我在debian里找到的,不过它好像只提到以下一些文件系统。ext3是不是不需要?
defrag - ext2, minix and xiafs filesystem defragmenter
As a file system is used, data tends to become more and more scattered across the disk, degrading performance. A disk
defragmenter simply re-organises the data on the disk, so that individual files occupy a single sequential set of disk blocks,
and all the free space on the disk is collected together in a single region. This generally means that reading a whole file is
faster, and disk accesses in general are more efficient. |
