Thanks. I'm asking because some days ago I tried to create a 10T ext3 filesytem on a linear software raid over two hardware raids, and it failed horribly. mke2fs from e2fsprogs-1.39 refused to create such a large filesystem but did it with -F, and I could mount it afterwards. But writing data immediately produced zillions of errors and only power-cycling the box helped. We're now using a 7.9T filesystem on the same hardware. That seems to work fine on 2.6.21-rc2, so I think this is an ext3 problem. I cannot completely rule out other reasons though as the underlying qla2xxx driver also had some problems on earlier kernels. We'd much rather have a 10T filesystem if possible. So if you have time to look into the issue I would be willing to recreate the 10T filesystem and send details.
