Now it's a little clearer. ls /vmfs/devices/disks Doesn't show the usb disks at all. The question is can I temporarly stop usbarbitrator (like seen: http://www.virten.net/2016/11/usb-devices-as-vmfs-datastore-in-vsphere-esxi-6-5/ ) to be able to see the disk information and create a virtual RDM. And after enabling usbarbitrator or after an reboot is it still possible to access the vRDM. Have to check this.

The problem is that USB disks larger than 2TB can't be mounted as datastores. So I can't create an access with RDM.

Sorry my post has been written before I saw that you have updated your post. First a short question: If I'm using virtual disks on datastores and using them in XPenology with BTRFS - is it a good way? Because I'm using then two filesystems? VMFS and BTRFS? FreeNAS users told me that ZFS shouldn't be run like that, ZFS has to be on the baremetal disks and no layer should be between data and disk except ZFS. ZFS seems to be really critical because of RAM & disks and the latency of USB. So virtual disks (VMFS) and BTRFS are usable? There's no problem then using it with RAID? And BTRFs doesn't have a problem with USB disks and RAID?

Hi, I'm currently using vmWare ESXI 6.5 on an Intel NUC and I have two 3TB USB drives attached to the NUC. I first tried to use FreeNAS but the FreeNAS community really doesn't like the idea that I'm passing through two 3TB USB drives to FreeNAS and using it as a RAID1 with ZFS. So my question: Is it possible to use BTRFS (with a RAID1) with USB drives which are passed through directly to a virtual XPENOLOGY? The VMs and ESXI are installed on the internal msata ssd drive.
