Unable to create large VTL on Linux

 

Description

When creating a Large_VTL on a Linux machine, the NetVault WebUI takes too long to respond and the session expires.

Symptom

On a Linux NetVault Server, when creating a Large_VTL, if the WebUI times out due to inactivity or the user closes the WebUI while the creation is still in progress, the VTL creation does not occur.

Solution

In the WebUI, add a VTL using the Re-add previously generated virtual device option.

 
* 
NOTE: This solution works only when the VTL entry is present in the "diskdevice.cfg" file under "libraries" section and when the directory is present in the mentioned path.

Browsing a folder with a large number of files times out

Description

During a restore, browsing and expanding a folder with a large number of files, such as 10,000 or more, fails.

Symptoms

After several minutes of browsing, the restore job times out, the WebUI does not respond, or the error, “The remote machine: [MACHINE_NAME] is unavailable,” appears.

Solution 1

Use Catalog Search to find the item that you want to restore.

Solution 2

Manually increase the web services physical client long timeout settings by completing the following steps:

1
In the Navigation pane, click Change Settings.
2
On the NetVault Server Settings page, under Services, click Web Service.
3
In the Web Service dialog box, configure the Physical Client Long Timeout setting to the maximum amount of 60,000 seconds.

Safe Mode in NetVault

The following error conditions can force NetVault to run in Safe Mode:

•
A key process such as Media Manager or Schedule Manager fails to start.
•
The PostgreSQL database is unavailable or NetVault is unable to connect to one or more databases.
•
The NetVault Server is low on disk space.

When these errors occur, NetVault continues to run in a restricted mode, allowing you to use the WebUI to diagnose and troubleshoot the problems.

This file keeps the cause of NetVault Server to run in Safe Mode.

In safe mode, you can access the following pages:

•
Problem Summary: This page lists the issues that caused NetVault to enter safe mode. Depending on the error type, the Fix option is provided to assist you in resolving the error.
•
View Logs: You can use this page to examine the log messages, which can contain additional information about the error condition.

You can use the following options that are available on the Safe Mode pages:

•
Use the Fix option to resolve the issue: The following table describes how you can use the Fix option to resolve the error.
 
Error type
Available options

Key process failures

When NetVault enters safe mode due to this error, no options are provided to resolve the issue.

Database connection failures

The Fix option checks the connection status, and displays the following information:

•
Status of the PostgreSQL Service (whether it is running or not)
•
Connection status for Logs, Auditor, Scheduler, and Media databases

The Fix option also provides a link to restart the PostgreSQL Service.

Low disk space issues

 

The Fix option shows the disk space usage percentage, and provides the following links to free up disk space:

•
A link to delete diagnostic trace files, if there are any. This option also disables tracing on the server.
•
A link to delete online backup indexes. You can specify the amount of disk space that you want to reclaim in the Index file cleanup dialog box.
•
Restart NetVault in normal mode: Once NetVault enters safe mode, it remains in this mode whether the error is resolved or not. To exit safe mode, restart NetVault in normal mode.
You can use the Restart in normal mode button or links on the page to restart the application.
•
Search Knowledge Base articles: You can use the Knowledge Base link to search knowledge base articles for solution.
•
Restart NetVault with diagnostic tracing enabled: You can use the link on the page to restart NetVault in normal mode with diagnostics tracing enabled.
 
* 
NOTE: Diagnostic tracing should only be enabled under the guidance of Quest Technical Support.
