[jira] [Created] (MESOS-9049) Agent GC could unmount a dangling
persistent volume multiple times.
Chun-Hung Hsiao created MESOS-9049:
--------------------------------------
Summary: Agent GC could unmount a dangling persistent volume multiple times.
Key: MESOS-9049
URL: https://issues.apache.org/jira/browse/MESOS-9049
Project: Mesos
Issue Type: Bug
Components: agent
Affects Versions: 1.4.2, 1.5.2, 1.7.0, 1.6.1
Reporter: Chun-Hung Hsiao
Assignee: Chun-Hung Hsiao
When the agent GC an executor dir and the sandbox of one of its run that contains a dangling persistent volume, the agent might try to unmount the persistent volume twice, which leads to an {{EINVAL}} when trying to unmount the target for the second time.
Here is the log from a failure run of {{GarbageCollectorIntegrationTest.ROOT_DanglingMount}}:
