Cannot schedule VM, there is no suitable system ds

Dmitry1 · September 22, 2016, 5:24pm

Hello, I can’t understand why datastore cannot be applied for VM, VM is in pending state:
Persistent or not, doesn’t matter.
Resources should be enough.

You can get a more detailed information from the scheduler by increasing
the log level in sched.conf. It is most likely that there are conflicting
cluster requirements etc…

Can anyone help with this problem?

ruben · September 26, 2016, 12:36pm

The common reasons are:

You have a cluster and did not added a system ds to the cluster
The cluster is not being monitored

Dmitry1 · September 26, 2016, 12:40pm

On this cluster - some files created already.

/var/lib/one/datastores/109/

How can I debug that?

ruben · September 26, 2016, 12:42pm

onecluster list, will show you the clusters you have

onecluster show <cluster_id> will show the vnets and ds associated to a
given cluster

I don’t see any problems with it, what to do next?

atodorov_storpool · October 6, 2016, 2:26pm

Hi,

Judjing by the image that you have posted the system datastore is disabled. Please enable the SYSTEM datastore and it will deply the VMs. In sunstone: Storage -> Datastores -> select the SYSTEM datastore (0). There is a button with three vertical dots and triangle pointing down. Click there and select Enable.

Kind Regards,
Anton Todorov

Dmitry1 · October 6, 2016, 2:30pm

But I want to place it on datastore 109, and Image for VM is assigned to this datastore.

atodorov_storpool · October 6, 2016, 3:17pm

The image behavior is depending on the technology behind the datastore, the TM_MAD in use for both image and system datastores and so on. The system datastore is needed for the VM to work.

For your use case you should select a datastore technology and TM_MAD that are of shared type. Then the TM_MAD will create symlink to the image in the image datastore instead of placing the file in the SYSTEM one.

Kind Regards,
Anton Todorov

Dmitry1 · October 6, 2016, 3:57pm

Thank you! It works!
