Zhitao Li created MESOS-8663: -------------------------------- Summary: Support transfer of persistent volume between roles without losing data Key: MESOS-8663 URL: https://issues.apache.org/jira/browse/MESOS-8663 Project: Mesos Issue Type: Improvement Reporter: Zhitao Li
A persistent volume is scoped to a role right now. On agent, the volume path actually included the role string. A possible workflow from operator side is to transfer the volume onto a new role (i.e, a reorg which transfers the owner of a database to a new team). Today the operator would need to create new volume and delete old volume, during which data could be lost (unless they perform manual data migration out of Mesos control). This would be an operational blocker for us to try out hierarchical roles once they support persistent volume. The goal here is to see whether Mesos can provide an atomic operation which can allow transfer the volume onto a different role without necessity to delete/recreate the volume. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
