Logical partition invisible in Caja? [Solved]

[Mr Mate]

Hi everybody,

I have placed my personal data files in a logical partition, following this guide https://www.maketecheasier.com/move-home-folder-ubuntu/, but it confuses me that this logical partition isn't shown in the file manager (Caja) at the top level:

As you can see, it only shows the file system partition and another primary partition (23 GB), and of course external drives ("Hitachi" is an external harddisk). To find the logical partition with my personal folders I have to open first the file system folder ("/") and then the "home" folder. So intuitively, one would think that my personal folders in the logical partition were still in the "/" partition Is this just me, or is it Caja that has a funny structure?

My username folder is shown at the desktop, but not the personal folders I later placed in the logical partition, after following the mentioned guide. Now I see that I can only copy-paste these folders to my desktop, not cut-paste them. Does that mean that if I copy-paste them, it's actually the folders I copy? Or is it just the icons?

Let's see the ouput from these commands.

Code: Select all

lsblk -f 
cat /etc/fstab

Here you are:

tl@tl-P5Q-SE ~ $ lsblk -f

The logical partition is sda6.

Must be just a foible of caja - same behaviour here.

[Mr Mate]

Yes it looks so. Thank you.

I've just found out that it's only the top folders at the logical partition I can't cut-paste, - the files and sub folders I can cut-paste without problem. Very good, but not obvious for new users of caja.

but it confuses me that this logical partition isn't shown in the file manager (Caja) at the top level:

That's perfectly normal. Think of a logical partition as a fake partition which doesn't have any data other than the partitions you see in the file-browser...so there's no reason to show the logical partition. (Plus it's supposed to be "transparent" - you don't see it - because it's a work-around to the 4 partition limit).

[Mr Mate]

Okay thanks, but I really don't understand. If the logical partition has no data, then where is that data (I thought) I put in it? Is it still in the primary OS partition?

[syg00]

That explanation was wrong - it applies more to extended partition. One of the primary partitions has to be converted to an extended partition - this is the container for logical partitions. Logical partitions do indeed hold filesystems.

[Mr Mate]

Okay, thank you.
