[Bug 1103187] Re: xfs left inconsistent after reboot, causing grub to fail


Phillip Susi, thank you for your comments. Everyone is aware of the
scope of the Bug Description. Despite this, as it would appear you find
not having an updated BIOS a good idea, could you please provide a
technical detail on why having a buggy/more buggy BIOS would be
preferred here?

  xfs left inconsistent after reboot, causing grub to fail

Status in “grub2” package in Ubuntu:
Status in “linux” package in Ubuntu:

Bug description:
  take a 12.10 with XFS root partition containing the /boot/ tree
  dpkg-reconfigure grub-pc ; sync
  reboot (either by command, or by menu)
  diverse error messages + grub rescue + /boot/ is partially accessible

  boot UBUNTU 12.10 pendrive + choose "try Ubuntu" + open a terminal
  sudo -s; mkdir foo; mount [the XFS root partition] foo; umount foo
  reboot into the "original" Ubuntu is NOW successful

  It appears that the kernel xfs filesystem driver leaves the fs in an inconsistent state even after a sync.  That is corrected by a journal playback done either via having the kernel mount or running fsck, but grub does not use the xfs journal.
