Subject: [PATCH 0/4] Enable Fault Injection for RTRS
Date: Tue, 6 Apr 2021 13:50:45 +0200 [thread overview]
Message-ID: <20210406115049.196527-1-gi-oh.kim@ionos.com> (raw)
My colleagues and I would like to apply the fault injection
of the Linux to test error handling of RTRS module. RTRS module
consists of client and server modules that are connected via
Infiniband network. So it is important for the client to receive
the error of the server and handle it smoothly.
When debugfs is enabled, RTRS is able to export interfaces
to fail RTRS client and server.
Following fault injection points are enabled:
- fail a request processing on RTRS client side
- fail a heart-beat transferation on RTRS server side
This patch set is just a starting point. We will enable various
faults and test as many error cases as possible.
Best regards
