Summary

The value of the metadata_max_filesize parameter (or its default value), which is expressed in megabytes, is compared to the file size in bytes for which metadata needs to be generated. However, the conversion from megabytes to bytes is performed by multiplying by 1000000 (1000 * 1000) instead of 1048576 (1024 * 1024).

This means that we believe, by default, the system generates metadata for files smaller than 268435456 bytes (256 MB), when in fact, it's for files up to 256000000 bytes (244 MB).
