<DIV>Hello Everyone,</DIV>
<DIV> </DIV>
<DIV>being the local crafty busy admin for a neuroscience research branch, Lustre seems the only way to go however I'm a bit stuck and need some thoughtful guidance.</DIV>
<DIV> </DIV>
<DIV>My goal is to setup a virtual OS environment which is a replica of our </DIV>
<DIV>Direct attached storage head node running SLES 11.0 x86 64 Kernel: 2.6.27.19-5 default #1 SMP</DIV>
<DIV>and our (2) Dell blade clusters running CentOS 5.3 x86 64 Kernel: 2.6.18-128.el5 #1 SMP</DIV>
<DIV>which I now have running as a) SLES 11 same kernel MDS b) SLES 11 same kernel OSS and c) CentOS 5.3 x86 65 same kernel</DIV>
<DIV>and then get Lustre running across it.</DIV>
<DIV> </DIV>
<DIV>The trouble began when i was informed that the Lustre rpm kernel numbers MUST match the OS kernel number EXACTLY due to modprobe errors and mount errors on the client,</DIV>
<DIV>and some known messages on the servers after the rpm installs.</DIV>
<DIV> </DIV>
<DIV>My only direct access to Oracle Lustre downloads is through another person with an Oracle ID who's not very willing to help - i.e. this route is painful</DIV>
<DIV> </DIV>
<DIV>So to explain why I'm stuck:</DIV>
<DIV> </DIV>
<DIV>a) access to oracle downloads is not easy</DIV>
<DIV>b) there is so much risk with altering kernels, given all the applications and stability of the environment you could literally trash the server and spend days recovering - in addition to it being the main storage / resource for research </DIV>
<DIV>c) I can't seem to find after looking Lustre RPMs that match my kernel environment specifically, i.e. the SLES 11 AND CENTOS 5.3</DIV>
<DIV>d) I've never created rpms to a specific kernel version and that would be a deep dive into new territory and frankly another gamble</DIV>
<DIV> </DIV>
<DIV>What's the least painful and least risky to get Lustre working in this prototype which will then lend to production (equally least painful) given these statements - Help !</DIV>
<DIV>Cliff, I could use some details on how specifically wamcloud can fit this scenero - and thanks for all the enlightenment.</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>thanks for your help</DIV>
