ScaleIO 2.0.1.4 + Centos7.4 SDC
Hi everyone,
I've recently added my first CentOS 7.4 SDC to one of my ScaleIO clusters. However, as soon as I map a volume to the SDC, it freezes, goes 100% CPU and just plain dies.
Have anyone seen this issue before?
I have tested this on both SDC/SDS version 2.0.1.3 and 2.0.1.4.

To any who may still be following this post.
The issue appeared after Red Hat changed the spinlock interface between the base 7.3 and 7.4 kernels. This affected kernel drivers running in VMs which relied more heavily on the spinlock mechanism, the ScaleIO SDC being one of those drivers.
Red Hat has recently released an updated kernel, found here:

Updating to the 3.10.0-693.21.1 kernel for RHEL 7.4 will resolve this issue with the RHEL VMs hanging upon map of a ScaleIO volume.
Thanks

Also, here is the statement concerning the fixed kernel release from CentOS:

Hi Cornelis,
I tried that in the lab and my CentOS 7.4 VM doesn't crash anymore, so it looks like the issue is indeed fixed with this kernel.
Cheers,
