You can verify that on the node be executing the following command : "vdsClient -s 0 getVdsCaps" (-s for secure), There, you should see a supportedENGINEs list. > -¿Its necessary shutdown Nodes to do engine upgrade? no, but take in consideration that after upgrade, those hosts might get into non-operational state, in case VDSM version should be upgraded also. > -¿Are there any problem having the same physical machine for engine and > storage? ¿what are advantages have on diferents machines? There is no limitation of doing that, it's simply a question of the architecture you want to support. Separating the engine from the Storage server, might be useful to make it more high available. > > Thank you > > > _______________________________________________ > Users mailing list > Users(a)ovirt.org > http://lists.ovirt.org/mailman/listinfo/users >
