[Lustre-discuss] external journals

[Brock Palen]

Whats a good way to find out if your (our) workload would benefit  
from external journals?  Our OST's are x4500's and I get little if  
any activity on the journals from my regular benchmarks.

What are the benefits?  Does ldiskfs do anything intelligent with  
external journals? What should we see the most help with?  Or should  
be just devote these disks to being another OST?
