user6744: I have a relay node fully synced with the tip of the mainnet chain and DB-sync filling the Postgres database. DB-sync is currently syncing on epoch 321 and the database takes 103 GB of disk space. I noticed that as epochs move forward more storage space is required (and syncing is much slower).
I currently have only Postgres filling up a disk volume on Linux of total 187 GB.
My question is, what will be the total size of the cexplorer (for mainnet) database? Do I need more than 187 GB? Currently the chain is on epoch 342.

Yes, that is the unfortunate reality.

It will continue growing. There is an SQL query that will tell you the size of the database. Last time I ran that on a fully synced database it was 140G.
