Harddisk Format / Freenas via NFS

[bumann]

Hi,

i use a two node proxmox 5.1 setup with freenas( 0gbit / ZFS) NFS as storage.
I sync the freenas storage via Internet to a second freenas.
What do you think is the best setting for the Harddisk Tab.
Virtio Block and raw ? or something else?

Hi,

Virtio Block and raw ? or something else?

Raw is faster than qcow2, but qcow2 has more features like snapshots.
If you use qcow2 consider that you use ZFS what is also a copy on write system.

We recommend SCSI with a virtio bus as VM storage interface.
