I installed the bitcoind and started it as daemon.
After 10hours I’ve tried “du -h”
ubuntu@ip-172-31-37-93:~/.Bitcoin$ du -h
16K ./database
59M ./blocks/index
29G ./blocks
646M ./chainstate
30G .
How to know if it synced or not?
UPD found an interesting script to monitor node sync status How to check Bitcoind block chain download progress level
