This alarm presents the percentage of used inodes storage of a particular disk.
The number of inodes indicates the number of files and folders you have. An inode is a data structure, containing metadata about a file. All filenames are internally mapped to respective inode numbers, so if you have a
lot of files, it means there are a lot of inodes.
If the alarm is raised, it means that your storage device is running out of inode space. Each disk has a particular limitation on the amount of inodes it can store, determined by its size.
Many modern filesystems use dynamically allocated inodes instead of a static table. These should not be presented on the charts associated with this alarm, and should not ever trigger it. If such a filesystem does trigger this alarm, and it's constantly reporting max inode usage, it's probably a bug in the filesystem driver. Some such filesystems incorrectly report having max inode count when they should not because they have no max limit, and in turn they trigger a false positive alarm.
Clear cache files or delete unnecessary files and folders
inodes you store currently, you can clear your cache, trash any unnecessary files and folders in your system.We strongly suggest that you practice a high degree of caution when cleaning up drives, and removing files, make sure that you are certain that you delete only unnecessary files.
