Public bug reported:
'man resize2fs' claims "If no units are specified, the units of the size
parameter shall be the filesystem blocksize of the filesystem" but
makes no mention of the units used in the minimum size report. The tool
itself makes no mention of units.
Many users would assume the value was in bytes, or possibly KB.
Despite the fact that the operating deals in file-system block-size
units the output appears to be in units of 512-byte sectors.
$ sudo dumpe2fs /dev/fujiVG/home | grep 'Block size'

$ sudo resize2fs -P /dev/fujiVG/home
resize2fs 1.42 (29-Nov-2011)
Estimated minimum size of the filesystem: 5124061
