Speiel az XFS kakukktojás, mert on-the-fly metaadatlétrehozást használNem, az is statikusan allokált: This space cannot be used for general user data including inodes, data, directories and extended attributes. Ott is simán előfordul, hogy egy AG-ban betelik, ott annyival jobb csak a helyzet, hogy ilyenkor másik, kevésbé telített AG-ba tudja átcsoportosítani a metát. As mentioned earlier, XFS filesystems are divided into a number of equally sized chunks called Allocation Groups. Each AG can almost be thought of as an individual filesystem that maintains its own space usage. The only global information maintained by the first AG (primary) is free space across the filesystem and total inode counts.
