How could I safely remove a USB drive attached on the fly to my Linux system?
umount does work. In fact, there is no error message at all, but the
flash drive still keeps blinking -- and it doesnt seem safe to remove
the drive yet.
I'm running SuSE 9.1, which mounts it under /media
As root
umount /media/usb*
works
/etc/mtab shows a ubsfs mounted filesystem in /proc/sys/usb
umount /proc/sys/usb
works as well
It's just that the Flash drive still keeps blinking. I would suppose
that that is the default behaviour of a usb drive -- it probably needs
to be "stopped" at a lower hardware level, rather than just
unmounting.
you don't want to unmount the usbfs system, as that is the pseudo-fs
that controls the USB bus itself.. Theoretically, simply unmounting
/media/usb* should work, but be aware, that syncing can take some time
(up to 3 or minutes with a large [i.e. > 128Mb] USB 1.0 disk) and mount
may not be acting in a synchronous manner. Try the following as root
sync
umount /media/usb*
