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.
