openstack network create command gives "The Keystone service is temporarily unavailable" and "The server is currently unavailable"

Currently, we are trying to setup neutron for our cloud server. Since everyone is new to this, we are struggling a bit. When we entered this command:
openstack network create --share --external \
--provider-physical-network provider \
--provider-network-type flat provider
And it throws this error:
Error while executing command: HttpException: 503, The Keystone service is temporarily unavailable.: 503 Service Unavailable: The server is currently unavailable. Please try again at a later time.
We are following openstack docs guide to a T.
Does anyone know what causes this error and how to fix it?
Thanks.
I fixed it, it was a problem with MariaDB. When we updated it from 10.1 to 10.3, I couldn't access my DB, so when I fixed that error it works now.

OpenStack VM File System Error on reboot and nova rescue Cannot rescue a volume-backed instance (HTTP 400)

Openstack VM's File system went into read-only mode and rebooted it. After the reboot I'm getting grub menu and auto booting from the Kernel and seeing only blank screen in Openstck dashboard console.
I tried nova rescue but failed with below error,
cannot be rescued: Cannot rescue a volume-backed instance (HTTP 400)
I did edited the grub and enetered single/rescue mode to fix the file system error but still I'm getting blank screen after ctrl+x in grub edit.
I want to bring up the vm instance and how do I fix the file system error.
File system error happened as of vm's backend storage, ceph sds node's all went down as of power failure and restored back.
I'm using RHOSP 13 and VM's image is RHEL 7.
I did alternate way to get into rescue mode and fixed the file system error.
ssh to compute Host of the instance and attach ISO image to the instance as it's backend is KVM (inside the file point the cdrom to ISO image location and boot dev to cdrom using virsh edit)
virsh edit vmname
Make the instance to active state from openstack cli command
nova reset-state --active instancename
Start the VM from compute Host
virsh start vmname
Get into openstack dashboard console and repair the file system accordingly and shutdown the instance
Troubleshooting
Rescue mode
continue to shell
vgscan -v
vgchange -a y
lvscan
e2fsck /dev/xxx or xfs_repair /dev/xxx
From openstack cli start the instance normally after file system fix
nova start instancename

Keystone error 401 output to every command/Keystone don't know Default Openstack Domain

I am currently trying to install Openstack for the first time.
I followed the installation guide given by Openstack (here)
The basic setup is done , and I am now trying to install the four "basic" services of Openstack : Keystone, Glance , Nova and Neutron.
But I have an error with Keystone , I followed the tutorial , but when I am trying to test Keystone , by launching even the simplest command (openstack role create myrole for example)
I have the following message
The request you have made requires authentication. (HTTP 401) (Request-ID: req-e9164787-381f-4f69-af7f-7ea4932c3a0b)
You can find here all the command I previously entered here , here is the command openstack domain list --debug output and here the Keystone.log
As you can see in the keystone.log , I have the message
2019-01-16 20:45:53.064 7056 WARNING keystone.auth.core [req-fd1b7466-cf24-406f-82ce-2549156ae4d6 - - - - -] Could not find domain: default.: DomainNotFound: Could not find domain: default.
It seems that Keystone do not know the Default Domain , how can I change that.
I have already tried "Default" and "default' (with and without the lower-case) , but no change.
I cannot even create another domain , or create a Token (I read on other thread that it might be the problem source)
Let me know if you need anything more , and thanks in advance !

bootstrap clodufiy3.4 error occured

I installed cloudify3.4 according to the cloudify DOCS. When I install the manager, and executed like this:
# cfy bootstrap --install-plugins -p openstack-manager-blueprint.yaml -i openstack-manager-blueprint-inputs.yaml
an error occurred:
[ERROR] Workflow failed: Task failed 'fabric_plugin.tasks.run_script' -> Timed out trying to connect to 192.168.17.15 (tried 5 times)
I have already build a extern network 192.168.17.0/24 and I have already installed
cloudify_docker_plugin-1.3.2-py27-none-linux_x86_64-Ubuntu-trusty.wgn
cloudify_fabric_plugin-1.4.1-py27-none-linux_x86_64-centos-Core.wgn

cloudify_openstack_plugin-1.4-py27-none-linux_x86_64-redhat-Maipo.wgn
So, how to solve this error? Thank you to everyone who helped me!
It seems that you can't connect the manager.
Please make sure that you have an ssh connection from the CLI to the manager.
Since you are bootstrapping an Openstack manager you should make sure to have an external IP if you are outside of Openstack or that the CLI is on the same network if you are on Openstack.

opensuse network management undefined

I did an update on my opensuse box and networking stopped working. The system is trying to use networkmanager, even though it isn't installed. I am using yast to try and get it to use ifup, but it complains about no network connection. I tried running:
ifup eth0
and I get back:
Network is managed by '' -> skipping
Does anyone out there know why it is coming back empty and if there is a config file that I can manually tweak to fix this?
I'm assuming you are running 12.3 or 13.1 with systemd.
Disable network manager if it exists:
systemctl disable networkmanager.service
Enable network.service:
systemctl enable network.service
Make sure ifcfg-eth0 exists with a configuration in /etc/sysconfig/network/
Run ifup eth0
Hope this will help someone.
1. Disable NetworkManager, Stop is and then enable it and restart it respectively.
2. All this happens in console. Check the status for NetworkManager and in the status messages it should show that the interface(wierless) is disconnected. Confirm this by typing command "sudo nmcli c"
3. Type command "sudo iwlist (wireless-interface) scan" to show you the available wireless networks
4. If you see the network that you want to connect to listed, type command "nmcli a" and enter the corresponding connect phrase/password to connect
