Virtual machine Ram problem

Yes, never use ZFS with RAID controllers, only with HBA.

very clear, ok i will follow your advice

LVM is very mature and light on ressources which is a requirement in this scenario.
If you have a larger machine where you have some spare RAM, give ZFS a go. It's resilency is great but it needs to communicate directly with the devices (that's why a RAID controller is not suitable). Also, ZFS features zvols (virtual disks) which are also very convenient to use with proxmox.
That all comes to the expense of RAM.

Many customers use SANs, even there, you would use LVM with proxmox to have access to the LUNs from all nodes at the same time (ZFS would not work there).

very exhaustive.
In fact, in lan I have a nas and I could use it just like you say, as I already do elsewhere.

You can use iSCSI, SMB/CIFS, NFS, etc. - plenty options to choose from.
It depends on what you want to do. If you want to use it for backups, NFS/SMB works perfectly fine.

thanks, then i will create array with raid controller and reinstall proxmox in lvm
