Let's go with Nathan's hunch - what version of the kernel are you using?
the BLKGETSIZE64 iocttl was broken for a while, and returned bad values.
That could be causing your problem...
THe default internal log grows with the size of the fs, to a point. But
aside from some overall min/max log sizes (probably documented in the
mkfs.xfs man page) you can have a wide range of log sizes for a given fs.
Log v1 is still default, logv2 could probably use more testing before
it becomes the default.
