Subject: [PATCH for-next 0/5] Enable Fault Injection for RNBD
Date: Tue, 6 Apr 2021 09:37:22 +0200 [thread overview]
Message-ID: <20210406073727.172380-1-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 RNBD module. RNBD 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, RNBD is able to export interfaces
to fail RNBD client and server.
Following fault injection points are enabled:
- fail BIO processing on RNBD server side
- fail IO transferation on RNBD client side
- fail device unmapping on RNBD client side
This patch set is just a starting point. We will enable various
faults and test as many error cases as possible.
Best regards
