Metadata and caches are exclusively on the SSDs. Hello Rob, would you be so kind and point to some info (docs, howtos) about cyrus tiered storage? All I found is http://www.cyrusimap.org/~vanmeeuwen/imap/features/mail-spool-partitions.html but that seem to be quite tedious to set up. Is your solution similar to that?
