I can confirm that at least a 7 TB ext3 filesystem is possible. I have
one 8x1TB RAID5 array running ext3 built with stock SL ext3 tools.

I cannot confirm the 16 TB limit. Can you point us to a reference somewhere?

Here is my information:

I looked into this several years ago when building an 11 TB filesystem. The SL mke2fs
refused to make an ext3 filesystem that big and it turned out that mke2fs sources
had a hardwired limit of 8 TB maximum filesystem size. Instead, I made an 11 TB XFS
filesystem and it is still running just fine thank you very much.
