By default mtd partitions were like

cat /proc/partitions
major minor  #blocks  name

  31     0       8192 mtdblock0
  31     1        256 mtdblock1
  31     2       2048 mtdblock2
  31     3       5824 mtdblock3
  31     4         64 mtdblock4


mtdblock3 was having 5824 blocks and 5824 blocks were able to use,

I think you are missing my point, i have increase size of mtdblock3 but i am unable use whole partion and idk why

kindly also inform me how i can change erasesize of a partition

5884 is the raw size of mtdblock3.

5824 is the usable size of the file system on mtdblock3, i.e. after subtracting
the overhead for file system bookkeeping.
