Information About StorNext Upgrades

Due to the potential of the MySQL database corruption when you upgrade the release of the MySQL database, Quantum added logic to the upgrade utilities to ensure that the MySQL database is cleanly shut down on upgrade (reference StorNext Bugzilla Bug 77325).

The database is shut down using a "slow shutdown" process in a MySQL setting; the setting used for the database shut down is documented in the MySQL Reference Manual (see InnoDB shutdown mode).

There are instances where excessive slowdowns on upgrade occur due to the "slow shutdown" of the MySQL database (reference StorNext Bugzilla Bug 78960).

Quantum assessed the "slow shutdown" process is ONLY required when you upgrade from a major release of MySQL to another major release.

Note: A major release of MySQL is signified by a change to the second digit in the release number. For example, MySQL 5.6 to MySQL 5.7.

The table below provides the MySQL release included in each StorNext release.

StorNext Release

MySQL Release

5.1.1 through 6.1.1

5.6

6.2.0 through 7.0.1

5.7

Quantum recommends the following, according to the releases in the table above:

  • If you are upgrading from StorNext 6.2.0 through StorNext 7.0.1, then you are NOT required to perform the "slow shutdown" process.

  • If you are upgrading from StorNext 6.1.1 (or earlier) to StorNext 6.2.0 (and later), then you MUST perform the "slow shutdown" process to avoid potential database corruption.

The following section describes the remedy for customers doing an upgrade.

Before you initiate a StorNext upgrade, add a line of text to the /usr/adic/mysql/bin/mysql_control script on both the primary and secondary MDCs to enable a fast shutdown immediately before the command to shutdown MySQL (and avoid the slow shutdown).

For example, the highlighted text in the code snippet below illustrates the line to add in the mysql_control script:

   stop)
      stopit=0
      if mysqld_running
      then
         stopit=1
         if [ -f $ENABLE_CLEAN_SHUTDOWN ] ; then                         <- Not present in earlier releases
            log_out "Requesting clean database shutdown"                 <- Not present in earlier releases
            $MYSQL_DIR/bin/mysql -e "set global innodb_fast_shutdown=0"  <- Not present in earlier releases
         fi                                                              <- Not present in earlier releases
         log_out "Stopping mysqld"
         $MYSQL_DIR/bin/mysql -e "set global innodb_fast_shutdown=1"
         $MYSQL_DIR/bin/mysqladmin --defaults-file=$MY_CNF shutdown
         sleep 1
      fi

After you add the line of text to the mysql_control script, then you can initiate the upgrade process.

Note: Do not be concerned about backing out the script change after the upgrade is finished; the StorNext upgrade process overwrites the mysql_control script.

Quantum recommends you perform a "slow shutdown", as the upgrade is currently doing. The upgrade process might require additional time due to the clean shutdown of the database during the upgrade.

Note: It is not possible to estimate the amount of time required for the upgrade process.

To prevent manual intervention in the upgrade process, Quantum plans to add logic to the StorNext upgrade process, that verifies the MySQL version (reference StorNext Bugzilla Bug 79053).
