No...you can have many, many, many GBs of data in a file system (which
we call a "volume set").  I don't remember the limit, but I suspect
it is somewhere around 255 * 8 GB (I seem to recall that a volume set is
limited to 255 disk drives, and the biggest drive I've seen is about 8 GB).
 
(And, there can be a large number of volume sets, but I don't remember
the limit.)
 
: Does it have LVM to get around this restriction?
 
Well, we don't have the restriction, so we don't need to get around it.
 
The "volume set" definition is similar to Unix' LVM in that a volume
set can span multiple disk drives... but there is one important
major difference: on MPE, a volume set consists of entire disk drives...
you can't have a drive that is part of two different volume sets (unlike,
say, HP-UX where you can have multiple file systems on the same drive).
