Hello After reading some archived list msg [1], and database formats doc (quotas topic)[2], I realized that there is not a "high level" cyrus command to display total disk/partition space actually used at a Cyrus imap backend. In order to get exact (approximated when single instance store is enabled) to be expunged messages space should a du / df be used ? df_used_blocks - used_quota = space_to_be_expunged Is there a better approach (more exact, faster, lower system load)? What is the correct way to account for the single instance store effect? df or du -L ? (du -L)-(du)? At big partitions (with millions of messages) du may cause a high disk load... Suggestions?
