1. On initial start of ColumnStore with SKIP-OAM, if S3 is unavailable, StorageManager will simply come down. MONIT will not notice it for 180 seconds, and mcssystemready() will be returning 1 for all this time. 2. Status of PrimProc is not reflected in mcssystemready. Maybe we should do something here as well. |

This is not a big priority, and whether or when we do it would depend on the tradeoff with the "real" project of doing a real cluster supervision (aka "replace OAM"). But it may well be that these minor improvements would stay, and not be a waste of time, in which case we should do them when convenient. |
