To jump in for Ted here; I'm pretty sure that "very large" is in the
millions range.  Whatever the cause though, the best way for us to be
able to reproduce, diagnose, and fix it is with an image of the
filesystem, even if it is with the file names scrambled ( the names
don't really matter anyhow, just the number and possibly placement of
them ).

Title:
  fsck on 24TB ext4 keeps crashing

Status in e2fsprogs package in Ubuntu:
  Incomplete

  fsck from util-linux 2.20.1
  I can't get my ext4 24TB to fsck clean. there came a whole bunch of file stat problems after a clean reboot.
  I tried 3 times so far, and each does something like segfault. I looked twice, and the errors were different,
  but was able to capture one output. The system has 6GB ram, and it used up all the memory. ended up adding 25GB
  of swap as fsck seems to use up a huge amount of memory. After a long while, usually after mem use is >90%,
  I come back to see the fsck has crashed and file system is still not clean.

  The reboot was clean and should not  have caused any corruption. the
  system is using ubuntu-14.04

  # uname -a
  Linux gigabyte133 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

  I had to use the 64 bit version since the 32 bit version I couldn't get more than 15TB file system built and read 
  that there were compatibility problems between 32bit version with the -O 64bit and the 64 bit version so just
  built the whole thing in 64 bit ubuntu..

  /dev/mapper/raid61p1 contains a file system with errors, check forced.

  Inode 203167820 has compression flag set on filesystem without compression support.  Clear? yes
