In brief: Is there is anyway to trigger the same automount mechanism, that X appears to use, on unmounted USB drives that are already connected?
Background: I've got a C6 server with default desktop GUI installed for the sake of the onsite admin. There is a bash script I wrote that runs every night checking for specific folders on any drive and dumps data into it.
To ensure fs integrity, I do an unmount in the script when it's done in case anybody simply yanks the drive out without doing the proper process.
Now due to that, I would need to remount the drive when the script runs if it wasn't unplugged and replugged to trigger the automount.
Problem is, it is not certain that the same drive will be used so I cannot simply hard code a line that just do a mount -t ntfs-3g /dev/sde1 /media/backup. I cannot assume it would always be say /dev/sde1 or /dev/sdf2 as that depends on how many drives are connected before that and how was that particular drive partitioned.
The inbuilt auto mount mechanism also appears to use different mountpoints for different USB drives (based on drive label?) and so the best way for me is to force all USB drives to be remounted, and scan through the /media folder as that is where the automount mounts the partitions.
I could try to mount all drives found in /proc/partitions but that seems very dangerous since the list includes md partitions and array members.
So the question is whether there is anyway to trigger the same automount mechanism, that X appears to use, on any unmounted USB drives?
Trying resources I found online, It doesn't seem to be autofs or gnome-mount mechanism as neither of these are installed on the server. Both automount and gnome-mount command not found.

Emmanuel,
You can use the UUID instead of the device name

I thought of doing that but that assumes the same devices are used all the time. Otherwise, I would have to maintain a list of UUIDs to add every time and to keep trying every time the script is run which doesn't sound very efficient to me. Thus it seems to me like there should be a better way to do this especially since the mechanism already appears to exist.

Perhaps, this article maybe of interest.
