Specifying MDS Servers Manually

If you cannot configure the DNS records in your network, you need to manually specify the IP addresses of all running MDS servers in the cluster each time you do any of the following:

• Set up a new MDS server in a cluster (except for the first MDS server). For details, see Adding MDS Servers .
• Set up a new chunk server to a cluster. For details, see Setting Up Chunk Servers .
• Set up a new client for a cluster. For details, see Setting Up Clients .

To specify the IP address of an MDS server manually, create the bs.list file in the /etc/pstorage/clusters/ Cluster_Name directory (make this directory if it does not exist) on the server you are configuring for the cluster and specify in it the IP address and port to use for connecting to the MDS server. For example:

# echo "10.30.100.101:2510" >> /etc/pstorage/clusters/pcs1/bs.list

# echo "10.30.100.102:2510" >> /etc/pstorage/clusters/pcs1/bs.list

This command:

1. Assumes that you are configuring discovery for the pcs1 cluster (thus, the directory name of /etc/pstorage/clusters/pcs1 ).
2. Creates the /etc/pstorage/clusters/pcs1/bs.list file on the server, if it did not exist before.
3. Adds the information on two MDS servers with IP addresses 10.30.100.101 and 10.30.100.102 to the bs.list file.
