No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

update 2: The Linux community has suggested that I use a tar file to backup, as this preserves symlinks. With that, the home directory now takes up just 290 ish GiB, as it should. Now I will be distro hopping, wish me luck!

update: I was able to copy it! There are still some folders that are really big (as many have said, it is probably because symlinks aren't supported in exFAT. When I transfer these files over to btrfs, will the symlinks come back or are they permanently gone?) but, with the uninstallation of Steam and Kdenlive (each taking a ridiculous amount of storage), removing a couple games I don't really play, and removing old folders that lingered around from already uninstalled programs means I now have enough space to fit my home folder in the SSD (like 23 GiB left, so the lack of symlinks still hurts, but still, it fits!)

When running

rsync -Paz /home/sbird "/run/media/sbird/My Passport/sbird"

As told by someone, I run into a ran out of storage error midway. Why is this? My disk usage is about 385 GiB for my home folder, and there is around 780 GiB of space in the external SSD (which already has stuff like photos and documents). Does rsync make doubly copies of it or something? That would be kind of silly. Or is it some other issue?

Note that the SSD is from a reputable brand (Western Digital) so it is unlikely that it is reporting a fake amount of storage.

EDIT: Wait, is it because my laptop SSD is BTRFS and the external SSD is exFAT? Could that be the issue? That would be kind of weird, why would files become so much more bigger with the external SSD?

Thanks everyone for your help to troubleshoot! It was super helpful! Now I need to go to bed, since I've been up so late it's already tomorrow!

Personally, I have no more tips that those that have already been presented in this comment section. What I would do now to find out what’s going on is the age-old divide-and-conquer debugging technique:

Using rsync or a file manager (yours is Dolphin), only copy a few top-level directories at a time to your external drive. Note the directories you are about to move before each transfer. After each transfer check if the sizes of the directories on your internal drive (roughly) match those on your external drive (They will probably differ a little bit). You can also use your file manager for that.

If all went fine for the first batch, proceed to the next until you find one where the sizes differ significantly. Then delete that offending batch from the external drive. Divide the offending batch into smaller batches (select fewer directories if you tried transferring multiple; or descend into a single directory and copy its subdirectories piecewise like you did before).

In the end you should have a single directory or file which you have identified as problematic. That can then be investigated further.

Oh that's actually a good idea. Thanks person! I will report back soon

[–] sbeak@sopuli.xyz 1 points 3 weeks ago (5 children)

Something interesting that I found: according to dolphin, many folders have many GB extra (e.g. 52GB vs 66GB for documents folder which is kind of crazy) while filelight records 52GB vs 112GB for documents folder, which if true, is kind of insane. Using du -sh records 53G vs 136G (they're the same when using --apparent-size, weird. Specifically for Godot directory, it's 3.8GB vs 41 GB!!!)!!! Files like videos and games seem to be about the same size, while Godot projects with git are much bigger. Weird.

[–] bleistift2@sopuli.xyz 2 points 3 weeks ago (1 children)

These differences really are insane. Maybe someone more knowledgeable can comment on why different tools differ so wildly in the total size they report.

I have never used BTRFS, so I must resort to forwarding googled results like this one.

Could you try compsize ~? If the Perc column is much lower than 100% or the Disk Usage column is much lower than the Uncompressed column, then you have some BTRFS-specific file-size reduction on your hands, which your external exFAT naturally can’t replicate.

[–] sbeak@sopuli.xyz 0 points 3 weeks ago

percentage of total is 83% (292G vs uncompressed 349G apparently)

[–] bleistift2@sopuli.xyz 1 points 3 weeks ago (1 children)

It’s good you found some pathological examples, but I’m at the end of my rope here.

You can use these examples and the other information you gathered so far and ask specifically how these size discrepancies can be explained and maybe mitigated. I suggest more specialized communities for this such as !linux@lemmy.ml, !linux@programming.dev, !linux@lemmy.world, !linux4noobs@programming.dev, !linux4noobs@lemmy.world, !linuxquestions@lemmy.zip.

I have cross posted to a Linux community. Thank you so much for all your help :DDDD

With Dolphin Godot directory is 1GB vs 5GB. Why is there a difference between filelight, dolphin, and du -sh? So weird

[–] sbeak@sopuli.xyz 1 points 3 weeks ago

Something about never knowing the time when one has two clocks

[–] sbeak@sopuli.xyz 1 points 3 weeks ago

it looks like much of the extra Godot bulk is in .git and .Godot directories

[–] sbeak@sopuli.xyz 0 points 3 weeks ago

I'm assuming that Filelight count file size differently, and I will be trusting the result from dolphin more

[–] sbeak@sopuli.xyz 0 points 3 weeks ago

using -H with rsync doesn't seem to do anything unfortunately...

[–] sbeak@sopuli.xyz 1 points 3 weeks ago

YIKES, I found that .local is around 30GB on my system ssd, over 50GB in the external SSD. Much of that is due to Steam and Kdenlive. I can try uninstalling Steam...
