Do a chdir to /mammoth, go to a directory your current user (which isn't
root) can write to, and do

Probably bonnie++ -s 2*your_memory -d. -n64

the 2*your_memory is in megabytes so if you have 4 GB memory do:

bonnie++ -s8192 -d. -n64

If you notice that file operations field in the results gets printed as
stars (***), double the "64" argument (measured in thousands of files)
and try again.

So you're doing software RAID5 over three hardware RAID6 arrays? Nice :)
I hope your physical setup can make use of such redundancy.

It will be interesting to see this results!
