Hi @touhidurrr ,
Then it’s possible that you aren’t able to check the disk space, because there isn’t really a disk available to you, just a fixed amount of storage (2 GB for an M2) on a disk that you share with other tenants: you can find all the limitations of shared Clusters here
You may be able to check the space a given database is taking up (DATABASE_STORAGE_SIZE), with the getDatabaseMeasurements instead.
