Re: inquiry concerning tar maximum archive size

[grenoml]

Paul,
  Thanks for the reply.

  I'm using the ext3 journaled file system under RedHat and I'm not
aware of any low file size limitations with ext3.

 The target filesystem has plenty of space for storage.

 The filesystem in question (/usr) now has about 11.4G used that is
being archived.  It is the largest of all the filesystems.  There is no
single file within the filesystem that is larger than 8GB.

  Most of the resulting compressed filesystem archives come in at under
2GB for filesystems that are all under 8GB of used capacity except for
the filesystem which is having the problem.

 RedHat provides tar via rpm but I have no idea how it was compiled.

 I'm also going to post an inquiry to the redhat list regarding the
issue.
 
thx,
Gerry Reno
