Hello,

I am a newbie.  I installed Ubuntu and ran bitcoind from my user account.  After a little while, I got the following message:

2022-04-23T03:48:14Z *** Disk space is too low!
2022-04-23T03:48:14Z Error: Disk space is too low!

I allocated 500GB to / during installation.  When I checked the disk space usage, I got the following:

I am lost as to why so much space is being used by bitcoind.  I would appreciate if someone can shed light on this.
