---------------------------------------
Sprint: Resource Mgmt: RI-17 Sprint 53
Assignee: Benjamin Bannier
> Handle plugin crashes gracefully in SLRP recovery.
> --------------------------------------------------
>
> Key: MESOS-8400
> URL: https://issues.apache.org/jira/browse/MESOS-8400
> Project: Mesos
> Issue Type: Improvement
> Reporter: Chun-Hung Hsiao
> Assignee: Benjamin Bannier
> Priority: Blocker
> Labels: mesosphere, mesosphere-dss-post-ga, storage
>
> When a CSI plugin crashes, the container daemon in SLRP will reset its
> corresponding {{csi::Client}} service future. However, if a CSI call races
> with a plugin crash, the call may be issued before the service future is
> reset, resulting in a failure for that CSI call. MESOS-9517 partly addresses
> this for {{CreateVolume}} and {{DeleteVolume}} calls, but calls in the SLRP
> recovery path, e.g., {{ListVolume}}, {{GetCapacity}}, {{Probe}}, could make
> the SLRP unrecoverable.
> There are two main issues:
> 1. For {{Probe}}, we should investigate if it is needed to make a few retry
> attempts, then after that, we should recover from failed attempts (e.g., kill
> the plugin container), then make the container daemon relaunch the plugin
> instead of failing the daemon.
> 2. For other calls in the recovery path, we should either retry the call, or
> make the local resource provider daemon be able to restart the SLRP after it
> fails.
