Rajani Karuturi updated CLOUDSTACK-8629: ---------------------------------------- Security: (was: Public) > Use Ceph RBD storage pool for writing HA heartbeats > --------------------------------------------------- > > Key: CLOUDSTACK-8629 > URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8629 > Project: CloudStack > Issue Type: Improvement > Components: KVM > Reporter: Wido den Hollander > Assignee: Wido den Hollander > Labels: gsoc2017 > Fix For: Future > > > Just like NFS we should write a heartbeat for each Instance to RADOS. > Each hosts could write a simple object like: <pool>/<host ip> > They simply write the timestamp to the object encoded in JSON. > Other hosts can read that object and see if the host wrote the timestamp > lately. If it did it means that it is still up and running and Fencing is not > needed or required. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
