Reinstalling a Compute Node

To reinstall a compute node:

1. Stop the wakari-compute process on the node:

sudo service wakari-compute stop

2. Copy your .condarc file to the /opt/wakari directory on your Compute node:

cp /opt/wakari/anaconda/.condarc /opt/wakari

3. Move your /opt/wakari/wakari-compute directory to a secondary location:

mv /opt/wakari/wakari-compute /opt/wakari/wakari-compute-backup

In this example it has moved to /opt/wakari/anaconda-backup.

4. After backing up these directories, run the Compute bash installer again.

NOTE: The documentation links to the most recent version of AEN. If you are using a different version, follow the instructions for your actual version.

5. Copy the config file wk-compute-launcher-config.json to the new wakari-compute directory from your backup directories:

cp /opt/wakari/wakari-compute-backup/etc/wakari/wk-compute-launcher-config.json /opt/wakari/wakari-compute/etc/wakari

6. Copy your .condarc to the newly created /opt/wakari/anaconda directory from your /opt/wakari directory:

cp /opt/wakari/.condarc /opt/wakari/anaconda/

7. Start the wakari-compute service again:

sudo service wakari-compute start
