Coming from a Windows environment I'm used to performing regular defragmentation on FAT32 and NTFS partitions. Do I need to defragment EXT2 partitions in the same way? And if so, which tools do people use?
I have always heard that you do not need to defragment Linux. http://www.linux.com/howtos/Partition/formating.shtml http://www.linuxgazette.com/issue55/florido.html http://www.linux-mag.com/2002-10/jfs_01.html http://wiki.arslinux.com/About_Defragmentation : "Why? Because the Linux filesystem, ext2fs, is designed to be much less prone to file fragmentation than the Windows filesystems, FAT32 and NTFS. As it decides where to put a file, it does small-scale rearranging wherever it can to prevent file fragmentation. Usually this is successful enough that you never need to "defrag" an ext2 partition. However, sometimes, such as when you run an ext2 filesystem for a long period of time at 85% or more of its maximum storage capacity, this will begin to break down. There are ext2 defragmenters available, but it's generally considered good practice to avoid this by simply keeping a margin of free space on your ext2 partitions." -- The Mailing List for the Devon & Cornwall LUG Mail majordomo@xxxxxxxxxxxxx with "unsubscribe list" in the message body to unsubscribe.
