S01031

## Error Message {#error_message .section}

`[TieredStorageMgmt]: To configure coldVolumes with S3 directories, the awss3 plugin must be preloaded by configuring preloadModules. RefId:S01031`

## Probable Causes {#probable_causes .section}

Since tiered storage requires the AWS S3 plugin, after enabling the tiered storage feature, the server will check during initialization if the AWS S3 plugin has been preloaded by configuring *preloadModules*. If the plugin has not been preloaded, this error is thrown.

## Solutions {#solutions .section}

Added configuration parameter `preloadModules=plugins::awss3` in the cluster configuration file.
