I am trying to install Lemur on CentOS 7.6 (7.6.1810) to integrate with Object

install. I already had Lustre client (2.12.3) installed on the machine, so I

I am looking for the various policy rules which can be applied for Lustre
Persistent Client Cache. In the docs, I see below example using projid,
fname and uid. Where can I find a complete list of supported rules.
Also is there a way for PCC to only cache content of few folders
