Cool, welcome to FreeBSD then!  A good starting point, if you haven't
already discovered it, is our docs collection at:

http://www.FreeBSD.org/docs.html

Happy FreeBSD'ing :)

 Hi,
 
 How can I defragment my HDD partitions in FreeBSD?

You don't need to.   The FreeBSD file systems don't have a problem
with fragmentation.If you run fsck and see the word fragments, it
means something other than in the MS world.

But, if you insist on doing it, your best bet would be to use
dump(8) to make a complete backup of the filesystem.  Then
re-newfs(8) it and then restore(8) the backup in to it.

FBSD partitions do not need degframenting.
The native UFS does a great job of allocating
space.

You mean you just escaped from MS alter-world that is striving
to disolve the real world.   Congradulations!

Re: Disk defragmentation

2004-01-07 Thread Michael A. Smith
 How can I defragment my HDD partitions in FreeBSD?

As I understand it, instead of writing instantly to disk (breaking 
things up to do so, a la Windows), FreeBSD (and Linux, Solaris, etc...) 
caches disk writes until a proper place on the disk can be found.

This is why it can be disastrous to just shut off a FreeBSD system (i.e. 
pull the plug). A proper shutdown insures all the not-yet-written things 
get written to disk.

Welcome to the brave new world of FreeBSD. Cheers!
