two questions here

  1. the volume size don't resize successful with task overwrite size and luks
  2. the luks vol convert luks size and luks version failed

just confirm, did the role support to vol resize and convert ?
if no supported, it should feedback some failure info ?

looks change mount_point successful, so did the role just support change mount_point ?

  1. hit the error
