CernVM-FS Clients

Mount CernVM-FS repositories.

Attributes

Deploy the public keys to CVMFS servers with attributes in node.cvmfs.keys.

The default configuration (affecting all mounted repositories) is defined with attributes in node.cvmfs.default_local, and written to /etc/cvmfs/default.local.

• cache_base (default /var/cache/cvmfs) – Path to the local repository cache.
• quota_limit (default 20000) – Maximum local storage consumes by a repository (in MB).
• max_ttl (default 30) – Metadata synchronisation interval (in minutes).

Defining a repository in node.cvmfs.client.config_d will render a configuration file in /etc/cvmfs/config.d/*.local. (Fore a complete list of available configuration keys refer to the CernVM-FS Technical Report.)

Example

Define defaults:

"cvmfs" => {
  "client" => {
    "default_local" => {
      "cache_base" => "/opt/cvmfs/cache",
      "quota_limit" => -1,
      "max_ttl" => 60
    },
    […]

Mount several CVMFS repositories:

"cvmfs" => {
  "client" => {
    "config_d" => {
      "alpha.devops.test" => {
        "server_url" => "http://lxcvmfs01.devops.test/cvmfs/alpha.devops.test",
        "http_proxy" => "DIRECT",
        "public_key" => "/etc/cvmfs/keys/alpha.devops.test.pub"
      },
      "betta.devops.test" => {
        "server_url" => "http://lxcvmfs02.devops.test/cvmfs/betta.devops.test",
        "public_key" => "/etc/cvmfs/keys/betta.devops.test.pub",
        "quota_limit" => 20000
      }      
    }
  },
  "keys" => {
    "alpha.devops.test.pub" => "…"
  }
}
