4.4.3.3. 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.
