Is there still at 2TB limit?

Is there still at 2TB limit?

[Dale Amon]

I've got to make a very large file system and ran 
across old discussions on a patch for the 2TB file
system size problem.

Is this standard in 2.6.0 kernels? What filesystem size
and file size limits are there currently?

In 2.6.x kernels you are also limited by the 2 TiB limit on block device
sizes, limit which you can extend compiling a 2.6.x kernel with "Large
Block Device" support (menu "Device Drivers" -> "Block devices", at the end).

You will also need filesystems that support that big sizes and can hold
big files on them, have a look at the following URL for more information:

Thanks. I notice the notes there are quite old. Are 
there libraries available now that work with LFS?

Actually I've got the answer. glibc 2.1.3 has full api;
glibc 2.2 has full support; I'm currently using glibc
2.3.2ds1 so if I toggle on that LFS option, it should
all just work merrily with many terries of bytes.

Yes.  Most glibc are distributed compiled with _LARGEFILE64 support.

I haven't got around to updating for 2.6.0, but the 2.5 notes still
apply.
