Answer

Example:

[xxx: mgwd: showmount.update.failed:error]: Flushing to exports.data file failed on Vserver <vserver_name> 

  • The corrective action is to verify that the root volume of the Vserver is online and not full.

The specific procedure is below.

  1. Execute "vserver show -vserver <vserver_name> -fields rootvolume" command.to find the root volume name

    Example:

    Cluster::> vserver show -vserver testsvm -fields rootvolume
    vserver rootvolume
    ------- ----------
    testsvm vol0

  2. Execute "volume show -vserver <vserver_name> -volume root_volume_name> -fields state" command to check the root volume is online

    Example:

    Cluster::> volume show -vserver testsvm -volume vol0 -fields state
    vserver volume state
    ------- ------ ------
    testsvm vol0   online

  3. Execute "df -V -vserver <vserver_name> -volume <root_volume_name>" to confirm that the volume usage rate is not Full

    Example:

    Cluster::> df -V -vserver testsvm -volume vol0 -fields percent-used-space
    vserver volume fs-type percent-used-space
    ------- ------ ------- ------------------
    testsvm vol0   active  0%
    testsvm vol0   snapshot
                           25%
    2 entries were displayed.

In the above example, the root volume is vol0, and percent-used-space is 0% this means it's not full.

Additional Information

  • The exports.data file is for providing a list of exported volumes/qtrees to clients  running the "showmount -e" command.
  • This file can be flushed for the following reasons.
  1. Execute update internal cache process in background on ONTAP data management software®
  2. Execute "showmount -e" command from client-side
