Running the unstable branch, mkcephfs fails when trying to create
a 3GB journal file on the OSDs.
Relevant messages from the osd logfile:
2010-12-09 19:03:54.419737 7fdde4d51720 journal _open_file: unable to extend journal to 18446744072560312320 bytes
2010-12-09 19:03:54.419789 7fdde4d51720 filestore(/osd) mkjournal error creating journal on /osd/journal
The problem is that the calculation of the journal size in bytes
overflows, in FileJournal::_open_file().
