| File system metadata test program is used to test i-node operations |
| with heavy workload. Make sure every i-node operation gets the |
| expected result. This script creates a lot of directory entries with |
| k-tree data structure. |
| |
| k-tree is a transformation of binary tree, For a binary tree, each father |
| node has 2 children at most; but for a k-tree, it can has k children. We |
| need to test both file and directory, so we do some changes for k-tree |
| concept here. viz. each father node has k sub directories and k text files. |
| |
| Note, test will caculate approximate disk space firstly based on the test |
| parameters from user. parameter tree_depth should be less than 10; |
| parameter node_number should be less than 20. If user passes a larger |
| number, it will generate a huge directory hierarchy, which might exhaust |
| your disk space soon. |
| |
| As a suggestion, it's better to run the script on a free partition, so |
| you can recover it easily by formatting disk after test gets finished! |
| |
| Here are the component list of fs-metadata test program. |
| k-tree-gen k-tree generator |
| k-tree-trav to modify a k-tree with i-nodes operations |
| k-thread.sh test thread |
| fs-metadata.sh the script to lauch test threads. |
