+Subject: [PATCH 539/539] extras: disable lookup-optimize in virt and block
+ groups
+
+lookup-optimize doesn't provide any benefit for virtualized
+environments and gluster-block workloads, but it's known to cause
+corruption in some cases when sharding is also enabled and the volume
+is expanded or shrunk.
+
+For this reason, we disable lookup-optimize by default on those
+environments.
