 Description   

Peer health detection and asymmetric router failure detection avoidance options are not documented in the Lustre Ops Manual.

Bugzilla 24404 (https://bugzilla.lustre.org/show_bug.cgi?id=24404) provides some guidance for these options and also calls out some other undocumented LNET/LND option that need improvement.

The module info shows: "Avoid asymmetrical failures: reserved, use at your own risk". I'm not sure if that needs to be the case, but I believe that avoid_asym_router_failure should be documented nonetheless.

This ticket covers several topics -

  • LNET peer health (peer_timeout, avoid_asym_router_failure - a draft of this content has been created and is being reviewed by Amir.
  • LNET message credits - this will be covered in LUDOC-189 - Document LNET Message Credits
