Re: [Bug 1073433] Re: Ext4 corruption associated with shutdown of Ubuntu 12.10

 

This does seem to be getting kind of embarassing. With modern journalled
filesystems on relatively straightforward hardware configs an unclean
shutdown shouldn't be the end of the world (after all, power failures
can happen), but it's not "nice" either. 

Unfortunately we also seem to have a hell of a lot of noise on Launchpad
about this, people conflating different issues and causes, not reading
previous posts properly, etc., etc.

I'll be upgrading to 14.04 from 12.04 for main machines when it comes
out, if the problem's still present then I will have another look. Last
time I did, my own problems were caused by dhclient and ureadahead.. I
can't remember which if any of those have now been fixed. If nothing
else, pushing those fixes out will show if there are other outstanding
shutdown problems affecting a lot of users.

Title:
  Ext4 corruption associated with shutdown of Ubuntu 12.10

Status in Upstart:
  Confirmed
Status in “linux” package in Ubuntu:
  Incomplete
Status in “network-manager” package in Ubuntu:
  Triaged
Status in “upstart” package in Ubuntu:
  Confirmed

Bug description:
  1. Format and label a target Ext4 partion using Ubuntu 12.04
  2. Install 64bit 12.10 OS using that target without reformatting it
  3. Shut down 
  4. Boot an alternate copy of Ubuntu
  5. Restart selecting the newly installed OS
  6. Login then shutdown
  6. Boot an alternate copy of Ubuntu
  7.Fsck the newly installed OS allowing corrections to be made

  Each time the the newly installed OS is executed and then shutdown,
  even if execution only consists of logging on, a subsequent fsck will
  FAIL.

  I used Acronis True Image Home 2013 to create an image of the newly
  installed 64-bit Ubuntu 12.10, so I can recreate the symptoms of Ext4
  filesystem corruption 100% of the time by restoring from the image,
  booting, logging on and shutting down.
