All disks not visible in GUI

[dnd]

Hi,

I am using FreeNAS-9.10-STABLE-201606270534 (dd17351). When I go to Storage=>Volumes=> View Disks I see only 2 out of 4 disks which are attached using 2 separate 2 bay USB 3 enclosures and each 2 bay enclosure in configured as JBOD. See attachments.

In the report view, I see reports for all 4 drives (da0 to da3) as expected (see attachments).

Zpool status shows all 4 disks (see below), so it this maybe a bug with GUI and should I file a bug report?
I have read about similar issue in version 9.3, but apparently that was fixed.

Feel free to submit a bug report. Please also include the output of "camcontrol devlist".

Do note that we strongly discourage the attachment of storage via USB. It obscures the ability of the system to identify problems developing via SMART, and over the years has been shown to be relatively unreliable due to the externality of the drives, which may be inadvertently detached, or a crummy bridge chip might flake out and cause read issues, etc. USB pools often don't end well.

USB enclosures do strange things, they are not meant to be used with NAS devices.

I want to add my voice to that as well. We VERY VOCIFEROUSLY advise against running a ZFS pool through a USB bridge of any kind. You are POSITIVELY GUARANTEED, with probability 100%, to run into serious issues.
