Current cluster RAID1 test script

Current state of testing supplied by Changhui Zhong <czhong> - Associate Quality Engineer,Kernel QE

Hi,Brassow Jonathan

Yes, I am the person  of the MD test. My test is a simple automation script written for  https://bugzilla.redhat.com/show_bug.cgi?id=1654482 ,this automation is to modify the kernel configuration so that the md_cluster module can enabled in RHEL8 kernels, then create a cluster with one node and create MD_RAID1.

I used a single server to create cluster and raid1, not use multiple servers to create  cluster.If you want to achieve when involve failing systems while ensuring other systems continue to operate and coordinating drive failures,that I need a real cluster environment with multiple nodes.if I have the permissions of your test environment, I can experiment on it.

Which detailed functional test points do you want to test for cluster MD RAID1?

The test machine I am using is a single server that is immediately acquired from the beaker machine pool, which may be different from the test environment you are using.

I uploaded my script main.sh in the attachment. feel free to contact me if you have any questions.

Thanks,
Changhui

The test cases are simple.we will add more test cases in the future to cover the tests of cluster md raid1 and raid10
