How can I get know using geth console was my database synced in fast or full mode ?
UPD
Its not the same as checking a process ps ux | grep geth. I know that i have started geth without sync parameter - i just to get know what a difference from client side on this state.
do a :
eth.getBalance('someaccount',some_block_number_very_back_into_the_past_like_block_1000000_or_so)`
if you get an error about the state entry, then you are in fast sync mode. To have a full node, you will need about 1 TB disk size, and your database will be storing every state change from block 0, so getting a balance of an account back into the past will not produce an error.
--gcmode=archive it will store all states, so it is possible for a node started as full to not return a balance for old blocks.
--syncmodeparameter, then by default you are using--syncmode=fast, so you're doing afastsync, not afullsync.--gcmode=archiveand have 1.5TB+ of storage as of today
