Using nodiratime without noatime will turn on touching atime on files everytime the file is read making reading operations more IO heavy.
I've even checked and remounted /data with the instruction above and nodiratime replaced default noatime flag.
So my question still stands:
Wouldn't it be better to use noatime?
BTW, no offense
. I really appreciate all the work you've done. I'm just curious why you made such choice of options. Maybe I'll learn something I didn't know about fs.
