Hi,
I have temporarily connected a Raidsonic IB-3640SU3 to my FreeNAS 11.0-U4 via USB3. The Raidsonic box is a four-disk external USB enclosure without its own RAID capabilities and exports the four disks as four disks. The host system is an HPE Microserver Gen8 which has 4 SATA disks of its own.
On this hardware, Linux (grml) sees the disks from the Raidsonic box just fine and can use them. I have used this system to zero out the disks completely.
The Raidsonic box has the annoying habit of exporting all four disks with the same serial number:
This caused FreeNAS to act up. The (old) web interface just offers da2 in "View Disks", and the syslog is full of multipath messages. This can be googled for FreeBSD and the recommendation is to manually disable the geom_multipath kernel module in this case. I did that.
In dmesg, I see da2 to da5 just fine, but the web interface still only shows da2. I am also a bit confused that dmesg is full of unretryable errors regarding da0, which is one of the USB sticks the system runs from, without the webinterface showing obvious troubles with the system "disks".
I do not have too much clue about how FreeBSD handles its disks, and the FreeBSD people in my personal bubble don't either, so I'm asking here. I know my way around Linux and somer other Unices, and need some FreeBSD cookies to debug this. I'll happily give information that might be helpful. Attaching dmesg for starters.
