sorry. No-Can-Do. Not in 2.4 anyway. Maybe in 2.6...

2 time 1.1TB > 2TB.

2TB is the most you can access with 32bits addressing for 512byte
sectors.

You are hitting an error at (1K) block 134217729 which is 1 block past
2TB.

If you make the sdb1 and sdc1 partitions less than 1TB you have a
better change of it working.
