Document using multiple block devices with S3 storage volumes.

[rfraposa]

(1) Can S3 storage volumes also use "multiple block devices" same as other storage types? (2) If using S3 backed MergeTree, can the configuration use_environment_credentials be used with multiple S3 volumes? (if so, must these environment credentials be the same for both volumes or can they differ somehow?)

Alexey Milovidov Yes, they can use multiple volumes. For example, you can spread the data across multiple s3 buckets. No, environment credentials are common for all disks.

thanks for filing this - I was going to try to edit/PR the page although I think we should include a configuration example on this also, so may require some additional testing and verification first
