-----------------------------
Summary: Allow optional `profile` to be specified in `CREATE_DISK`
offer operation.
Key: MESOS-9275
URL: https://issues.apache.org/jira/browse/MESOS-9275
Project: Mesos
Issue Type: Task
Components: resource provider
Reporter: Jie Yu
This will allows the framework to "import" pre-existing volumes reported by the
corresponding CSI plugin.
For instance, the LVM CSI plugin might detect some pre-existing volumes that
Dan has created out of band. Currently, those volumes will be represented as
RAW "disk" resource with a volume ID, but no volume profile by the SLRP. When a
framework tries to use the RAW volume as either MOUNT or BLOCK volume, it'll
issue a CREATE_DISK operation. The corresponding SLRP will handles the
operation, and validate against a default profile for MOUNT volumes. However,
this prevents the volume to have a different profile that the framework might
want.
Ideally, we should allow the framework to optionally specify a profile that it
wants the volume to have during CREATE_DISK because it might have some
expectations on the volume. The SLRP will validate with the corresponding CSI
plugin using the ValidateVolumeCapabilities RPC call to see if the profile is
applicable to the volume.
