What does "showmount.update.failed" message mean?

Applies to

ONTAP 9

Answer

• "showmount.update.failed" message means that failure happened to update exports.data file.

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
