Hi Simon, 1. Most of the chef recipes involve installing the various packages required for the protocols, and some of the new performance monitoring packages required for mmperfquery. There is a series of steps for proper manual install at http://www-01.ibm.com/support/knowledgecenter/STXKQY_4.1.1/com.ibm.spectrum.scale.v4r11.adv.doc/bl1adv_ces_features.htm but this assumes you have all IBM Samba RPMs and prerequisites installed. The recipes *should* be split out so that at the very least, RPM install is done in its own recipe without configuring or enabling anything... 2. I am not 100% sure what deploying IBM Samba on the cluster will do with regards to sernet samba. As far as I am aware there is no code in the installer or chef recipes to check for other samba deployments running but I may be mistaken. Depending on how sernet samba hooks to GPFS I can't think of any reason why it would cause problems aside from the risk of the protocols not communicating and causing issues with file locks/data overwrites, depending on what workload you have running on samba. 3. I haven't personally seen multicluster deployments done or tested before, but no, it is not officially supported. The installer has been written with the assumption that you are installing to one cluster, so I wouldn't recommend trying with multiple clusters - unforseen consequences :)

The docs online seem to list manual installation as running the chef template, which is hardly manual... 1. Id like to know what is being run on my cluster 2. Its an existing install which was using sernet samba, so I don't want to go out and break anything inadvertently 3. My protocol nodes are in a multicluster, and I understand the installer doesn't support multicluster. (the docs state that multicluster isn't supported but something like its expected to work). So... Has anyone had a go at this yet and have a set of steps? I've started unpicking the chef recipe, but just wondering if anyone had already had a go at this? (and lets not start on the mildy bemusing error when you "enable" the service with "mmces service enable" (ces service not enabled) - there's other stuff to enable it)...
