[Bug 607560] Re: jbd2 writing block every 5 - 10 seconds, preventing disk spin-down and making noise

  Thread Previous • Date Previous • • Thread Next 
This bug also conserns Lenovo B575e models.

Odd kworker and ext4lazyinit activity which results in constant hdd-
activity light blinking. Interesting that this did'n _not_ affect ie.
Ubuntu 14.04. Tested within about two hour timeframe.

Xubuntu 14.04

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.
