The database contains:

•MAC-Specific Provisioning Roles

•MAC-Specific Provisioning Role Templates

•MAC-Independent Provisioning Roles

•MAC-Specific Imaging Roles

 

The database does not contain files necessary to provision or image individual systems. See After Restoring the Database.

 

A database backup is made automatically on a daily basis and the the backups are located in:

/usr/local/linmin/pgDBbkup/

 

The daily backup is then compared to the prior backup, and if no changes to the database have been made, the newer backup will be overwritten during a subsequent backup when the database contents change.

 

 

Backup the Database

 

# cd /usr/local/linmin/

# ./lbmpPostgresBackup.sh

...checking for difference since last backup

...diff returned:1

Changes have been made since last backup check, backup taken:

... pg_dump_bkp.20100915-122433

Restore the Database

 

Before restoring a database:

•End all GUI sessions

•Ensure that no provisioning or imaging events are underway

 

# cd /usr/local/linmin/pgDBbkup/

# ./linmin-bmp-PostgresRestore.sh

Postgres Restore

 

Selecting the 'restore' option will stop LinMin services,

... services will be restarted after the DB restore is completed.

Key 'restore' then Enter to continue or Enter to exit: restore

After Restoring the Database

 

After the successful restore of the database, you must use the GUI or API to:

•Toggle the MAC-Specific Provisioning Roles (for example, from Ignore to Next Boot)

•Toggle the MAC-Specific Imaging Roles (for example, from Reset to Backup)

 

This is required to generate the files required to enable provisioning and imaging functions on specific systems.
