Could you describe that a little more specifically? In particular, how is
what mounted where? For example, "FOO is running MacOS X 10.1.2, BAR is
running RHL 7.3, and BAZ is running RHL 7.2. BAZ has a large EXT3
filesystem which it is exporting via Samba to BAR, which has it mounted via
smbfs. BAR then re-exports that filesystem via Samba again. FOO has the
filesystem from BAR mounted using the SMB support built-in to MacOS X."
To help narrow down where you are hitting the limit, you might try this:
First, on the RHL 7.2 system (the one with the large disk storage),
attempt to create a large file:
dd if=/dev/zero of=/path/to/testfile bs=1M count=4096
That will take some time, and likely cause the system to slow to a crawl,
so use some care. If it works, remove the test file (that will also take
some time).
Next, on the RHL 7.3 system (the go-between), attempt to create a large
file over the network:
dd if=/dev/zero of=/mnt/firsthost/path/to/testfile bs=1M count=4096
That will take even longer, and likely cause both systems, and every other
computer in the same collision domain, to slow to a crawl. Use more care.
If this isn't your network, you might want to ask you admin first.
You get the idea.
