[Bug 1187214] Re: "ext4-fs error" -- Ubuntu upgrade from 12.10 to 13.04 corrupted filesystems (ext4 corruption bug)


Kristian Erik Hermansen, this bug was reported a while ago and there
hasn't been any activity in it recently. We were wondering if this is
still an issue? If so, could you please test for this with the latest
development release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release (installed or live) from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:

Bug description:
  I thought it would be a good idea to upgrade from 12.10 to 13.04.
  Apparently, Ubuntu likes to corrupt my data. My configuration has
  4xHDD in RAID0 using ecryptfs of user data only. 70% into the upgrade
  process using the recommended GUI upgrade option, the process failed,
  the ext4 file-system became corrupted and all data was lost.
  Eventually, my kernel crashed shortly afterwards and rebooted. I was
  able to snap a quick photo, but it is only the last page of the
