Public bug reported:
Large files are reported incorrectly when using the 'ls' command
The expected size should 102G instead, it reports 1402M or 2G
Example of INCORRECT size:
$ ls -1 -s --block-size=M
/mnt/f4/plot-k32-2021-05-08-01-15-1648a669ec6edd5cfb124a1512178c5a2a1a714000f4f52b73efc0c3d91a747c.plot
1402M
/mnt/f4/plot-k32-2021-05-08-01-15-1648a669ec6edd5cfb124a1512178c5a2a1a714000f4f52b73efc0c3d91a747c.plot
Example of CORRECT size (same file):
$ ls -l
/mnt/f4/plot-k32-2021-05-08-01-15-1648a669ec6edd5cfb124a1512178c5a2a1a714000f4f52b73efc0c3d91a747c.plot
