Steps to reproduce:
1. Deploy cluster:
Ubuntu HA, GRE, Ceph for images, Sahara, 3 Controllers, 1 Compute, 1Cinder, 2Cephs
2. Add and register image according this guide http://docs.mirantis.com/openstack/fuel/fuel-5.0/operations.html#preparing-sahara-for-testing
3. Run OSTF test "Sahara tests to create, list, start, checks and delete cluster"

Expected result: Test pass

Actual result: Test failed on the step:
"5. Send request to launch cluster"

In order to run Platform Sahara test a compute node must have 4 GB RAM at least.

[Dmitry Mescheryakov (dmitrymex)]

Egor, we are going to raise the minimum memory requirement to 4 GB in the fix for the following bug: https://bugs.launchpad.net/fuel/+bug/1334700/comments/4

Once fixed, OSTF will not allow to run tests on environments with computes having to low RAM

[Egor Kotko (ykotko)]

It is weird behaviour I have add RAM on compute node till 8 GB. Fuel get that update.
The test was fail again. After some time the test was restarted and it was pass.

i have 64GB ram on my compute node. but still i am facing this issue. the logs are present on the link below

[Yaroslav Lobankov (ylobankov)]

It is not a good idea to use Sahara when compute nodes are virtual machines. It will be better if you use real hardware (a compute node must have 4 GB RAM at least).

[Yaroslav Lobankov (ylobankov)]

Abdul Hannan, could you please provide us with Sahara logs from all three controllers?
