Managing filesystem inodes

摘要

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.

1. A method, in a data processing system, for managing filesystem inodes, the method comprising:
monitoring inode consumption in a filesystem; periodically determining a number of inodes to add to the filesystem based on the Mode consumption; and adding the number of inodes to the filesystem, wherein periodically determining the number of inodes to add to the filesystem comprises, responsive to expiration of a tracking period:
calculating a rate of consumption of inodes over the tracking period;calculating a projected number of inodes at full workload;responsive to an expected inode consumption over a predetermined time period being greater than a number of available inodes, calculating a projected change;setting the number of inodes to add to the filesystem equal to a greater of the rate of consumption times a first time period or a maximum rate of consumption times a second time period; andresponsive to the number of inodes to add to the filesystem plus the number of available inodes being greater than the projected number of inodes at full workload, setting the number of inodes to add to the filesystem equal to the projected change; and responsive to the number of inodes to add to the filesystem being less than a floor threshold, setting the number of inodes to add to the filesystem equal to the floor threshold.
