From the xfsprogs source code: * We don't support filesystems smaller than 300MB anymore. Tiny * filesystems have never been XFS' design target. This limit has been * carefully calculated to prevent formatting with a log smaller than * the "realistic" size. * * If the realistic log size is 64MB, there are four AGs, and the log * AG should be at least 1/8 free after formatting, this gives us: * * 64MB * (8 / 7) * 4 = 293MB So let's accommodate and bump the minimal XFS filesystem size to 300M.
