Comment 7 for bug 2031106

I think it would be preferable to use become:true to ensure container images are stored in /var/lib instead of /home/tripleo-admin. The size of the /home volume is chosen on the assumption that there are no substantial storage requirements for a typical install, and manila-cephfsganesha-config seems to be unique in requiring that storage.

If this fix is not possible, another workaround would be to set custom growvols args for this role to grow /home to the required size, see:
