Stopping and Disabling Orchestrator Services on Each Orchestrator Server

You need to prepare each system to share the updated MySQL database and to run the ACM software, which will be responsible for starting and stopping the Orchestrator services. Therefore, you need to disable services that utilize the MySQL database (the mysqld process is started by aspera-orchestrator) and prevent those services from being started during the system boot-up process on each server.

To stop all Orchestrator services and MySQL on both nodes, run the following commands on each server:
```
$ asctl orchestrator:stop
$ asctl mysql:stop
```
CAUTION:
Confirm that the AsperaOrchestrator services are stopped before proceeding to the next step. Continuing while the services are running may corrupt the MySQL database.
Run the following command:
```
# service AsperaOrchestrator status
Checking status of AsperaOrchestrator …
Status is stopped
```
Confirm that the following folder has rwxr-xr-x permissions:
```
/mnt/shared/orchestrator/
```
This folder is the Orchestrator mount point on the shared storage. If it does not have the necessary permissions, change them with the following command:
```
$ chmod 755 /mnt/shared/orchestrator/
```
Create a mysql_data directory under the mount point for the MySQL shared data files.
Open the /etc/group and /etc/passwd files to confirm that mysql group-id and mysql user-id are the same on both nodes.

On both nodes, run the following:

$ cd /opt/aspera/common/mysql
$ mv ./data ./data.bak
$ ln -s /mnt/shared/orchestrator/mysql_data ./data
$ chown -h mysql.mysql ./data

Check the results of the operation Step 5 by running a list operation on the mysql directory.

$ ls -lah /opt/aspera/common/mysql
...
lrwxrwxrwx 1 mysql mysql 4 Jun 12 15:25 data -> /mnt/shared/orchestrator/mysql_data
drwxr-x--- 5 mysql mysql 4.0K Jan 18 16:26 data.bak
...

Create an empty file in the following folder:
```
/opt/aspera/common/mysql/data/
```

Run the following commands to confirm that the folder in Step 7 comes with mysql ownership (rather than nobody ownership):

$ cd /opt/aspera/common/mysql/data/
$ sudo -u mysql touch toto.txt
$ ls –l
-rw-r--r-- 1 mysql mysql        0 May 12 08:19 toto.txt
$ rm –f toto.txt

On one node where the shared storage is accessible, copy the MySQL data into the shared volume.
```
$ cp -R /opt/aspera/common/mysql/data.bak/* 
/opt/aspera/common/mysql/data
```
Ensure that the files under the following folder are owned by the mysql user and group.

On the other node, verify that you can see the data files in this directory.

It may be necessary to perform a failover to make the shared storage visible. See Manual Failover (Disabling ACM).
