Abstract
A mechanism is provided in a data processing system for managing filesystem inodes. The mechanism monitors inode consumption in a filesystem. The mechanism periodically determines a number of inodes to add to the filesystem based on the inode consumption and adds the number of inodes to the filesystem.
Claims19
A method, in a data processing system, for managing filesystem inodes, the method comprising:
- monitoring inode consumption in a filesystem;
- responsive to expiration of a tracking period and responsive to an expected inode consumption over a predetermined time period being greater than a number of available inodes, calculating a projected change;
- setting a number of inodes to add to the filesystem equal to a greater of a rate of consumption over the tracking period times a first time period or a maximum rate of consumption times a second time period;
- responsive to the number of inodes to add to the filesystem plus the number of available inodes being greater than a projected number of inodes at full workload, setting the number of inodes to add to the filesystem equal to the projected change;
- and
- adding the number of inodes to the filesystem.
