[Lustre-discuss] 1.6.3 -> 1.6.4.2 upgrade

[Charles Taylor]

Turns out that the client upgrade worked just fine.   I had not  
noticed that the ko2iblnd module was not in place.

I'm still wondering if I need to do anything special with regard to  
upgrading the MGS/MDS and OSSs.   I'm hoping to just dump the  
software in place and reboot with live clients.   Seems kind of  
risky, but hey, the docs say you can do it for 1.4 -> 1.6.3 so going  
from 1.6.3 -> 1.6.4.2 ought to be a no-brainer, right?   :)
