Hi Casey,
thank you so much for analysis! We tested the upgraded intensively, but the buckets in our test environment were probably too small to get dynamically resharded.
after upgrading to the Quincy release, rgw would look at the wrong object names when trying to list those buckets. As we're currently running Quincy, do you think objects/bucket indexes might already be altered in a way which makes them also unusable for Reef?
for multisite resharding support, the bucket instance metadata now stores an additional 'layout' structure which contains all of the information necessary to locate its bucket index objects. on reshard, the Red Hat pacific release would have stored that information with the bucket. the upstream Reef release should be able to interpret that layout data correctly however, if the Quincy release overwrites that bucket instance metadata (via an operation like PutBucketAcl, PutBucketPolicy, etc), the corresponding layout information would be erased such that an upgrade to Reef would not be able to find the real bucket index shard objects
