Sv: Bug reporting

[Lars Olsson <larso64@outlook.com>]

I am sorry, but the error described below only occurs on my Acer Aspire X-605. It does not occur on my Compaq Presario CQ58. Both are running Debian 13.2. The latter is a garbage computer, extremely slow but stable. One difference between them I can think of is that the Acer has KDE and the Compaq MATE.

I am going to check my raspberry too, but it's "headless" so...

Best regards/ Lars

Hi,

I have read this pageand followed the advice to send a request for help here, because I don't know what package that is causing the error. I have been using computers since 1982 and Linux since late 90:s, but I am not a programmer. Only a spare time user and I am nota bene not error free myself.

If I have to give the error a name it should perhaps be »Huge files gets corrupted on Linux».

I can't solve the error myself. The error didn't exist a year ago. I need advice on how to bug-report. 

I have two folders with a large amount of files that I want to make a static backup of (I make regular rsync-backups, but I want a static backup every year or so). One folder is about 80 GB in size and the other around 100GB.

I make two big 7z archives of each folder, but when I test the archives with »7z t» 7z reports that the archive is full of errors. It makes no difference if I make one huge archive or split them into 4 gigabyte or 2 gigabyte parts. Same result when I test with zip. (I have not tested tar, gz, xz or any other of the more Linux typical apps mostly because I haven't found a password option in any of them). If I do like this:

7z a -mx0 -p****** -r -sccUTF-8 -scsUTF-8 -t7z -v2g /media/myname/233gb/users/archive-251231.7z Folderwithmanyfiles

The errors on the archive files are printed like this.

1. The errors does luckily not appear in older archives from 2024 and 2023.
   
   
2. The errors only appear when I make new archives, regardless if they are two huge files or split into 4Gb och 2Gb files.
   
   
3. The errors does not occur if I make the archives on my older and much slower Win-laptop.
   
   
4. If I take the time to make the archives on Windows they are error-free (as expected), and when I then move them to my Debian computer with or via an external USB-drive, the errors occur on the files when they are copied to Linux regardless if the external usb-drive is formatted with ext4, ntfs or exfat. (you can imagine the amount of time I've put on testing 🙂).
   
   
5. It also happens if I instead try to copy the files made on Windows to my Debian computer via scp (haven't tested with ftp). 

The error should be easy but rather time-consuming to reproduce. Just do something like below on a huge folder with thousands of files. The archive files I make are put on a usb-drive and I tested with two different usb-drives (actually one SSD in a cheap cabinet and one M.2 NVMe in an ASUS TUF cabinet, highly recommended). 

7z a -mx0 -p****** -r -sccUTF-8 -scsUTF-8 -t7z -v2g /media/myname/233gb/users/archive-251231.7z Folderwithmanyfiles

Best regards
