>Description:
Using a gmirror/gjournal filesystem on 2 external USB drives, the gmirror device is not detected during boot if the drives are connected prior to booting.
It should.
It is detected correctly if the USB drives are connected *after* the boot has completed (after "login" starts).
Configuration (when all is fine):

Trying to mount root from ufs:/dev/ad0s1a
At this point the system is up, the two "regular" UFS filesystems are mounted, but the device mirror/cxm has not been enabled:
# gmirror status
(no output)
When using "gmirror unload; gmirror load" nothing happens (i.e. no disk activity, no further dmesg output, no new devices)
After unmounting da0s2a and da1s2a and unplugging/replugging the drives to the system, dmesg reports the following additional messages:
umass1: at uhub3 port 4 (addr 3) disconnected

At this point the device mirror/cxm is ready to use and can be mounted successfully.
>How-To-Repeat:
1. configure a 2-way mirror on external USB drives
2. reboot the system while keeping the external drives connected (and externally powered)
observe: the gmirror is not detected upon system startup.
>Fix:
Disconnect and reconnect the USB drives.
