No, it's about files that simply exist.

As you add files to a disk, it fills up, it's that simple.  Once there's no space left, no more can be added, and most cannot be written to, because a write usually means adding data (even when it's a replace - the data is usually added, then the old data removed)

There are two ways to "fill" most types of Linux disks  - by size of data and size of the index needed to find files.

Try running

df -hki

This will report on the size of your files AND your inodes.  If either is full on a disk, it will tell you that the usage is 100%

Since it is an on-Premise instance, your server administrator will have to do the cleanup. Hard to know the files to be cleaned up without knowing what is in your folders.

Do you need anything from my end let me know i will share 

[Jobin Kuruvilla [Adaptavist]]

Sorry, I should have made it clear. You need to work with your sys admin to make space. I was suggesting that this is the wrong place for a request like this.

I can understand that is there any open files will occupy root file system in confluence ?
