--------------------------------------
Summary: SLRP does not clean up destroyed persistent volumes.
Key: MESOS-9544
URL: https://issues.apache.org/jira/browse/MESOS-9544
Project: Mesos
Issue Type: Bug
Components: storage
Affects Versions: 1.7.1, 1.7.0, 1.6.1, 1.6.0, 1.5.2, 1.5.1, 1.5.0
Reporter: Chun-Hung Hsiao
Assignee: Chun-Hung Hsiao
When a persistent volume created on a {{ROOT}} disk is destroyed, the agent
will clean up its data:
https://github.com/apache/mesos/blob/f44535bca811720fc272c9abad2bc78652d61fe3/src/slave/slave.cpp#L4397
However, this is not the case for PVs on SLRP disks. The agent relies on the
SLRP to do the cleanup:
https://github.com/apache/mesos/blob/f44535bca811720fc272c9abad2bc78652d61fe3/src/slave/slave.cpp#L4472
But SLRP simply updates its metadata and do nothing:
https://github.com/apache/mesos/blob/f44535bca811720fc272c9abad2bc78652d61fe3/src/resource_provider/storage/provider.cpp#L2805
This would lead to data leakage if the framework does not call `CREATE_DISK`
but just unreserve it.
