Projects / Shake


Shake is a defragmenter that runs in user-space while the system is in use (for now, on GNU/Linux only), without the need to patch the kernel, and without the need to patch the kernel. Unlike xfs_fsr, it only uses functions common to all filesystems. It aims to evaluate the cost of fragmentation based on criteria such as fragment number, distance from "friends" (by default, a group of files used at the same time), file age (rewriting old files allow the filesystem to reclaim free space), file size, and number of "crumbs" (very small fragments that force the head to move repetetively). A Python module that parses the output of the verbose mode is included.
