https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=195972 Bug ID: 195972 Summary: mmap write (to a zfs filesystem) does not update file modification time Product: Base System Version: 10.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: la5lbtyi@aon.at Scenario: - amd64 machine - a program mmaps a file of approximately 250G size and writes to various locations Result: - The program exits cleanly - The data has been written (this has been verified) - The file's modification time has *not* changed Expected result: - The file's modification time reflects the time of the last write to the file. Notes: - This worked correctly on FreeBSD 9.2, with the exact same program binary (no recompile since). - The binary only links against /lib/libc.so.7. - There has even been a reboot of the machine, and the file's modification time still has not changed although the data has been written. -- You are receiving this mail because: You are the assignee for the bug.
