Cause

This issue can appear when installing the NMC server software on a system with no existing NMC database ( /nsr/nmc/nmcdb ). The postgres user created during the nmc_config script fails to initialize the NMC database because of incorrect permissions set on the OS /tmp directory. This directory should have full read, write, execute permissions for all users. The postgres user creates a .lock file under /tmp, if it fails to do this, the nmcdb will fail to initialize.

Resolution

1. Log into the NetWorker server as root2,a. Confirm that /tmp has full read, write, execute access for all users: ls -la / | grep /tmp Example: # ls -la / | grep tmpdrwxrwxrwt. 51 root root 8192 Nov 14 09:41 tmp NOTE: the above highlighted value indicates full read, write, execute permissions for all users. If you have any other permissions settings this will need to be changed. 2,b. If the permissions are incorrect, correct them by running: chmod 777 /tmp Example: [root@nmcserver linux_x86_64]# ls -la / | grep tmp drwx------. 51 root root 8192 Nov 16 09:18 tmp [root@nmcserver linux_x86_64]# chmod 777 /tmp [root@nmcserver linux_x86_64]# ls -la / | grep tmp drwxrwxrwx. 51 root root 8192 Nov 16 09:18 tmp 3. Rename the existing /nsr/nmc/nmcdb: mv /nsr/nmc/nmcdb /nsr/nmc/nmcdb.bak NOTE: If the nmcdb is renamed you will not be able to pull NMC reports from prior to renaming. NMC Role configurations for external authentication will also have been removed. To recover the nmcdb see NetWorker: How to Recover the NMC database?. This can be done once the process in this KB has been completed. 4. rerun nmc_config: [root@nmcserver linux_x86_64]# /opt/lgtonmc/bin/nmc_config NOTE ==== Install has detected the configuration file of a previous lgtonmc package. Install will attempt to read the configuration parameters in this file and present them as default values where appropriate. Please modify any value that is incorrect or needs to be changed.

If you specify a user that does not exist, the configuration process will provide you with the option to create the user account. Specify the user for the database server [postgres]: Specify the directory to use for the LGTOnmc database [/nsr/nmc/nmcdb]: Do you want to migrate the NMC server data from a previous LGTOnmc 8.x.x release [n]?

Confirm that the GST service has started: systemctl status gst 6. If the NMC service is not running start it with: systemctl start gst 6.
