* Topics for rook issue
      * rook provision step
            * Replace “sgdisk -Z /dev/sdx” with “system host-disk-wipe <node> sdx
            * “system host-disk-wipe” should check this command detail, seem this command will add GPT header to disk
            *  Add parameter to command “system host-disk-wipe” for zap disk function without GPT header
      * Corner case for wipe disk in host-reinstall
            * Confirm rook osd disk will be wiped correctly, no concern to https://review.opendev.org/#/c/737228/
      * Restore process for rook, by rebuild mon data from osd
            * Mon data could be rebuild by osd disk
            * Mon and osd pod launch by k8s, and cluster info saved in configmap, saved in etcd, which backup
            * Issue keeps open 
      * Patch request review for rook. No concern to rook deployment’s patch
