[Bug 1567567] [NEW] fsck taking way too long 20 hours & still going

[DD Park]

Public bug reported:

Hi, I have a 24T file system ext4, ran fsck. It is running fsck for 20 hours so far and looks like it will keep on going. 
The system is not a slow machine at all, relatively new server.
I checked top and saw that CPU usage was not high. I seen similar problem like this before but CPU usage
was high in the past.

I'm using ubuntu-14.04.4 lts. and running this on the 2nd extra copy of the superblock. I didn't want to
do it with the main copy. I ran e2image -r -s  on the main superblock but it wouldn't create an image file.

I doubt that anything useful is happening and I don't know how to debug this further so please advise
if I should keep it going else I'm likely to shut it down soon
