[Lustre-devel] Meaning of LND/neterrors ?

I've noticed that Lustre network error, especially LND errors, are considered as maskable errors.
That means that on a production node, where debug mask is 0, those specific errors won't be displayed if they happened.

Does that mean that they are harmless?
Do upper-layers resend their RPC/packet if LNDs report an error?

When, in my case, o2iblnd says something like "RDMA failed" (neterror). It is a big issue? Some RPC were lost or not?

Thanks in advance
