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 `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. + +### Useful resources + +[Linux Inodes](https://www.javatpoint.com/linux-inodes) +[Understanding UNIX / Linux filesystem Inodes](https://www.cyberciti.biz/tips/understanding-unixlinux-filesystem-inodes.html)
