Issue

When reverting from ActiveIQ Unified Manager to earlier versions of Unified Manager, MySQL fails to start. This MySQL start failure will also cause the new install of the previous versions of UM to fail.

  • The error from running systemctl status mysqld is:

mysqld.service - MySQL Server
Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)
Active: failed (Result: start-limit) since Tue 2020-05-05 16:38:36 -07; 7min ago

  • When checking /var/log/mysqld.log the following is seen:

2020-05-05T00:21:13.687193Z 0 [ERROR] [FATAL] InnoDB: Table flags are 0 in the data dictionary but the flags in file ./ibdata1 are 0x4000!

  • The error seen on the CLI during the UM install is:

Job for mysqld.service failed because the control process exited with error code. See "systemctl status mysqld.service" and "journalctl -xe" for details.

ERROR: MySQL pid missing after 600s, unable to continue.
