rsync error: protocol incompatibility

ERROR: rsync error: protocol incompatibility (code 2) at compat.c(171) [sender=3.0.6]

I use rsync with ssh and authorized key files for auto login to mirror a remote system to the local one.The only change I made was on my .bashrc on the remote end I added in some commands to show file system usage. do a du -f and a tail of the log on login for conveniences.

My assumption here is that when rsync executes the ssh to connect it received 'junk'. Once I removed the extra output from the .bashrc file on the remote end, it worked just fine.SO check your remote end for .profile, .bashrc, .bash_profile etc.... any scripts running that add extra output on login.

logrotate not working

When default log rotate is not working we need to check its configuration using command

/usr/sbin/logrotate -f /etc/logrotate.conf

and try running a selected configuration using

logrotate -fd /etc/logrotate.d/test

where test is the configuration file name.

Openstack Icehouse install Part -7 Cinder Service Block storage

Install Cinder- Block Storage Service

On Controller Node
Install the appropriate packages

yum install openstack-cinder -y

Configure Block Storage to use your database

openstack-config --set /etc/cinder/cinder.conf database connection mysql://cinder:cinder4admin@controller/cinder

Creating Database
On Mysql Server

mysql -u root -p

CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'cinder4admin';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'10.1.15.30' IDENTIFIED BY 'cinder4admin';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'cinder4admin';

exit;

Create the database tables

su -s /bin/sh -c "cinder-manage db sync" cinder

Create a cinder user.

keystone user-create --name=cinder --pass=cinder4admin --email=cinder@example.com
keystone user-role-add --user=cinder --tenant=service --role=admin

Edit the /etc/cinder/cinder.conf configuration file:

openstack-config --set /etc/cinder/cinder.conf DEFAULT auth_strategy keystone
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_uri http://controller:5000
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_host controller
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_protocol http
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_port 35357
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_user cinder
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_tenant_name service
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_password cinder4admin

Configure Block Storage to use the Qpid message broker:

openstack-config --set /etc/cinder/cinder.conf DEFAULT rpc_backend cinder.openstack.common.rpc.impl_qpid
openstack-config --set /etc/cinder/cinder.conf DEFAULT qpid_hostname 10.1.15.40

Register the Block Storage service with the Identity service so that other OpenStack services can locate it:

keystone service-create --name=cinder --type=volume --description="OpenStack Block Storage"
keystone endpoint-create --service-id=$(keystone service-list | awk '/ volume / {print $2}') --publicurl=http://controller:8776/v1/%\(tenant_id\)s --internalurl=http://controller:8776/v1/%\(tenant_id\)s --adminurl=http://controller:8776/v1/%\(tenant_id\)s

Register a service and endpoint for version 2 of the Block Storage service API:

keystone service-create --name=cinderv2 --type=volumev2 --description="OpenStack Block Storage v2"
keystone endpoint-create --service-id=$(keystone service-list | awk '/ volumev2 / {print $2}') --publicurl=http://controller:8776/v2/%\(tenant_id\)s --internalurl=http://controller:8776/v2/%\(tenant_id\)s --adminurl=http://controller:8776/v2/%\(tenant_id\)s

Start and configure the Block Storage services to start when the system boots:

service openstack-cinder-api start
service openstack-cinder-scheduler start
chkconfig openstack-cinder-api on
chkconfig openstack-cinder-scheduler on

On Cinder Service Node.

Setting Up NFS Share .

Installing NFS packages
yum install nfs-utils nfs-utils-lib

Make and configure partition
mkfs.ext4 /dev/mapper/vg_cloud2-LogVol03
mkdir /home/cinder_nfs
