I'm here again. I did some tests with xfs and jfs umounted here (only reiserfs up) and things didn't change too much. For now, I just made a new setup here in sysctl. Anyone here with rock-solid machines and ups can do the same.
Create a file under this path: $ editor /etc/sysctl.d/60-vm.dirty_writeback_centisecs.conf Inside, you can set another time (default is 500 centiseconds, which is 5 seconds between each wake up). In my case, I'm doing now with 1500 centiseconds. vm.dirty_writeback_centisecs=1500 Put a blank line after the line above, save and exit. Then you can make thing working ASAP without rebooting: $ sudo sysctl -w vm.dirty_writeback_centisecs=1500 The file above is just to preserve your settings between reboots. SIDENOTE: notebook users, this is just a workaround. It won't prevent your hard disks from waking up. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/607560 Title: jbd2 writing block every 5 - 10 seconds, preventing disk spin-down and making noise -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
