Source: debian-reference Version: 2.68 Severity: minor Dear Maintainer,
tarting with "Even simply reading a file on the Debian system..." does not correctly reflect the behaviour of "relatime". In the reference it is written, that also "relatime" skips the operation (of renewing the atime-stamp of a file). So this not true for Debian 9.x. Please try this: echo "some text" > file_test stat file_test ==> All three timestamps are more or less the same Now go on: echo "Additional text" >> file_test stat file_test ==> Timestamps mtime,ctime changed, atime did not change Now go on: cat file_test stat file_test ==> timestamp atime has no changed Again: cat file_test stat file_test ==> timestamp atime remains the same Now go on: Wait one or two days: stat file_test ==> note the timestamps cat file_test stat file_test ==> timestamp atime has chenged OR alternatively: echo "Some more text" >> file_test stat file_test ==> timestamps mtime, ctime have changed,timestamp atime is older Go on: cat file_test stat file_test ==> timestamp atime has changed === End of procedure == I have no idea how to explain this shortly, but i was struggling many hours to find out, how "relatime" works, because i thought that the updating of timestamps will be really skipped. Skipping seems to be true only for "noatime" BR Christian -- System Information: Debian Release: 9.3 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-4-amd64 (SMP w/1 CPU core) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system)
