--------------------------------------
Summary: Redundant router: Router switch to MASTER then
immediately switch back to BACKUP would failed to work
Key: CLOUDSTACK-2682
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-2682
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Affects Versions: 4.2.0
Reporter: Sheng Yang
Assignee: Sheng Yang
Fix For: 4.2.0
The scripts master.sh and backup.sh are called at the same time when the
"backup" RvR switch to MASTER then immediately back to BACKUP, because of the
file lock mechanism we're using, there is a chance that backup.sh may be called
before master.sh, then result in router seems in MASTER state(though keepalived
still reports BACKUP state).
