Same here (however, I was putting XFS into game first); JFS on AIX is
very stable.
However, one has to clearly distinct JFS from JFS2... (at least in the
AIX world, see wikipedia which states 'In the other operating systems,
such as OS/2 and Linux, only the second generation exists and is called
simply JFS.[3] This should not be confused with JFS in AIX that actually
refers to JFS1.' [0])
