Hi there Ted!

Thanks for the answer! Of course I understand that when you want to
debug something you really gotta run it from the console, It's just
when I started to run this, I did not think anything would go wrong,
you never think it hits you ;)

After e2fsck failed for the first time (where I don't know why, since
gparted crashed after I tried to save the details), I started to run
e2fsck manually, and since the -p option made him cancel the run I
started a third run in interactive mode. I've posted the console
output of this second and third run as an update to my question at
serverfault.com (see
http://serverfault.com/questions/446074/e2fsck-extremely-slow-although-enough-memory-exists
- start reading at "UPDATE4")

The 3rd run is still running (since about 20 hours now) and showing
the same pattern as the first run that failed after 78 hours.


Thanks for looking at this,

Thomas K.
