Description Elad 2017-08-22 14:31:23 UTC 
Created attachment 1316663 [details]
logs from host and engine

Description:
Querying for VM lease while the lease is being created with a "NoSuchLease: No such lease" failure, because the lease is in the creation process, will cause the create_lease task to get stuck on state 'finished' on SPM.
This causes the storage pool to get flapping between up and non-responsive in a severl seconds frequency.

The bug seems to be on engine which not ordering SPM to clear the create_lease task.

How reproducible:
Reproduces always during execution of https://polarion.engineering.redhat.com/polarion/redirect/project/RHEVM3/workitem?id=RHEVM-17624

Steps to Reproduce:
1. Create a VM with a lease on the storage (NFS in my case) and during the creation, try to remove the lease (via REST)

Actual results:

lease_info fails with the following because the lease has not been created yet:

After that, the create_lease task will be stuck in state 'finished' in SPM which causes the whole storage pool to change states between up and non-responsive every few seconds.

Expected results:

Workaround:
Restart ovirt-engine service

Elad, 
Can you please add the REST-API call which removes the lease.
Comment 2 Eyal Shenitzky 2017-12-31 07:37:22 UTC 
Also, 
There are no logs in the attached file.
Can you please add the relevant logs?

I think I managed to reproduce by removing the lease via REST [1] during its creation

As you wrote, this is an error which suggests that the request you sent to the engine isn't valid:

This error is not related to the removal of the lease.
Comment 5 Elad 2017-12-31 15:59:49 UTC 
Could not reproduce the original scenario (remove lease AFTER its creation). 
Executed the mentioned automation job (from the bug description) several times, all passed.

Used:
rhvm-4.2.0.2-0.1.el7.noarch
Comment 6 Eyal Shenitzky 2018-01-03 08:05:33 UTC

Can you please close the bug?

Happened again during automation execution.

This error is expected due to the latest optimization in the VM leases flow.
Before creating new lease the engine verifies that the lease doesn't already exist.

So this isn't the reason for the 'Unknown' situation.

You can see later that the operation for creating the lease initiated:
