does a Linux filesystem know fragmentation ? 1

[rene1000]

Hi,

Can anyone tell me if a harddisk with a linux filesystem knows fragmentation, and if so, are there any defragmentation applications available ?

Thanks in advance

Don't believe an ext2 or ext3 file system will fragment. Files are built with inodes and indirection, and thus having sequential blocks contain pieces of the same file provides no performance gain.

While ext2 and ext3 will fragment, there isn't a noticeable performance loss. So, its pretty much a non-issue.

Yes, Linux filesystem got fragmentation.You can solve it with e2fsck (scandisk/Defrag)

You can try to turn off your linux machine without normal shutdown.
You can see more clearly which partition from linux got fragmentation.
Good Luck

e2fsck checks and repairs errors on ext2 partitions. It doesn't do an actual defrag, but it does rearrange data a bit. Linux filesystems do not become as fragmented as Windows filesystems do. I've never defragged a Linux partition before.

I did a search on Google and found this defrag utility. I've never used it, but you can give it a try if your concerned about your disk being fragmented.
