I want to test LWT in Scylla DB by jespen

I run this Jepsen test on the virtual machine, and my configuration is Ubuntu 20 04，docker version is 20.10.12 and docker-compose version is 1.25.0.I tried two different docker containers. 1、tjake/jepsen When I use it, report error：STDERR：E：Command line option --allow-downgrades is not understood. 01

2、jepsen-io/jepsen/docker When i use it , report error：ERROR：Command exited with non-zero status 1 on node n1：sudo -S -u root bash -c "cd/；server scylla-server start“。STDERR：Job for scylla-server.service failed because the control process exited with error code 02 This looks like DB nodes start fail. Then I try add up aio-max-nr. like this echo 16777216 >/proc/sys/fs/aio-max-nr Successfully started DB nodes But later

01 02

I tried sudo apt-get，but it don't work.

How can I handle these errors so that I can run tests？

Up aio-max-nr, either on individual DB nodes, or, for containers, on the container host.
