Troubleshooting client performance problems

Use the information in this topic to troubleshoot problems that you are having with client performance.

Problem

A client is timing out or taking an unusually long time to access data.

Perform the following steps to resolve the problem:
  1. Verify that the metadata server managing the fileset being accessed is active. List the filesets to view the server to which the fileset being accessed is attached, the quota percentage and type, the attach point, and the directory.
    • From the administrative command-line interface (CLI), run the sfscli lsfileset command.
    • From the SAN File System console, click Manage Servers and Clients > Filesets.
  2. Verify that the master metadata server is active. Attempt to access the master metadata server through either the SAN File System console or the administrative command-line interface. If you cannot, suspect one of the following:
    • The master metadata server is down. See Troubleshooting the cluster.
      Tip: The administrative agent automatically attempts to restart a metadata server that fails for any reason. Therefore, if you cannot access a metadata server, wait a few minutes and try again to ensure that it is not in the process of restarting.
    • There is an IP network problem between the client and the cluster. See Isolating problems with the SAN File System.
