How do I get more inodes?
Do you want to increase the amount of inodes? Either increase the capacity of the disk entirely (Guide: Increase A VMware Disk Size (VMDK) LVM), or re-format the disk using mkfs. ext4 -i to manually overwrite the bytes-per-inode ratio.
How do you release inodes?
As I said, inodes belong to the file, not the directory entry. If a file has two directory entries linked to it, deleting one will not free the inode. Additionally, you can delete a directory entry but, if a running process still has the file open, the inode won’t be freed.

How does Debugfs work?
Debugfs exists as a simple way for kernel developers to make information available to user space. Unlike /proc, which is only meant for information about a process, or sysfs, which has strict one-value-per-file rules, debugfs has no rules at all. Developers can put any information they want there.
