And, FWIW, making the warning go away if probably a bad idea, because XFS only supports devices with sector sizes up to 32k: #define XFS_MIN_SECTORSIZE_LOG 9 /* i.e. 512 bytes */ #define XFS_MAX_SECTORSIZE_LOG 15 /* i.e. 32768 bytes */ And so it should be warning about devices trying to tell it to use something larger....
