[swarm] step 'Create filesystem and mount volume' wasn't execute completely, no error message present

[Tatyana Kuterina]

Detailed bug description:
Found on CI:
https://product-ci.infra.mirantis.net/job/9.x.system_test.ubuntu.ceph_ha_one_controller/36/console

Test: Check VM backed with ceph migration in ha mode with 1 controller
Test Group: migrate_vm_backed_with_ceph

Steps to reproduce:
        1. Create cluster
        2. Add 1 node with controller and ceph OSD roles
        3. Add 2 nodes with compute and ceph OSD roles
        4. Deploy the cluster
        5. Check ceph status
        6. Run OSTF
        7. Create a new VM, assign floating ip
        8. Migrate VM
        9. Check cluster and server state after migration
        10. Terminate VM
        11. Check that DHCP lease is not offered for MAC of deleted VM
        12. Create a new VM for migration, assign floating ip
        13. Create a volume and attach it to the VM
        14. Create filesystem on the new volume and mount it to the VM
        15. Migrate VM
        16. Mount the volume after migration
        17. Check cluster and server state after migration
        18. Terminate VM

Expected results:
   Deploy is finished without errors.
   step 14: <<< 14. Create filesystem on the new volume and mount it to the VM >>>

Description of the environment:

 9.1 snapshot #169

[Tatyana Kuterina (tkuterina)]

Issue is reproduced on 9.1 snapshot #173.
Instance, which was created in CI test, is up and active, but it is impossible to ping it by its ips.
If create instance manually with the same flavor, image, security group and network, ping is successful.

Fresh failure: https://product-ci.infra.mirantis.net/job/9.x.system_test.ubuntu.ceph_ha_one_controller/38/console

Now against 'migrate_vm_backed_with_ceph' test. Unable to mount volume after VM migration.

9.1 snapshot #177

[Vitaly Sedelnik (vsedelnik)]

Fuel QA team, please reproduce the issue and provide diagnostic snapshot

[Timur Nurlygayanov (tnurlygayanov)]

Could you please attach diagnostic snapshot to the issue?
