FILE_DS datastore not working

Hi again,

FILE_DS functionality is not working. I am using the latest release (0.9.3) of the addon. The documentation states states it should work... "Linstor driver can also be used as a system/context datastore," but the example is only for a SYSTEM_DS.

Steps to reproduce:

  1. Create linstor image datastore and system datastore according documentation. VM instantiation (tty linux from ONE Marketplace) works fine.
  2. Create linstor file_ds datastore from the following template:
    NAME="hci-file_ds_linstor_a2"
    DS_MAD="linstor"
    TYPE="FILE_DS"
    TM_MAD="linstor"
    LINSTOR_AUTO_PLACE="2"
    LINSTOR_STORAGE_POOL="filauto2copy"
    BRIDGE_LIST= "srv362 srv363 srv364"
  3. Upload a testfile to this file_ds datastore works fine
  4. Adding the test file to the VM Template (Context -> Files) and instantiate produces following error in oned.log

This is a misunderstanding, the FILE_DS isn't described on how to create, nor is it in any way tested as you noticed.

Yes, I thought, as it is not 100% clear, to give it a shot and report back.
When it is ready I can test again...

Hi,
just wanted to kindly ask, if implementing FILE_DS is on your roadmap? Because this is hindering us to use linstor for our production OpenNebula environment.
Thanks

Very bluntly put: Make LINBIT want to do this feature. I.e. become a LINBIT customer

Fair enough, will come back to you then through business channels.
