How to Add a New Location on Rocky Linux?

Dear BMD Forum,

I have a seemingly simple question,

How can I add a new location in DVR 20 on Rocky Linux to where my Media resides?

OR, more specifically,

Where within the Rocky Linux tree does my 2nd (or 3rd) Separate hard disk (Media) drive(s) reside, to be able to point DVR to that location?

I already know, that on the Media Page (tab), I can Right Click on a blank space in the Media Storage Location, and simply choose the only option there, namely, to Add New Location - but then I'm baffled as to where my 2nd or 3rd Separate Hard Disk Drive(s) resides within the presented Linux File Structure (Tree)! Can anybody help me out?

How to identify my 2nd (or 3rd) Hard Disk(s) in Rocky Linux within the presented menu, after having clicked 'Add New Location'? My guessing is, it would be OUTSIDE of 'Home', 'somewhere within the root'....

Thank you very much for your help! I know a little bit 'Rocky Linux', but am by long not a Linux expert....

Warm regards from Victor.

On most Linux systems there is a folder called /mnt or /media, where the os auto mounts the drives.

Thank you, Christoph! I'll have a look there.
I myself have been looking at /dev, but I guess that must be off, then?

Have a great day!

Best from Victor.

You are not wrong with that assumption - you can find your harddrive in the /dev directory.
The /dev directory consists of files that represent devices that are attached to the local system. However, these are not regular files that a user can read and write to.
If you for example want to format a drive with gparted you need to know the device path like /dev/vme0n1p2 or /dev/sda.... But the filesystem on that drive is mounted to /mnt or /media (by default).

Thank you so much, that is so helpful!

I'm currently not on my computer, but will have a look by tomorrow.

Have a great evening!

Warm regards from Victor.

'somewhere within the root'....

That is a good guess, if only because everything is within root. On Windows, the file system is organized around physical devices, like C:\, D:\ etc. On Linux, all the physical devices appear under the filesystem root / .

If you run this command in a terminal window as root,

Code: Select all

 df -h

you will see output like:

Code: Select all

Filesystem      Size  Used Avail Use% Mounted on
tmpfs           3.2G  1.9M  3.2G   1% /run
tmpfs            16G  157M   16G   1% /dev/shm
/dev/sda1        60G   52G  5.4G  91% /
/dev/sda2      1007G  613G  343G  65% /home
/dev/sdb1       235G  147G   76G  66% /projects
/dev/sdc1       1.7T  1.6T   24G  99% /archives


The lines we care about are the ones that start with /dev/sd* . On (most?) Linux, the fixed drives are named /dev/sda, /dev/sdb, etc. Partitions on a disk are numbered. So /dev/sda1 is the first partion on /dev/sda.

The last column in the output is where the device is mounted in the / tree. In the example, the files on /dev/sda1 will appear under /, the files on /dev/sda2 will appear in /home, and /dev/sdb1 is mounted on /projects. Removable disks are usually mounted on /mnt or /media, as Christoph mentioned.

Thank you, Stephen, for your kind and elaborate answer!
That's most helpful, I'll have a look later on (it's crack o' dawn over here).

My internal, though separate, hard disk contains only (very important) video-data, and resides 'somewhere outside of /home'. I want to be able to permanently address it from within DVR.

Warm regards,

Victor.
