How to restore a mirror chunk

  • 1.  How to restore a mirror chunk

    I want to test with chunk mirror.

    When data is written to the disk, it will be written to the chunk file and mirror chunk

    When a chunk file is damaged, the database will not stop trading and will continue trading with another chunk.

    After the damaged chunk file is repaired,

    what if it is restored to the state of chunk and mirror chunk?

    If a chunk uses a raw device and a chunk file is damaged, can I re divide a raw device through LVM to mirror the chunk, but how to synchronize the data?

    Use onspaces to bring the mirror back online and it will resync automagically
