My hard drive is full when running solana-test-validator

Question

My hard drive is full when running solana-test-validator. I run it on wsl2 on window. Has anyone had this problem and how to fix it? Thanks

Answer 1

You can use the --limit-ledger-size argument to solana-test-validator. Here's the help text:

        --limit-ledger-size <SHRED_COUNT>
            Keep this amount of shreds in root slots. [default: 10000]

Shreds are roughly 1kb, so the default should use up to ~10MB. Otherwise, the account data itself will also take up space, so be sure to avoid using too many large accounts.
