i am new to clustering, i want to practice clustering on centos.
i m using vmware workstation v6.
i have installed three centOS VM 500mb ram each.
i am following all docs from centos site but geeting more confuse as those are advance one.
so please tell me.
>can clustering can be done on vmware?
>what should be the fencing device?
>while using conga it's asking for fully qualified domain name, does it required?
>can i direct start to make a cluster or do i need to learn to make gfs,clvm before?
>how a single hardware drive can be share by all VMs.
if anyone has proper steps to configure cluster on VM please share with me.
There are 4 types of clustering setup in Linux
Storage - with GFS
High Availability - single point of failure
Load balance - load balance through LVS
High performance - allow application work parallel
1.Yess. you can setup such testing environment using Vmeare.
2.At virtual environment you dont need fencing device just define it as manual devices.
3.Not necessary you can access through localhost.
4.Yess directly you can configure high availability cluster environment, gfs is a file system even you can have some other file systems if you need.
5.what hardware drive that you want to share?
first you configure one node and safe the same configuration to all other nodes
can you please tell me the procedure to setup a common storage area by using iscsi on vmware.
as i am trying clustering on vmware test environment.
now i configured ethernet bonding on all my three VM's.
i configure bond0 on eth0 & eth1. same for all machines following procedure in guide "https://www.redhat.com/docs/manuals/...owse/rh-cs-en/"
in starting everything was fine ,all VMs were pinging properly.
but after rebooting, i donno wt happen all three are not pinging.
so please tell me wt can be the issue with bonding.
also i have configured cluster but while starting cluster m/m tool
system-config-cluster it gives an error "an err was encountered while reading conf file click ok to create new conf. click ok to continue anyway"
herewith i am attaching 2 images from there i hope you can get some right idea.
if your cluster started sucessfully then only 2nd tab "cluster managements" will appear at system-config-cluster(cluster configuration window) and all of your cluster nodes added on the cluster environment.
