Isn't that the other way around? The file system has allocated a total of 299 GB across devid 1 (to system, metadata and data), and of those, 254 GB are in actual use currently. Remember btrfs "overallocates" so it doesn't have to constantly allocate more space for each separate kind of usage as data is added to the file system. That does not radically alter your conclusion, though. 36 GB is still only a small fraction of the total amount of data stored, assuming that the btrfs tool output you showed can be trusted. -- Michael Kjörling • http://michael.kjorling.se • [email protected] “People who think they know everything really annoy those of us who know we don’t.” (Bjarne Stroustrup) -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
