Mainframe Operational Intelligence

In order to execute the increase of the area storage for MOI LVMs is it necessary to stop the Docker processes?

OS : Linux x86_64

Release : 2.0

Component : MF OPERATIONAL INTELLIGENCE

In order for the new storage to be used the MOI microservices should be shut down and restarted.

Here are the instructions for accomplishing that requirement:

docker ps –a

Capture the LVM space allocations to compare to after the additional drives are added:

df -h

Normally you should shut down the microservices prior to adding the drive space using the commands below:

cd /opt/moi

docker ps -a

bin/plex shutdown --bg=wait

(This command will take a few minutes to complete)

Check to make sure all containers are not started and cleanup if it is necessary:

docker ps -a

(This command should return no docker containers list)

If any docker containers are still listed then run the following command to clean them up:

docker rm -f $( docker ps -a -q)

Now you would add the additional drives to increase the LVM storage allocations via the ISPF panels.

Restart appliance:

cd /opt/moi

bin/plex startup --bg=wait

Check containers for healthy status and no exits by repeating the command below every 5 minutes or so.
This process should complete within one hour.

docker ps -a
