StorNext: Resolving when a StorNext File System Client Fails to Mount a StorNext File System

StorNext: Resolving When a StorNext File System Client Fails to Mount a StorNext File System


Symptom:
On a StorNext or StorNext FX system, you receive the following error:

mount.cvfs: Can't mount filesystem 'FILESYSTEMNAME'.
Check system log for details. Invalid argument


Cause:
The system cannot resolve the IP address or hostname defined in the fsnameservers file.

Resolution:
Use this procedure to troubleshoot this problem.



  1. Find the failure reported in the file install_path/debug/nssdbg.out.

    ERR NSS: Establish Coordinator failed GetHostByName of '[HOST01]'
    (No such file or directory)
    INFO NSS: Primary Name Server is 'HOST01' (unknown IP)
    ERR NSS: Establish Coordinator failed GetHostByName of '[HOST02]'
    (No such file or directory)
    INFO NSS: Secondary #1 Name Server is '[HOST02]' (unknown IP)


  2. If it is similar to the events reported above, then please check the file fsnameservers for proper setup.

    The file is located in the following directory, depending upon the product and operating system:

    • Windows StorNext File System 2.x: C:\SNFS\config

    • Windows StorNext File System 3.x: C:\Program Files\Stornext\config

    • Linux or UNIX: /usr/cvfs/config

    For this example, the hostname definition line was set up incorrectly:

    # Primary FS Name Sserver is rock # HOST01#
    # Secondary FS Name Server
    #1 is crag
    # [HOST02]

    The fsnameservers file should contain the name of the IP address or hostname to use as either a primary or a secondary coordinator. The use of IP addresses is preferred to avoid problems associated with lookup system (DNS or NIS) failures.

    The format of an fsnameservers file line is either:
    IP_address or HOSTNAME


  3. Correct the fsnameservers file like below:

    host01
    host02
