Defragmenting...
collapsed inline media
Man, I used to LOVE defragmenting drives. I felt like I was actually doing something productive, and I just got to sit back and watch the magic happen.
Now I know better.
I've never had to defragment the ext4 drives in my server. Ext4 is fairly resistant to fragmentation.
It's not really Ext4 doing that, it's a bunch of tricks in the OS layer and the way apps write files to storage that limits it.
You'll see it if you use something like a BT client without pre-allocation, those files can get heavily fragmented depending on the download speed.
One of the worst things that the newer Windows versions did is get rid of that little view of defragmenting. It was much more interesting than watching a number slowly tick up.
