[kernel-bugs] [Bug 1159882] Excessive swapping when buffers / cache expand beyond free physical RAM

http://bugzilla.opensuse.org/show_bug.cgi?id=1159882 http://bugzilla.opensuse.org/show_bug.cgi?id=1159882#c57 --- Comment #57 from Robert Delahunt <radelahunt(a)gmail.com> --- Nevermind, I re-checked and saw the date stamp was 25 September, so I reinstalled (what should be) the new kernel. Here are your new vmstats: http://www.puresimplicity.net/~delahunt/vmstat/mhocko2/ I have 32GB of RAM now but still it dug into about 20 MB of swap, even with swappiness=1. Changing swappiness to 60 during this operation didn't seem to influence how much swap it was using, as it still hovered around 20MB or so. It does this both with a file operation (copying large files to an external 512GB SSD in an enclosure) or zeroizing this drive when finished (dd if=/dev/zero of=/dev/sdc1 bs=4K count=1024 etc) I noticed that running sync after the file copy operation dug into swap, i.e. after terminating the copy command, took a long while. Please advise. -- You are receiving this mail because: You are the assignee for the bug.
