Mageia forum

{I must be getting too old. The answer to this question should be obvious, but I cannot see it.}

I am running a standard installation of Mageia 9. It has the usual top-level "/" directory containing only the main folders. iT is normally a few GB but is only 14 MB.

But that isn't my problem. Every file in each of those subdirectories, including /home, is counted as being in /, which fills up very quickly. This seems to be a natural consequence of the directory structure, but it has worked that way for years. What am I missing?

Some more information would be necessary. How do you measure the size for / ? How do you check if a file/subdirectory is located in / filesystem ?
The output of

Code: Select all

df -PhT

would be helpful

df -PhT:
The size of / is the same. /dev/sdc is a USB key.

Code: Select all

Seems you missed one question.

Apart from that your / and /home is 100% full. Not sure you you cam to that 14 MB but / is currently 46GB in size.
On an unrelated note, any particular reason why you have separate filesystems for /usr, /tmp and /var ?

I still can't give a mechanism for this, but I cansee now why it happened when it did. A few months ago, I bought and added to my machine a drive in M.2 format to hold backups. In the M.2 format, it was a rather tiny PCB rather like a stick of RAM. Ther is a place on the motherboard to mount it physically. Because there were no cables involved, I had to accept thed rive letter the BIOS gave it, which was /dev/sda. Both Windows and Linux saw it as the first drive, and that was where Mageia installer put the installation, noton thje hard drive, which was now /dev/sdb That caused the confusion. I eventually forced the installer to use the original partitions on the hard disk, and it all came together
Sho mark this thread as SOLVED or INVALID, following Bugzilla classification?

Just mark it as DONE as there is no real solution.

Hint: you can use lsblk to more easily see the disk/partition hierarchy including the filesystem mounts.
