Subject: ceph-validate: use root device from ansible_mounts
X-Git-Tag: v6.0.12~23
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=f8ecb08ec263cb6fc1cef06eec31fbf942b0ef2c;p=ceph-ansible.git

ceph-validate: use root device from ansible_mounts

Instead of using findmnt command to find the device associated to the
root mount point then we can use the ansible_mounts fact.
