good day in Ethiopia ;-)
in case you have good RAID controller
i will do the following

1. boot to RAID controller manager and configure
    3 hdd = RAID5
    2 hdd = RAID1
    1 hdd GlobalHotSpare
2. boot to ISO proxmox and install
    ZFS over that raid5 (use whole space)
3. create filesystem 'backup' over that raid1 (mirror)
    e.g ext4 in LVM2
4. add filesystem 'backup' to proxmox storage
5. nagios and mailserver may be created in CTs (containers)

hope you will have 2nd server and be able to create proxmox cluster
in near future. After that you will see great advantage of rapid ZFS
good luck

Personnaly, I would do a Raid 10 with all the disk (3*2, ~900 Go of 
storage). Better performance and security, and install Proxmox on the 
whole volume.

I would not backup on the same server.

Note that it is not very secure to use only one server for all, and for 
example for mail server, which is quite critical. It would be better to 
have a real cluster with at least three nodes... Power Edge R730 is 
relativey old, is it still under maintenance from Dell ?

My two cents...

Mix RAID and ZFS is not a good idea, ZFS needs to deal directly with disk.

My advice is to install Proxmox in a RAID-1 and then use the other
disks with RAID-5 as a VM storage (LVM-Thin for instance, or even
XFS). In this way, the VMS will be safe in the 2d arrangement.



Best regards

Re: [PVE-User] Fw: Proxmox

[Gilberto Ferreira]

Hi again...

I think it is better if you started with the Docs... Proxmox is a very
well documented project.
Start here:

Backup and restore: https://pve.proxmox.com/pve-docs/chapter-vzdump.html
(and check this too: https://pbs.proxmox.com/wiki/index.php/Main_Page)
Cluster: https://pve.proxmox.com/pve-docs/chapter-pvecm.html
High Availability: https://pve.proxmox.com/pve-docs/chapter-ha-manager.html
