spotted a couple of things 1. "The object's manifest has a tail": could you explain this? 2. >We should probably make it so that when head and tail are being placed > on different placement targets, the head will not contain any data, > other than the object’s metadata. I'd prefer to have the option to retain the small-object optimization, Casey noted this too (conversation); why is this ruled out? regards, Matt -- Matt Benjamin Red Hat, Inc. 315 West Huron Street, Suite 140A Ann Arbor, Michigan 48103 http://www.redhat.com/en/technologies/storage tel. 734-821-5101 fax. 734-769-8938 cel. 734-216-5309
