Study Notes

Zhu Feng and Lin Peng went to UT to update system with modified NFS scripts. The testing result in UT is quite different from those we got in our lab. When mount 15T volume, one node always keeps in 3s, and the other one takes about 10 seconds. If mount 11T,one node 0.04s, the other 2.5s. If mount 7.5T, one node 0.03s, the other 1.5s. For comparing, it takes about 2.5s on each node to mount 15T in our lab. Hence it seems according to UT environment, 7.5T would be the best choice as UT guys need mount operating as short as 1 second and they also want large volume(>10T). Jackie, the testing engineer in UT, did not accept the 2.5s mounting time. He told Zhu and Lin to re-install all the systems and recovery to default statues. Hence, these two guys have to go to UT tomorrow morning. Let’s wait for the result, and I think we also need to let UT know clearly, for their 2.4 kernel, our current version is the best resolution, though we will modify the latest version as 4.0.
