[Gluster-users] glusterfs on Microsoft Azure?

[Aki Ketolainen]

Hi,

Replying to the gluster-users list with a solution to this problem.

Our VMs are under 4 different Azure subscriptions in separate virtual networks.
VMs under these subscriptions are unable to ping each other, 
thus unable to be a part of a Gluster cluster or be a Gluster client.

Mr. Tom Wu has written a Powershell script to connect Azure virtual
networks under different Azure subscriptions. 

https://tombwu.wordpress.com/2015/07/02/build-complex-cross-azure-subscription-windows-lab-by-using-azure-site-to-site-vpn/

This solved my problem completely. The throughput to the Glusterfs client is approx. 100 Mbps
with the basic Azure VPN gateway. There is a high performance VPN gateway but it costs about 8€ per day.

One thing that was missing from Tom's blog post was how the Azure Powershell authentication is done.
This needs to be set in Azure Powershell session with Get-AzurePublishSettingsFile and Import-AzurePublishSettingsFile.

Hi,

I was trying to setup glusterfs 3.7.4-2 on CentOS 6.7 on Microsoft Azure.
We are fortunate to receive service from Microsoft Bizspark program for startups.
Unfortunately, we are forced to run the virtual machines on separate Azure accounts.
This in turn causes the VM's not being able to ping each other.

Reading the gluster documentation at http://gluster.readthedocs.org/en/latest/Install-Guide/Configure/
it says "For the Gluster to communicate within a cluster either the firewalls
have to be turned off or enable communication for each server."

In my case this is impossible because the VM's under different Azure accounts are unable to
ping each other. This restriction is a design choice Microsoft has made. The needed glusterfs 
service ports are open between the VM's.

What could be a remedy to this problem?

Here's detailed information about my setup:

(on hostA)
# gluster peer status
Number of Peers: 1

Hostname: hostB.domain
Uuid: 7e468940-97e5-4595-a835-5eeedae07770
State: Peer in Cluster (Connected)

(on hostB)
# gluster peer status
Number of Peers: 1

Hostname: hostA.domain
Uuid: 1a5a62a8-4e08-4f06-9f5d-e159a2f7e5c9
State: Peer in Cluster (Connected)

(on hostA)
# gluster volume create home replica 2 hostA.domain:/data/home/gv0 hostB.domain:/data/home/gv0
volume create: home: failed: Host hostA.domain is not in 'Peer in Cluster' state

(/var/log/glusterfs/etc-glusterfs-glusterd.vol.log)
