This section tells how to set up NFS shares for primary and secondary storage on the same node with the Management Server. This is more typical of a trial installation, but is technically possible in a larger deployment. It is assumed that you will have less than 16TB of storage on the host. The exact commands for the following steps may vary depending on your operating system version. On RHEL/CentOS systems, you'll need to install the nfs-utils package: $ sudo yum install nfs-utils On the Management Server host, create two directories that you will use for primary and secondary storage. For example: # mkdir -p /export/primary # mkdir -p /export/secondary To configure the new directories as NFS exports, edit /etc/exports. Export the NFS share(s) with rw,async,no_root_squash. For example: # vi /etc/exports Insert the following line. /export *(rw,async,no_root_squash) Export the /export directory. # exportfs -a Edit the /etc/sysconfig/nfs file. # vi /etc/sysconfig/nfs Uncomment the following lines: LOCKD_TCPPORT=32803 LOCKD_UDPPORT=32769 MOUNTD_PORT=892 RQUOTAD_PORT=875 STATD_PORT=662 STATD_OUTGOING_PORT=2020 Edit the /etc/sysconfig/iptables file. # vi /etc/sysconfig/iptables Add the following lines at the beginning of the INPUT chain where <NETWORK> is the network that you'll be using: -A INPUT -s <NETWORK> -m state --state NEW -p udp --dport 111 -j ACCEPT -A INPUT -s <NETWORK> -m state --state NEW -p tcp --dport 111 -j ACCEPT -A INPUT -s <NETWORK> -m state --state NEW -p tcp --dport 2049 -j ACCEPT -A INPUT -s <NETWORK> -m state --state NEW -p tcp --dport 32803 -j ACCEPT -A INPUT -s <NETWORK> -m state --state NEW -p udp --dport 32769 -j ACCEPT -A INPUT -s <NETWORK> -m state --state NEW -p tcp --dport 892 -j ACCEPT -A INPUT -s <NETWORK> -m state --state NEW -p udp --dport 892 -j ACCEPT -A INPUT -s <NETWORK> -m state --state NEW -p tcp --dport 875 -j ACCEPT -A INPUT -s <NETWORK> -m state --state NEW -p udp --dport 875 -j ACCEPT -A INPUT -s <NETWORK> -m state --state NEW -p tcp --dport 662 -j ACCEPT -A INPUT -s <NETWORK> -m state --state NEW -p udp --dport 662 -j ACCEPT Run the following commands: # service iptables restart # service iptables save If NFS v4 communication is used between client and server, add your domain to /etc/idmapd.conf on both the hypervisor host and Management Server. # vi /etc/idmapd.conf Remove the character # from the beginning of the Domain line in idmapd.conf and replace the value in the file with your own domain. In the example below, the domain is company.com. Domain = company.com Reboot the Management Server host. Two NFS shares called /export/primary and /export/secondary are now set up. It is recommended that you test to be sure the previous steps have been successful. Log in to the hypervisor host. Be sure NFS and rpcbind are running. The commands might be different depending on your OS. For example: # service rpcbind start # service nfs start # chkconfig nfs on # chkconfig rpcbind on # reboot Log back in to the hypervisor host and try to mount the /export directories. For example (substitute your own management server name): # mkdir /primarymount # mount -t nfs <management-server-name>:/export/primary /primarymount # umount /primarymount # mkdir /secondarymount # mount -t nfs <management-server-name>:/export/secondary /secondarymount # umount /secondarymount
