Description

Symptom

Solution

The NetVault Backup Service fails to start on a Windows-based NetVault Backup Server.

Check the Windows Event Viewer for the following message:

PDT FATAL: lock file “postmaster.pid” already exists

NetVault Backup cannot start if the PostgreSQL database that is used to store the system data does not start.

To correct this issue, delete the “postmaster.pid” file from the location referenced in the log and restart the NetVault Backup Server.

After restarting the machine, the NetVault Backup Service sometimes fails to start on a Windows-based NetVault Backup Server.

Check the Windows Event Viewer for the following message:

FATAL: could not create any TCP/IP sockets " for a PostgreSQL source

NetVault Backup cannot start if the PostgreSQL database that is used to store the system data does not start.

To correct this issue, start the Task Manager, and click Show processes from all users. You can see multiple instances of postgres32.exe running on the system. To remove all instances of postgres32.exe, select any instance of this process, and click End Process. Start the NetVault Backup Service.

The NetVault Backup Service starts, and then stops immediately on a Linux-based machine.

No error messages are displayed.

This issue can occur if the Postgres service cannot resolve the host name localhost, and fails to start.

Check the /etc/hosts file, and if the file does not contain an entry for localhost, add the entry.

While restoring a Full Backup for a volume that maintains an existing .clusterConfig folder and for which the Overwrite Existing Files option is not selected (the default), an error occurs.

Check the NetVault Backup logs for the following message:

Error 2017/06/01 23:38:06 493 Data Plugin AUTOINT9 NDMP: ERROR 0: ERROR: /mnt/backup/v6vol2/.clusterConfig/backup/c413ec4b-13e7-4ab8-87e6-28c53b478b65@3688372308_0/.BackupIndex0/.BackupIndex0 already exists, not overwriting.

To correct this issue, do either of the following:

•

Delete the .clusterConfig folder, and then run the restore job again.

•

Select the Overwrite Existing Files option for the restore job to ensure that the folder and its files are overwritten.
