telling the driver to remove it and then add it back.
How did you do that? Did it involve physically pulling and reinserting
the drive?
Somehow I ended up in /sys/bus/pci/drivers/ehci-pci, but in your case it
might need to be /sys/bus/pci/drivers/xhci-pci since you're dealing with
a USB 3 device. In there are links to the USB pci devices that are
managed by this driver. From the logs you included, it would be
"0000:00:14.0" in your case. Doing "echo 0000:00:14.0 > unbind" will
disconnect the entire usb bus on that device and "echo 0000:00:14.0 >
bind" will re-initialize it.
(Note the message from mdadm. The RAID array has /dev/sdd and /dev/sde,
but, again, RAID has already been stopped before running udisksctl.)
I really have my doubts about that. Something definitely still has the
drives open at this point. How did you stop it?
