I'm using raspbian debian wheezy. I automatically mount USB drives using usbmount. I mount FAT usb drives with the flush option. Now I was wondering. When I shutdown my pi, does it perform the umount command on all the drives? And does it also perform a sync before unmounting to write the buffers to the usb dirve?
I'm asking this because I couldn't find it and I really don't want to loose any data. Thanks in advance
Okay thank you, but what is the difference between pumount and umount, I thought the pumount does a sync before unmmounting and the umount doesn't. – user3673517 – 2014-08-28T11:21:43.270
I googled it and seems like pumount is just umount for non-superusers. – user3673517 – 2014-08-28T11:38:36.577
