As you should already know, the possibilities in Linux are practically endless, and in the case of partition management it was not going to be less. There are both the possibilities that RAID offers us, as well as the famous LVM that we have already talked about many times, as well as a multitude of tools for creating and managing partitions such as Gparted. But today we come to talk about a slightly more unknown to some, and that is mhddfs.
Imagine that you want to combine several hard drives that you have installed on your computer so that they are only one directory. This is possible thanks to RAID and LVM, but also with this alternative that we offer you today. For this we will join them in a single virtual mount point, making the physical disks behave as a single unified storage system. Unlike the alternatives, mhddfs allows you to combine different systems like tmpfs, NFS, etc., into one.
Another advantage is that no need to format to create the new mount point, as in other cases. This way you will not have to make a backup copy and erase the information that is already on these disks. And what do you have to do to be able to use this very practical tool? Well, the first thing is to install it in our distribution through the mhddfs package that will surely be available in the repositories of your favorite distro. We can then access your manual for further help.
If you liked this management tool for your partitions, I recommend that you also take a look at other "unknown" to many, such as mergerfs, which is also available for Linux, as well as greyhole. The first will allow you to manage your partitions with different file systems to manage them in a simpler way and the second is another application that will allow you to work with storage media, only in this case oriented to Samba.
