[Gluster-users] glusterfs on Microsoft Azure?

[Aki Ketolainen]

Hi,

I've ensured that both forward and reverse DNS queries work for these two hosts
(using dnsmasq together with the /etc/hosts file).

Best regards,

Aki

Can you configure your /etc/hosts file to include these hostnames along with their IPs? That should solve your problem I guess.

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)
