[Compass-ci] Re: [PATCH compass-ci] doc: optimize os_mount.md

• copy_nfsroot_to_src_lv()
• {
• src_lv=$1
• lvdisplay ${src_lv} > /dev/null || {

lvdisplay $src_lv && return

后面就不用缩进了

# create logical volume

• lvcreate -L 10G -n $(basename ${src_lv}) os || exit 1
  

exit 1 => exit

Thanks, Fengguang
