[Ocfs2-users] OCFS2 upgrade question

[Herbert van den Bergh]

The datavolume option didn't really do much.  It just changed the 
filesystem identifier from OCFS2 to OCFS V1, so some programs which 
shall not be named would detect it as OCFS and do something special.  
Those programs have long since been fixed.  And there's absolutely no 
other functional behavior change with or without the parameter.

Thanks,
Herbert.
