Change the public caslib's location

As default Public is stored in /opt/sas/viya/config/data/cas/default/public/

this mount is not very large, and I would like the physical files to be stored on our main volume /sasdata/

Is it a configuration way to do so, or do we need to create a symlink?

We are using viya 3.4

@StigMortenNegar ,

Prior to deployment, the entire CAS data dir path (not just the public path) can be customized via vars.yml:

https://go.documentation.sas.com/?docsetId=dplyml0phy0lax&docsetTarget=n1knvzbsifo9xqn1al0bh7wxrrkg.htm&docsetVersion=3.4&locale=en#n0y11x45tq21tan1ee3hpwkccpm2

However, after deployment, there is no simple method to change the paths already in use by caslibs like Public. Therefore, I recommend making /opt/sas/viya/config/data/cas/default/public a symlink to the desired new location on the CAS Controller:

- Stop CAS
- Copy the content in /opt/sas/viya/config/data/cas/default/public to a new location, preserving permissions on the files
- The new directory should be 777 cas:sas to match the old path
- Delete the now-empty dir /opt/sas/viya/config/data/cas/default/public
- Make a symlink
ln -s <new dir containing the public files> /opt/sas/viya/config/data/cas/default/public
- Start CAS

Thank you, a symlink it will be 🙂
