new ZFS - new disk space - how to add to install virtual machines

[Miroza]

I have the proxmox system installed on a 64GB disk,
now I have installed 3 additional 4TB drives and made ZFS from them, how to add a new ZFS to the space where I can install virtual machines

root@debian-mt:/home/miroza# zpool status
pool: RAID
state: ONLINE
scan: none requested
config:

NAME STATE READ WRITE CKSUM
RAID ONLINE 0 0 0
raidz1-0 ONLINE 0 0 0

If you haven't done so, you need to add a storage with the pool as backend. In the GUI under Datacenter (left tree view) -> Storage.

Please be aware of this issue https://forum.proxmox.com/threads/zfs-counts-double-the-space.71536/#post-320919 with any RAIDZ pool. At this stage you can still destroy it and create it with a different layout if you want.

what is the best solution for a small business, there will be 3 virtual windows 10, file server etc.

In general, using mirror vdevs will give you the best IO performance and will not have that problem with unexpected parity data taking up space.
So a 4 disk RAID10 layout (2 mirror vdevs) would be okay for a start.

A general "will work for all" recommendation cannot be given. There are too many places in the design of the pool where you can tweak the performance (ZIL, special device, ...).

Looking closer at the disks in use I very much recommend that you get rid of those. These are SMR drives ( https://blog.westerndigital.com/wd-red-nas-drives/ ) which will be terribly slow and can cause the pool to fail because they are too slow and thus, it can happen that the kernel considers them as failed. If you haven't heard about all this (happened a few months ago) google "wd red smr".

Also, adding faster disks (higher RPM) will help the performance.

SMR drives
thanks for your help, my supplier agreed to exchange for another model,
but you still haven't told me what solution to give for 3 x 4TB for small company
