I am confused how proxmox store data when creating VM My understanding is: create meta data on local zfs (first pool created with proxmox installation) => I think that will affect VM speed create VM disk in selected pool (second or third)...

Yes I created second and third using GUI I can use them only for VM disks but cannot store iso, templates or bacups on them as on local storage Is it ok to install proxmox in HDD then can use them for backups, iso and templates insted the existing first pool which is NVMe? will it affect the VM...

I have installed proxmox in zfs raid mirror 2 x 250GB NVMe => first pool I have created second zfs pool as raid mirror 2 x 1.6 TB SSD => second pool I have created third zfs pool as raidz1 4 x 2.4 TB HDD ==== => third pool

To use replication I think you have to use ZFS or BTRFS

I have installed proxmox in zfs raid mirror 2 x 250GB NVMe => first pool I have created second zfs pool as raid mirror 2 x 1.6 TB SSD => second pool I have created third zfs pool as raidz1 4 x 2.4 TB HDD ==== => third pool now proxmox use only the first pool as storage for metadata, iso...

I would to share this article comparing benchmark for ZFS X LVM X LVM thin x BTRFS https://www.assyoma.it/single-post/2015/02/02/zfs-btrfs-xfs-ext4-and-lvm-with-kvm-a-storage-performance-comparison

Is it possible to add new disks to the existing pools without building the arrays? if yes, how?

what is GDPR compliant

I think the new SDN is useful to create zone and allow VMs from different nodes to connect to each other over local area networks. i looks like creating virtual switches on the data-center level my goal is to prevent virtual machines on the same node to connect to each other to avoid any...

In this case I can mix all sizes and types of disks right? I mean it will not matter HDD, SSD, I will select raid 0 btrfs while installations,right?

so, you recommend BTRFS with RAI0 based on your previous experience, right?

Not raid 1 which will consum ram and cpu but I am afraid zfs may do Please note I buy hardware from dell themselves

No problem with RAID 1 BUT I want to avoid CPU and RAM high usage and save these resources for high density virtualization. as I understand from you is that I use NVMe and SSD for metadata and mount storage in HDD but how can I arrange like that?

You are right, but I bought it new assembled with excellent price. I want to for client to buy c/m and use it as they want They may use it for storage or databases or stream …etc Nowadays dell gives option to separate operating system on NVMe with raid they call it boss and other disks with or...

because of different sizes and types of disks, I am afraid of BTRFS lower speed to speed of HDD so what I am thinking is to use raid controller for only operating system with ext4. And then use SSD for BTRFS or zfs and then HDD for BTRFs. Do you think using BTRFS on different disk types is ok?

Great, thank you very much for all

So, I will use HDD as backups for SSD right? also for2 x 250 GB NVMe , I will use raid controller then I can get benefits of it, right?

Which file system do you use?

so, what is your suggestion for better installation
