Adding space to the data directory of the Linux host

Contributors netapp-shwetav

If you allotted insufficient disk space to the /opt/netapp/data directory to support Unified Manager when you originally set up the Linux host and then installed Unified Manager, you can add disk space after installation by increasing disk space on the /opt/netapp/data directory.

What you'll need

You must have root user access to the Red Hat Enterprise Linux or CentOS Linux machine on which Unified Manager is installed.

We recommend that you back up the Unified Manager database before increasing the size of the data directory.

  1. Log in as root user to the Linux machine on which you want to add disk space.

  2. Stop the Unified Manager service and the associated MySQL software in the order shown:

    systemctl stop ocieau ocie mysqld

  3. Create a temporary backup folder (for example, /backup-data) with sufficient disk space to contain the data in the current /opt/netapp/data directory.

  4. Copy the content and privilege configuration of the existing /opt/netapp/data directory to the backup data directory:

    cp -arp /opt/netapp/data/* /backup-data

  5. If SE Linux is enabled:

    1. Get the SE Linux type for folders on existing /opt/netapp/data folder:

      se_type= ls -Z /opt/netapp/data | awk '{print $4}' | awk -F: '{print $3}' | head -1

      The system returns a confirmation similar to the following:

      echo $se_type
    2. Run the chcon command to set the SE Linux type for the backup directory:

      chcon -R --type=mysqld_db_t /backup-data

  6. Remove the contents of the /opt/netapp/data directory:

    1. cd /opt/netapp/data

    2. rm -rf *

  7. Expand the size of the /opt/netapp/data directory to a minimum of 150 GB through LVM commands or by adding extra disks.


    If you have created /opt/netapp/data from a disk, then you should not try to mount /opt/netapp/data as an NFS or CIFS share. Because, in this case, if you try to expand the disk space, some LVM commands, such as resize and extend might not work as expected.

  8. Confirm that the /opt/netapp/data directory owner (mysql) and group (root) are unchanged:

    ls -ltr /opt/netapp/ | grep data

    The system returns a confirmation similar to the following:

    drwxr-xr-x.  17 mysql root  4096 Aug 28 13:08 data
  9. If SE Linux is enabled, confirm that the context for the /opt/netapp/data directory is still set to mysqld_db_t:

    1. touch /opt/netapp/data/abc

    2. ls -Z /opt/netapp/data/abc

      The system returns a confirmation similar to the following:

      -rw-r--r--. root root unconfined_u:object_r:mysqld_db_t:s0 /opt/netapp/data/abc
  10. Delete the file abc so that this extraneous file does not cause a database error in the future.

  11. Copy the contents from backup-data back to the expanded /opt/netapp/data directory:

    cp -arp /backup-data/* /opt/netapp/data/

  12. If SE Linux is enabled, run the following command:

    chcon -R --type=mysqld_db_t /opt/netapp/data

  13. Start the MySQL service:

    systemctl start mysqld

  14. After the MySQL service is started, start the ocie and ocieau services in the order shown:

    systemctl start ocie ocieau

  15. After all of the services are started, delete the backup folder /backup-data:

    rm -rf /backup-data
