Subject: crashblk: a block device crash emulator.
Date: Thu, 14 Jan 2016 10:50:37 +0900 [thread overview]
Message-ID: <5696FEED.1080604@labs.cybozu.co.jp> (raw)
Hi all,
I'm developing 'crashblk'.
It is a memory block device driver to emulate crash, IO error,
and various response time.
The source code repository is here:
https://github.com/starpos/crashblk/
It is very useful to test wrapper block device drivers,
and must be useful to test filesystems also.
I used it to test WalB (https://walb-linux.github.io/),
which is a wrapper block device driver for backup and asynchronous
replication, and found/confirmed several bugs.
If you are interested in crashblk, try it and give me feedback!
Thank you.
Takashi
