Fail to Boot from USB stick when a USB External HD attached at the same time - snowf0x - 10th May, 2013 11:01 PM
Hi All,
I had my PI boot up from a USB stick, i followed tutorial from this forum, everything works fine until i plugged my USB hard drive to storage torrent downloads.
It appears when Pi reboot with both USB stick and USB hard drive, it wont boot up. If I un-plug hard drive, it went fine as usual.
My guess is Pi confused about two usb device, and trying to boot up from the hard drive.
This is my cmdline.txt:
dwc_otg.fiq_fix_enable=1 sdhci-bcm2708.sync_after_dma=0 dwc_otg.lpm_enable=0 console=tty2 root=/dev/sda2 rootfstype=ext4 rootwait logo.nologo quiet loglevel=0 splash
What i do right now is unplug HDD when Pi reboot, and plug it back after it boot-up. But this way HDD get mount to different path everytime. Some time /media/usb2, some time /media/usb3, which screw up my symbolic links like /home/xbian/downloads, causing transmission problems.
Guys, how can i solve this problem?
P.S.
some command output i think maybe helpful

Does it help if you connect the USB stick to the other usb stick (so switch the hdd and the stick)?

you are probably accessing the usb attached devices via /media folder ?
can you please check the following:
1) attach drive
2) try to access the device via /var/run/usbmount
3) check with whatever process needed to change path under /media, but then check, if the names are preserved in /var/run/usbmount?
