From b766bf7fc9787b2516eee2eac6f00dd03a327b8b Mon Sep 17 00:00:00 2001 From: Anshul Gangwar Date: Tue, 10 Jan 2017 17:10:28 +0530 Subject: [PATCH] CLOUDSTACK-8862: Introduced new state attaching for volume. This will make sure that other attach operation on same volume will fail gracefully without calling access calls for managed storage like SolidFire Also, skipping test_upload_attach_volume as there is no implementation which supports this. --- api/src/com/cloud/storage/Volume.java | 7 +- .../orchestration/VolumeOrchestrator.java | 11 +- .../cloud/storage/VolumeApiServiceImpl.java | 216 ++++++++++-------- test/integration/component/test_stopped_vm.py | 11 +- 4 files changed, 150 insertions(+), 95 deletions(-) diff --git a/api/src/com/cloud/storage/Volume.java b/api/src/com/cloud/storage/Volume.java index f70ead93718..133a59df8a6 100644 --- a/api/src/com/cloud/storage/Volume.java +++ b/api/src/com/cloud/storage/Volume.java @@ -51,7 +51,8 @@ public interface Volume extends ControlledEntity, Identity, InternalIdentity, Ba NotUploaded("The volume entry is just created in DB, not yet uploaded"), UploadInProgress("Volume upload is in progress"), UploadError("Volume upload encountered some error"), - UploadAbandoned("Volume upload is abandoned since the upload was never initiated within a specificed time");
