|
|
|
* Don't plug in USB devices with a hub because there's no way to tell it which
|
|
|
|
|
is source and target - its the first drive detected (top port) that is the
|
2016-02-10 10:05:11 +01:00
|
|
|
source and the second (bottom port) is the target
|
2017-10-25 22:29:10 +02:00
|
|
|
* Don't turn it off without shutting down the system, when grooming is done it
|
2013-01-16 16:34:06 +01:00
|
|
|
shuts down automatically: losing power while it's running can trash the OS
|
|
|
|
|
on the SD cards because SD cards don't always like dirty shutdowns (ie power loss)
|
|
|
|
|
* Using a target usb stick that has a status light as long as the device has
|
|
|
|
|
power is a really useful thing as there the other status lights on the groomer
|
2017-10-25 22:29:10 +02:00
|
|
|
are less than indicative at times: because the 'OK' led on the RPi toggles on activity
|
2013-01-16 16:34:06 +01:00
|
|
|
it can be off for a long time while processing something and only comes back
|
|
|
|
|
on when that process finishes - hence why a USB that has some sort of LED activity
|
2016-02-10 10:05:11 +01:00
|
|
|
when just plugged in (even if not reading or writing but while the USB port is
|
2013-01-16 16:34:06 +01:00
|
|
|
powered) is helpful in determining when the process is finished - when
|
2016-02-10 10:05:11 +01:00
|
|
|
the rPI is shutdown, the USB port power is shut off and that LED will also
|
2013-01-16 16:34:06 +01:00
|
|
|
then be off on the USB device
|
|
|
|
|
* Use a larger target device as all zip files get unpacked and processed onto
|
|
|
|
|
the target
|

|
|
|
* If you have an hdmi monitor plugged in you can watch what's happening for about
|
2016-02-10 10:05:11 +01:00
|
|
|
30 minutes until the rPI's power saving kicks in and turns off the monitor
|
2017-10-25 22:29:10 +02:00
|
|
|
* If only one usb stick is present at power up, it doesn't groom and looks like
|
2013-01-16 16:34:06 +01:00
|
|
|
a normal rPi
|
2017-10-25 22:29:10 +02:00
|
|
|
* If you want to ssh into the RPi username is 'pi' password 'raspberry' as per defaults

USB Ports
|
|
|
|
|
=========
|
|
|
|
|
|
|
|
|
|
If you connect multiple keys to the RPi, they will be detected in this order:
|
|
|
|
|
|
|
|
|
|
First: Top left
|
|
|
|
|
Second: Top right
|
|
|
|
|
Third: Bottom left
|
|
|
|
|
Forth: Bottom right
|
|
|
|
|
|
|
|
|
|
* As long as the source key (sda) is connected to the top left port, the
|
|
|
|
|
destination (sdb) can be connected on any other port.
