Hello @bhj35,  
Welcome to the forum!

Your database is failed to pass preflight checks.

1. Stop the storagenode
2. Execute either with a local installed sqlite3 or with a docker container (for ref: [https://support.storj.io/hc/en-us/articles/360029309111-How-to-fix-a-database-disk-image-is-malformed-](https://support.storj.io/hc/en-us/articles/360029309111-How-to-fix-a-database-disk-image-is-malformed-)):

```auto
sqlite3 storage_usage.db
drop table test_table;
.exit

```

1. Start the storagenode and check 20 lines of your logs again.
