Lustre RPCs
-----------
[[lustre-rpcs]]

Lustre operations are denoted by the 'pb_opc' op-code field of the
RPC descriptor. Each operation is implemented as a pair of messages,
with the 'pb_type' field set to PTLRPC_MSG_REQUEST for requests
initiating the operation, and PTLRPC_MSG_REPLY for replies. Note that
as a general matter, the receipt by a client of the reply message only
assures the client hat the server has initiated the action, if
any. See the discussion on <<transno,transaction numbers>>
and <<recovery>> for how the client is given confirmation that a
request has been completed.
