Title:
attachVolume fails with HTTP 500 on PreSetup (DatastoreCluster) pool -
VirtualMachineMO.attachDisk uses vCenter HTTP folder browser which doesn't
work for DatastoreCluster datastores
Component: Storage, VMware
CloudStack Version: 4.22.0
Description:
When attaching a detached volume (state=Ready) to a VM (even Stopped) where
the volume resides on a PreSetup/DatastoreCluster-type primary storage pool,
attachVolume fails with:
java.io.IOException: Server returned HTTP response code: 500 for URL:
https://vcenter.../folder/i-XXXX-XX-VM%2F<vmdkpath>.vmdk
?dcPath=<DC>&dsName=<DatastoreCluster>
at VirtualMachineMO.attachDisk(VirtualMachineMO.java:1458)
Root Cause:
VirtualMachineMO.attachDisk() calls getVmdkFileInfo() which performs an
HTTP GET to vCenter's /folder/ datastore browser endpoint to determine
VMDK capacity. This HTTP endpoint returns HTTP 500 for DatastoreCluster
(poolType=PreSetup) datastores — vCenter does not support HTTP-based file
browsing for DatastoreCluster paths.
The fix should use vSphere API queryVirtualDiskInfo() instead of HTTP
datastore browser to retrieve VMDK metadata for PreSetup pool types.
Steps to Reproduce:
1. Add a PreSetup/DatastoreCluster primary storage pool (poolType=PreSetup)
2. Create or migrate a detached data volume to that pool
3. Attempt cmk attachVolume id=<vol-uuid> virtualmachineid=<vm-uuid>
(fails whether VM is Running or Stopped)
Expected: Volume attaches successfully
Actual: HTTP 500 from vCenter, attach fails
Environment:
- CloudStack 4.22.0
- VMware vCenter (vcenter.opscloud.eumetsat.int)
- Primary storage type: DatastoreCluster (poolType=PreSetup)
- ESXi hosts: tcebld* cluster
Workaround: None within CloudStack currently.
