+- Die Option `-f` sorgt dafür, dass ein eventuell schon bestehendes Dateisystem auf den Bricks übeschrieben wird.
+- Zur Option `-i` laut Manual: „The inode size is set to 512 bytes to accommodate for the extended attributes used by GlusterFS.“
+- Zur Option `-n` schweigt sich das Manual aus, lauf Information von [https://rajeshjoseph.gitbooks.io/test-guide/content/cluster/chap-Configuring_Gluster_for_Enhancing_Performance.html hier]: „An XFS file system allows to select a logical block size for the file system directory that is greater than the logical block size of the file system. Increasing the logical block size for the directories from the default 4 K, decreases the directory I/O, which in turn improves the performance of directory operations.“
+- Das Gluster-Manual empfiehlt noch die `-d`-Option, um Striping-Parameter zu setzen. Die sind aber laut [https://rajeshjoseph.gitbooks.io/test-guide/content/cluster/chap-Configuring_Gluster_for_Enhancing_Performance.html der Quelle oben] aber nur nötig, falls unter den Bricks ein RAID liegt.
