Disk space != inodes. You asked about inodes. File systems have a
maximum number of inodes, the maximum number of files directories,
links, etc. that they know how to count for that filesystem at the
time the filesystem is built. Storing information about files takes
space on a filesystem, sot it's notrmally pre-allocated when making
the filesystem. From your own description, you've run out of inodes
and need to free some up, or rebuild your environment to better handle
structures that handle many small files.

It's one of the files in those directories.

Please stop confusing "inode" with "disk space" It's more like you've
run out of boxes to put things in, i.e. inodes, than running out of
space to store store the boxes (i.e., disk space).
