    Description

      Eviction is a standard mechanism for Lustre targets to protect themselves against dead or misbehaving clients.

      On a live filesystem, evictions happen, eventually and it could be useful for sysadmin to have an exact counter to monitor them and take action if needed.

      I will propose a patch where an eviction counter is added to obd_device, increased when an eviction occurs and exposed through lctl get_param.

            I see a discussion of YAML output for various parameters. I'm working on a YAML netlink version for the debugfs issue. It should provide the ability to express any stats in YAMl format when requested.
