[Lustre-discuss] 8T Limit

[Peter Jones]

Yes, that is correct. So far we have only tested on RHEL5, but I believe 
that this should also work in theory on SLES11. However, we have so far 
been unable to find a volunteer able to help with SLES11 testing to 
confirm that the practice matches up with the theory. I have been 
talking with a couple of our OEM partners about this possibility so 
hopefully we can get this done in the near future. A couple of sites 
have been testing 16TB LUNs on RHEL with a pre-release version of 1.8.2 
and the feedback so far has been positive.
