NOOB question about storage

[sagiaccotto]

Hi, I've installed Proxomox on a Hp Proliant Micropserver gen8 with 4 hdd's. During setup I've chosen to install Proxmox on these drivers with ZFS RaidZ configuration. Maybe this was not a good idea. Not sure yet.
Now I've installed a Debian client LXC container with security cam software. The images of the camera's should be witten to this ZFS RaidZ config,
Now the question: what do I have to do to make the space on the 4 disks available as storage for the debian client? Everytime when I want to make some kind of storage (Directory, LVM, ZFS, I don't know), it tells me there are no disks available because they are all used for the ZFS RaidZ.

My personal statement regarding this: https://forum.proxmox.com/threads/fabu-can-i-use-zfs-raidz-for-my-vms.159923/

Thanks people! I assume I can't change to "striped mirrors" without a complete new installation?

Seems so...

You can NOT change the topology of a vdev "on-the-fly". And while you could add mirrored vdevs, you can NOT remove that RaidZ1 vdev after doing so. So yeah, you need to destroy the pool and then re-create it. Reinstalling is the easiest approach.

This is a good time to test the backup/restore strategy...

It's my first time running Proxmox (comming from Esxi), so nothing important yet on the machine. Will install it from scratch. Thanx for you help!
