Understand the alert
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.
Troubleshoot the alert
Clear cache files or delete unnecessary files and folders
- To reduce the amount of how many
inodesyou 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.
