5.4.3.3. Repairing a Mirrored Logical Device

You can use the lvconvert --repair command to repair a mirror after a disk failure. This brings the mirror back into a consistent state. The lvconvert --repair command is an interactive command that prompts you to indicate whether you want the system to attempt to replace any failed devices.
  • To skip the prompts and replace all of the failed devices, specify the -y option on the command line.
  • To skip the prompts and replace none of the failed devices, specify the -f option on the command line.
  • To skip the prompts and still indicate different replacement policies for the mirror image and the mirror log, you can specify the --use-policies argument to use the device replacement policies specified by the mirror_log_fault_policy and mirror_device_fault_policy parameters in the lvm.conf file.
