And you are totally right, it can be a little fragile at times. So a short explanation: We had this situation on test machines as well. Because of issues with the system not only the mm-commands but also usual Linux commands took more than 10 seconds to return. We have internally a default time out of 10 seconds for cli commands. So if you had a failover situation, in which the cluster manager was changed (we have our cluster state manager (CSM) on the cluster manager) and the mmlsmgr command did not return in 10 seconds the node does not know, that it is the CSM and will not start the corresponding service for that. If you want me to look further into it or if you have feedback regarding mmhealth please feel free to send me an email ([email protected]) Mit freundlichen Grüßen / Kind regards Wagner, Anna Christina Software Engineer, Spectrum Scale Development IBM Systems IBM Deutschland Research & Development GmbH / Vorsitzende des Aufsichtsrats: Martina Koederitz Geschäftsführung: Dirk Wittkopp Sitz der Gesellschaft: Böblingen / Registergericht: Amtsgericht Stuttgart, HRB 243294
