Hi,
I am currently running a full node, and running out of space. For technical reasons I many not be able to upgrade to storage for a while.
1) If I have some more space on another partition, is there a way to tell Core to concatenate another chainstate folder(s) to the current one?
(So it will use the space I have on another partition).
No it is not possible. However, you can copy the entire data directory to another place and then start Bitcoin core with the command line option
where <path> is the path to the moved data directory.
2) What are the consequences of using pruning? Will that impact my ability to send/receive txs, or it just means I can't fully verify everey tx?
No, pruning just means that old blocks are deleted. This only happens once they have been verified and validated. You will still be able to verify every block and transaction and you will still need to download every single block in the blockchain. Pruning also makes it so that you cannot bootstrap a new node, rescan your wallet, or keep the transaction index.
It does not impact your ability to send and receive transactions.
3) What does the 'n' in "prune=<n>" stand for, and what is a good configuration to use?
Many thanks!
n is the amount of space in MB that you want to reserve for the block and undo files. The minimum is 550. This is to store at least two days of blocks and their corresponding undo files.
