How reproducible:

often


Steps to Reproduce:

I noticed this issue after repetitive actions to create CEPH cluster using rook. I used https://rook.io/docs/rook/master/ceph-csi-drivers.html to create ceph-csi
However I do not think this is ceph related.

Actual results:

Pods fails to start 

Expected results:

pod to start 

Additional info:

It looks more like container runtime related problem if it can't mount stuff into the containers rootfs.

What version of cri-o is this on? Anything that is not 1.13.6 or 1.13.9 has some storage issues.

Hi ekuric, help have a check with cri-o-1.13.10-0.2.dev.rhaos4.1.git3253f9f,

I think I do not follow what issue here might be, you have troubles to setup ceph with csi following https://rook.io/docs/rook/master/ceph-csi-drivers.html ?
