From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Unreliable samba transfers - common issue? (lemmy.ml)

I'm running Jellyfin on a Debian-server in my home, and I have the associated media folders set up as samba shares so that I can transfer any new media from my laptop to the server through Dolphin (KDE file manager).

This has for the most part worked very well (except slow speeds), but I've had an issue recently where the files are not copied over properly. This resulted in glitches in for example music files that would stop playback. I checked the checksums of some of these files, and they were different from source. Seems like the glitchy files are missing some data, but at no point were I notified about this. It works fine after I removed the files and transferred again, and now the checksums match.

Is this a common issue with samba, or could it be a sign that my HDD is acting up?

I don't know if samba has any error checking built in, so it may be even down to wonky network.

I would try doing a copy using rsync or ssh (sftp - you can use dolphin for that too), and see if that helps.

rsync was written by one of the original Samba developers. I wonder if Tridge and co have any idea about how to shuffle data from A to B safely?

CIFS/SMB will only indicate received and not received and written. This is unlikely to be an issue.

I would start by proving that my network works properly, especially that dodgy cable with only wires 1,2,3,7 connected - because that's all 100Mb/s needs, or the solid core cable that runs for 150m with plugs at each end instead of sockets and drop leads.
