    Description

      If the client encounters unknown components in a FLR file, it should skip the mirror to choose another known mirror for read/write.

      This provides some forward compatibility for clients accessing mirrored files - they can always read files that have at least one "known" mirror, even if there are other "unknown" mirrors (e.g. compressed, EC, PCC/HSM with some unknown type, etc.).
