7.2.1 Troubleshooting: Insufficient free space in a repository

This section describes the actions to take if there is insufficient free space in a repository used by a Management Server.
Perform this procedure on a Management Server.

Point

You can use this troubleshooting method when there is insufficient free space in a repository, or if the operation status is significantly different from the status at the initial installation, in order to ensure that there is sufficient free space in the repository in the future.

Increase the amount of repository space as follows:

  1. Back up the registry of a Management Server (refer to "7.1.1.4.1 Backing up a registry")

  2. Perform stored data backup processing (refer to "7.2.1.1 Database backup")

  3. Release a repository (refer to "Cancel of repository settings" in the "ETERNUS SF Installation and Setup Guide")

  4. Re-estimate the database size (refer to "Estimation of database size" in the "ETERNUS SF Installation and Setup Guide")

  5. Re-create partitions (refer to "Setup of ETERNUS SF Manager" in the "ETERNUS SF Installation and Setup Guide")

  6. Create a repository (refer to "Setup of ETERNUS SF Manager" in the "ETERNUS SF Installation and Setup Guide")

  7. Starting of a RDB daemon (refer to "8.5.3 Starting and stopping the RDB daemon")

  8. Perform saved data restoration processing (refer to "7.2.1.2 Database restoration")

  9. Perform restoration of the registry of a Management Server (refer to "7.1.1.4.2 Restoring a registry")


7.2.1.1 Database backup

This section describes the backing up of a database. You can save data stored in a database to the specified directory. This method is mainly used for copying data for reuse for other purposes. For ordinary backup purposes, use the method described in "7.1.1.3.1 Saving a database".

Note

  • A directory in which data will be saved must be created in advance.

  • To start the database backup, perform as a root user.

  • Use the location specified at Management Server installation.

Back up a database as follows:

  1. Start database backup.
    Enter the following command to start database backup:

    # /opt/swstorage/bin/stgdbbackup
  2. Confirm to continue processing.
    Enter "y" to continue processing or "n" to stop processing.

7.2.1.2 Database restoration

This section describes the restoration of a database. You can restore data that has been saved as described in "7.2.1.1 Database backup" to a database as shown below.

Note

  • Data currently stored in a database will be lost in this processing because it will be overwritten by saved data.

  • To start the database restoration, perform as a root user.

  • Use the location specified at Management Server installation.

  • When the database restoration has completed normally, the database should then be backed up to save this copy of the data. For more information on this, refer to "7.1.1.3.1 Saving a database".

Restore a database as follows:

  1. Start database restore processing.
    Enter the following command to start database restore processing:

    # /opt/swstorage/bin/stgdbrestore
  2. Confirm to continue processing.
    Enter "y" to continue processing or "n" to stop processing.

  3. Enter the name of the data storage directory where the data has been saved.
    Using an absolute pathname, enter the name of the directory in which the data is saved.

    Note

    If any part of saved data in the directory is missing, processing is not performed because data consistency may not be maintained.
