Good evening,
I recall that a few years ago, I somehow checked my Fedora system for disk fragmentation. I also think the tool came with Fedora; i did not have to install it separately. Now, I don't recall the name of the tool that did that. Nor can I find any tool to do that. How do I check my F-28 system for disk fragmentation?
thanks, Bill.

Hi Bill,
I don't know of any defragmentation tool. Are you maybe thinking of "fsck"? It's a program to check the health of the filesystem and recover any lost bits, etc.

No. It was definitely a tool that included fragmentation checking and defragmentation functionality.
You could be thinking of e4defrag?

There was a program called "e2defrag", but it was for ext2 only. e2fsck will give you a fragmentation percent at the end. Just don't forget the "-n" unless the partition is not mounted!

I saw this after tagging the thread "SOLVED". But for continuing education, I'll give this a try tomorrow morning.
Thank-you, Samuel. Bill.

This does raise a few questions, but I'll deal with those late this month, in a separate thread, after I upgrade to F-29.
Thank-you, Samuel. Bill.

You don't. The ext2/3/4 file systems are designed to minimize fragmentation, and one of the worst things you can do is defrag your system because that will just cause constant fragmentation. In fact, the best way to defrag if you really really have to is by backing up, reformatting and restoring your system.

Not what I expected. But I like it!
Recently, I've been moving a lot of files and sub-directories around. And I'm preparing for a semi-annual big back-up and system upgrade (to F-29). Because it has been a few years since I last checked for fragmentation, I thought it would be good to at least check.
A few minutes ago, based on Ed's reply, I tried "e4defrag -c" on "/home": ----- e4defrag 1.44.2 (14-May-2018) <Fragmented files> now/best size/ext 1. [user1's home]/.ICEauthority 30/1 4 KB 2.

The results above do raise a question in my mind: What are those "[user's home]/.local/share/tracker/tracker-miner-fs.log" files? Anything to do with coin or data mining, or something else malicious?
Thank-you, Joe and Ed. Bill.

These are produced by the "tracker" packages.
I, personally, couldn't find a need for them so I erased them quite some time ago.
Do a "dnf info tracker" and "dnf info traker-miners" for more info on what they do.

I assume you deleted the files, not the packages. Mine were dated 2013, so I deleted them.

That gave me a rough idea. Doesn't sound like anything I have wanted or do want. But I can't predict the future, so I'm keeping the packages.
Thank-you, Ed. Bill.

I should have been specific.
I did do "dnf erase tracker*" as it was an easier way to ensure the daemons wouldn't run for any user.

Tracker is a service that indexes your files so you can easily search for them by name and content.

I really do not see any need to defrag a Linux system. The file system itself already takes care of everything.
