Rajesh Battala commented on CLOUDSTACK-3946:
--------------------------------------------
volume copy got fixed with this commit 4cd76b5a9937164283349bb628f2f606aeab28e5
posted the patch not to allow migration if the src and destination pool are
same https://reviews.apache.org/r/13469/
> [KVM] [Zone Wide Primary Storages] migrateVolume is deleting the volume if
> the source and destination pool are same.

> Key: CLOUDSTACK-3946
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-3946
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Storage Controller
> Affects Versions: 4.2.0
> Environment: commit # 6275d697e340be5b520f37b15d72343fa47c00a9
> Reporter: venkata swamybabu budumuru
> Assignee: Rajesh Battala
> Priority: Critical
> Fix For: 4.2.0
>
> Attachments: logs.tgz
>
>
> Steps to reproduce :
> 1. Have at least one advanced zone with KVM cluster (2 kvm hosts)
> 2. Make sure that the setup has at least 2 zone wide primary storages. (from
> ex: zwps1, zwps2)
> 3. Deploy a VM as admin
> 4. Create a datadisk of size 5 GB as admin on zwps1
> 5. attach the above datadisk to the VM in step 3
> 6. detach the data disk
> 7. initiate migrateVolume command for the above datadisk to again zwps1
> Observations:
> (i) volume migrate command involved 2 things
> - copyCommand
> - delete the original
> (ii) In my case, I tried to migrate the volume which is on zwps1 to again
> zwps1. This initiated copyCommand followed by storage.command.DeleteCommand.
> (iii) Due to the issue mentioned in CLOUDSTACK-3943, copy command failed.
> The subsequent delete command deleted the orignal volume because the "path
> uuid" for original volume and new volume is maintained with same uuid
> temporarily.
> *** Either we shouldn't let user fire migrateVolume API with storageId if the
> volume's original storageId and destStorageId are same.
> (OR)
> *** we should use a unique path UUID so that in case of copy command failure,
> it will only delete the new volume.
