Hi,
Thanks for the reply ,.
I have one doubt at the Export given in the installation doc .
I.e
*Export /srv/cloud to all the cluster nodes. For example, if you have all
your physical nodes in a local network with address 192.168.0.0/24 you will
need to add to your /etc/exports file a line like this: *
* *
*$ cat /etc/exports
/srv/cloud 192.168.0.0/255.255.255.0(rw)*
* *
* In each cluster node create /srv/cloud and mount this directory from the
front-end*.
Here what does mounting exactly meant , is it required to mount /srv/cloud
on to the host system from the from end system ..?
