Wrong again, got exactly the bad behaviour on Ubuntu 13.10. It's perhaps not related to the issue that started this thread, but since I posted here I thought I might as well inform anyone visiting this that my solution didn't work.
My current thinking is that if you have an NFS4 server with clients attached, and you reboot the server without detaching the clients, you get the bad behaviour. If you umount the clients first, then reboot the server, then mount the clients, the problem doesn't occur. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/607560 Title: jbd2 writing block every 5 - 10 seconds, preventing disk spin-down and making noise Status in “linux” package in Ubuntu: Incomplete Bug description: jbd2 writes blocks to the hard disk every 5 seconds. This makes an annoying click/tick noise and prevents the disk from spinning down to conserve power. jbd2 appears in logs as several entries like... Jul 19 21:35:45 edge kernel: [ 3312.913759] jbd2/sda5-8(350): WRITE block 42280704 on sda5 ... and can be observed using iotop. Since the noise only occurs in Ubuntu and not in Windows 7 it is probably a software problem. The excessive writes may reduce the disk's lifespan. WORKAROUND: Adding commit=60 to the partition's entry in fstab increases the interval to 30-45 seconds.
