I'm testing out the ability to restore from an S3-backed datastore and set up a new VM w/ PBS installed along w/ an S3 endpoint and datastore that point to an existing bucket that my main PBS instance is syncing to.

On this new VM, when syncing the S3 datastore to a local datastore, there are hundreds of these warnings (found empty chunk '<hash>' in store s3-store, overwriting) that show up in the task log viewer.

I've run a GC/Prune/Verify on the main PBS instance against the S3 store and everything comes back clean.

Is this expected/harmful? It's not clear what, if any, issues are present with these warnings.
 
Hi,
yes this is expected if the chunk has been evicted from the local datastore cache since the last time it has been seen. This indicates that the chunk is being re-inserted into the local store cache.
