Why does setting some value to vm.dirty_bytes reset vm.dirty_ratio to 0?
Issue
- Why does setting some value to vm.dirty_bytes reset vm.dirty_ratio to 0? (or vice versa)
- Why does setting some value to vm.dirty_background_bytes reset vm.dirty_background_ratio to 0? (or vice versa)
- Why does setting vm.dirty_ratio and vm.dirty_bytes in sysctl.conf set only one of the values? (same for respective background parameters)
- Why does setting vm.dirty_background_ratio to 0 after vm.dirty_background_bytes in sysctl.conf reset the value of vm.dirty_background_bytes to 0?
Environment
- Red Hat Enterprise Linux 7 (and older)
- sysctl setting for vm.dirty_bytes/ratio
- sysctl setting for vm.dirty_background_bytes/ratio
