--- Comment #2 from Gregor Mi <codestr...@posteo.org> --- Today, I tried to reproduce the behaviour with some external hard drive on two different USB ports (if this has any influence). But I could not reproduce it. Kernel version: 4.1.36-44-default, openSUSE Leap 42.1, Plasma 5.8.5. I continue to have a watch. @Valerio: Thanks for forum post. A few answers down someone writes that only this one line $ echo madvise > /sys/kernel/mm/transparent_hugepage/defrag should be enough and that "madvise" might have less side effects than "never". One related thing is interesting though: when I used an USB stick instead of the drive and I copied 900 MB to it, I watched in dolphin how the new file size was growing. After it reached to target file size (pretty quickly) the job in the notification area did not stop for another minute or so. Could that be emptying some filesystem cache? -- You are receiving this mail because: You are watching all bug changes.
