Hi folks,

the Ceph CI got a new issue as of podman 3.0:

We're running this command as root:

$ /usr/bin/podman pull docker.io/ceph/ceph:v15
Error: Cannot connect to the Podman socket, make sure there is a Podman REST API service running.: failed to mount overlay for metacopy check with "nodev,metacopy=on" options: invalid argument

This this run:

http://qa-proxy.ceph.com/teuthology/yuriw-2021-02-12_16:01:06-rados:cephadm-wip-yuri2-testing-2021-02-08-1048-octopus-distro-basic-gibba/5877761/teuthology.log

Note that runnin podman pull docker.io/ceph/ceph:v15 as root worked fine on the previous podman package

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind bug

Steps to reproduce the issue:

1. install podman

2. run podman pull docker.io/ceph/ceph:v15

Describe the results you received:

$ /usr/bin/podman pull docker.io/ceph/ceph:v15
Error: Cannot connect to the Podman socket, make sure there is a Podman REST API service running.: failed to mount overlay for metacopy check with "nodev,metacopy=on" options: invalid argument

Describe the results you expected:

Additional information you deem important (e.g. issue happens only occasionally):

Output of podman info --debug:

I wasn't able to get that information till now.

Package info (e.g. output of rpm -q podman or apt list podman):

the log shows: Setting up podman (100:3.0.0-1)

Have you tested with the latest version of Podman and have you checked the Podman Troubleshooting Guide?

No
