Disk defragmentation is an operation that we often use when we use a computer, defragmenting the disk regularly, allowing our computers to run faster. In the Win7 system, the system defaults to the disk defragmentation plan, and some users do not want to follow the system's default settings to organize, what to do?
To set the method:
1. Click "Start"-"All Programs"-"Accessories"-"System Tools"-"Disk Def
If you're a Linux user, you might have heard that you don't need to defragment your Linux filesystem. You may also notice that the Linux distribution does not have a disk defragmentation tool attached to it. Why is that? Want to know why in normal use, the Linux file system does not need to defragment, and Windows wants to. You need to understand why fragments are generated, and how Linux and Windows two file systems work separately.

What if the hard drive doesn't finish the defragmentation?
Workaround One:
Defragment the hard disk in the system, and start again if a write hard drive and some background programs start. Before defragmenting the hard disk, disable the screen saver, set the system to wait, turn off the hard drive to never, and check to see if other programs are running and shutting down in the system background. If the LAN is connected, it is best to pull it

Defragmentation of disk under LinuxSome posts on the web say that XFS does not need to be defragmented, but it is wrong. XFS, such as delayed write technology, can actually reduce fragmentation, but if the server is in use for several years, and the file operation is more frequent, it will be fragmented and should be sorted. Note: The XFS-related commands in Debian are in the Xfsprogs package, and the XFS_FSR command is in the Xfsdump package. So to u

that exist in the index to reduce the internal fragmentation by compressing the rows in the index page and then deleting the unwanted pages that are generated. It does not experience blocking problems but it does not result in several other methods altogether. This is because DBCC INDEXDEFRAG skips the locked page and does not use any new pages to reorder the indexes. If the number of fragments in the index is large, you may find that DBCC INDEXDEFRAG takes longer than rebuilding the index. DBC
