Making or Unmaking a File System

Chapter 6 Managing the File System

Managing File System Operations

subsequent machines listed serve as backup coordinators. To create redundancy, it is recommended that you list two machines. Typically, the selected systems are also configured for FSM services, but this is not a requirement.

If the fsnameservers file does not exist, then the file system operates as a local file system, requiring both a client and a server. The file system will not communicate with any other StorNext File System product on the network, thus eliminating the sharing of the FSS over the SAN.

Caution: It is extremely important that all copies of /usr/cvfs/config/ fsnameserver file in a SAN be identical. A stale configuration on a system that is not in use can cause election problems if fsmpm processes are running with mismatched fsnameservers.

It is also critical to verify that complete network connectivity exists between all systems running SNFS (client or server). This is important because all StorNext systems participate in the failover process.

After you type the IP addresses of two reliable machines on your network in the fsnameservers file, copy the fsnameservers file to every machine running SNFS. After changing the fsnameservers file, always restart (stop and start) all file system services running on the SNFS.

Redundant NICs are supported in the fsnameservers file; simply list both NIC addresses in the file.

Use the following procedures to make or re-make a file system.

Caution: This task destroys all existing data for the selected file system and creates a new configuration. Making or re- making a file system results in a complete loss of user data.

After remaking a managed file system, you must delete or recreate the relation points.
