Damodar Reddy T resolved CLOUDSTACK-5679. ----------------------------------------- Resolution: Cannot Reproduce When we are adding a rule to the iptables to block the connection it is not dropping connections which are already established and new connections are rejected to that DB node.. Kiran: I am not sure how to add a rule to drop even established connections as well, so I tested by stopping the db node and able to see exceptions in logs of 2nd MS node.. > No Error message is shown when the Connection from the MS is lost Db server > in case of multiple MS and DB HA enabled. > --------------------------------------------------------------------------------------------------------------------- > > Key: CLOUDSTACK-5679 > URL: https://issues.apache.org/jira/browse/CLOUDSTACK-5679 > Project: CloudStack > Issue Type: Bug > Security Level: Public(Anyone can view this level - this is the > default.) > Components: Management Server > Affects Versions: 4.3.0 > Reporter: Kiran Koneti > Assignee: Damodar Reddy T > Priority: Critical > Fix For: 4.3.0 > > > Setup and issue details: > 1)Created a CS setup with multiple MS say MS1 and MS2 with DBHA enabled. > 2)Created a DB replication has 2 db servers say DB1 and DB2. > 3)Initially the setup was in such a way that both MS1 and MS2 are talking to > the DB1 and DB2 was acting as a slave. > 4)Then Blocked the communication from the MS2 to DB1 using the IPtables. > 5)When the connection is blocked from the MS2 to DB1 there is no error > message shown in the logs and it simply switches to the DB2 . -- This message was sent by Atlassian JIRA (v6.1.5#6160)
