We have on-prem Splunk Ent, and considering using AWS S3 Glacier to move frozen data. I know it is possible, but question I have is,
can I configure S3 Glacier, so it will appear as local disk or mount in our indexers?
While you can mount an S3 bucket as a local disk, you'll probably want to age the data from your indexers using the Hunk Data roll feature as documented here: How Hunk Data Roll Works Setting up Data Roll
