I don't understand quit well what are the requirements on the disk volume to run a full node of ethereum and what is its expected growth.
e.g. for now I have the following volume distribution across different ethereum folders on an ubuntu machine (listed only the biggest chunks):
16G ./.ethash
12G ./.ethereum
12G ./.ethereum/chaindata
what's exactly there (.ethereum and ./.ethereum/.chaindata seem to have the same size)?
how much disk space does the mining activity require (that's the reason for space in the folder ./.ethash or not?)?
Edit: additional info - content of ./ethash running the ls -l command there
drwxrwxr-x 2 ubuntu ubuntu 4096 Jul 24 07:22 ./
drwxr-xr-x 6 ubuntu ubuntu 4096 Jul 23 18:16 ../
-rw-rw-r-- 1 ubuntu ubuntu 1409284744 Jul 24 07:43 full-R23-03b8bc47a10d1baa
-rw-rw-r-- 1 ubuntu ubuntu 1367339400 Jul 24 00:20 full-R23-1250db2965df18ca
You see big binary files.
