Mount external hard drive's folder as partition visible in df


Hello there,

I have an external drive which I mounted on /drive
in /drive I have 2 folders: Folder1 and Folder2

I'd like to somehow mount those 2 folders in root so they both can be accessed by /Folder1 and /Folder2 instead of the current /drive/Folder1

But the special thing in that request, is that both /Folder1 and /Folder2 would need to appear when I do the df command, a simple symbolic link is not enough for my needs (Amanda DLE's)

Thank You

OK first of all you don't mount partition on / instead use /media or /mnt.. i don't know if you can mount folders that easily..

yes I know the 'proper' way to mount, but for this purpose I need it to have the shortest path possible.
/Folder1
instead of
/mnt/disk1/Folder1

why don't you just create a hardlink?

Are Folder1 and Folder2 the mountpoints of 2 separate partitions, or are they subdirectories of a filesystem mounted at /drive?

If the former, just put appropriate entries in your fstab. If the latter, df can't look at them separately - it can only report free space on a filesystem as a whole.

PS hardlinks can't be made across different filesystems

And hardlinks are forbidden for directories.

I'd say use the bind option of mount. It alows you to mount any folder wherever you like, even if it is on a file-system that is already mounted.

mount --bind olddir newdir

Why don't we take a step back and ask what exactly you are trying to achieve and why. In other words, rather than asking a question about how you are trying to do something, let's get back to asking a question about what your purpose and reasoning is.

Since you are on Linux, using Amanda, I presume you are using gnutar for your backups. DLE's using gnutar don't need to be partitions. If you are using dump on Linux, don't.

From the Amanda FAQ: "A DLE refers to one entry in the disklist of an Amanda-configuration. General usage was to describe them as partitions, or file systems. But in fact they do not have to be either. They can be directory trees, or multiple trees, or trees with some branches cut off. So the more generic term DLE was coined."

You could create symbolic links to the subdirectories:
E.G.:
sudo ln -s /mnt/hpmedia/Documents/pdfdoc /pdfdoc
sudo ln -s /mnt/hpmedia/Documents/webarchives /webarchives

The links will be broken when /mnt/hpmedia/Documents is not mounted, but will be OK when it is mounted.
