[Gluster-users] HA with nfs-ganesha and Virtual IP

2017-01-23 Thread David Spisla 
Hello,

I have two ec2-instances with CentOS and I want to create a cluster 
infrastructure with nfs-ganesha, pacamaker and corosnyc. I read different 
instructions but in some points I am not really sure how to do.
At the moment my configuration is not running. The system says:

Enabling NFS-Ganesha requires Gluster-NFS to be disabled across the trusted 
pool. Do you still want to continue?
(y/n) y
This will take a few minutes to complete. Please wait ..
nfs-ganesha : success

But nothing happen. Ganesha is not starting. I think there is a problem with my 
ganesha-ha.conf file.


1.  What about that Virtual IPs? How I can create them (maybe /etc/hosts) 
???

2.  Should I use always use the same ganesha.ha.conf file on all nodes or 
should I change entries. You can see as follows my two ganesha.ha.conf files

First ec2-instance:
# Name of the HA cluster created.
# must be unique within the subnet
HA_NAME="ganesha-ha-360"
#
# The gluster server from which to mount the shared data volume.
HA_VOL_SERVER="ec2-52-209-xxx-xxx.eu-west-1.compute.amazonaws.com"
#
# N.B. you may use short names or long names; you may not use IP addrs.
# Once you select one, stay with it as it will be mildly unpleasant to
# clean up if you switch later on. Ensure that all names - short and/or
# long - are in DNS or /etc/hosts on all machines in the cluster.
#
# The subset of nodes of the Gluster Trusted Pool that form the ganesha
# HA cluster. Hostname is specified.
HA_CLUSTER_NODES="ec2-52-209-xxx-xxx.eu-west-1.compute.amazonaws.com,ec2-52-18-xxx-xxx.eu-west-1.compute.amazonaws.com"
#HA_CLUSTER_NODES="server1.lab.redhat.com,server2.lab.redhat.com,..."
#
# Virtual IPs for each of the nodes specified above.
VIP_ec2-52-209-xxx-xxx.eu-west-1.compute.amazonaws.com="10.0.2.1"
VIP_ec2-52-18-xxx-xxx.eu-west-1.compute.amazonaws.com="10.0.2.2"
#VIP_server1_lab_redhat_com="10.0.2.1"
#VIP_server2_lab_redhat_com="10.0.2.2"

Second ec2-instance:
# Name of the HA cluster created.
# must be unique within the subnet
HA_NAME="ganesha-ha-360"
#
# The gluster server from which to mount the shared data volume.
HA_VOL_SERVER="ec2-52-18-xxx-xxx.eu-west-1.compute.amazonaws.com"
#
# N.B. you may use short names or long names; you may not use IP addrs.
# Once you select one, stay with it as it will be mildly unpleasant to

#
# The subset of nodes of the Gluster Trusted Pool that form the ganesha
# HA cluster. Hostname is specified.
HA_CLUSTER_NODES="ec2-52-18-xxx-xxx.eu-west-1.compute.amazonaws.com,ec2-52-209-xxx-xxx.eu-west-1.compute.amazonaws.com"
#HA_CLUSTER_NODES="server1.lab.redhat.com,server2.lab.redhat.com,..."
#
# Virtual IPs for each of the nodes specified above.
VIP_ec2-52-209-xxx-xxx.eu-west-1.compute.amazonaws.com="10.0.2.1"
VIP_ec2-52-18-xxx-xxx.eu-west-1.compute.amazonaws.com="10.0.2.2"
#VIP_server1_lab_redhat_com="10.0.2.1"
#VIP_server2_lab_redhat_com="10.0.2.2"

You can't just make them up. In your case you must get them from somewhere in 
AWS so that you don't have a conflict with other AWS users.

("Virtual" is a bad name. They're real IPs, and they are managed by pacemaker.)

You only need to create the ganesha-ha.conf (note the '-') once, on one host, 
namely the same host you issue the gluster commands. Gluster will propagate it 
to the other nodes in the cluster.
