### Custom Vars not updating <a id="upgrading-to-2-9-custom-vars-not-updating"></a>
A rare issue preventing the custom vars of objects created prior to 2.9.0 being updated when changed may occur. To
remedy this the config checksums of the affected type need to be reset to trigger a full update. The following is an
example of how to do this for Hosts in mysql:
remedy this, truncate the customvar tables and restart Icinga 2. The following is an example of how to do this with mysql:
```
$ mysql -uroot -picinga icinga
MariaDB [icinga]> UPDATE icinga_hosts SET config_hash = NULL;
MariaDB [icinga]> truncate icinga_customvariables;
Query OK, 0 rows affected (0.05 sec)
MariaDB [icinga]> truncate icinga_customvariablestatus;
Query OK, 0 rows affected (0.03 sec)
MariaDB [icinga]> exit
Bye
$ sudo systemctl restart icinga2
```
Custom vars should now be up to date.
Custom vars should now stay up to date.
