Re: How to replace a dead brick? (3.6.5)

    Follow the steps at:

http://gluster.readthedocs.org/en/latest/Administrator%20Guide/Managing%20Volumes/#replace-brick

    
    Read the steps at section:

    "Replacing brick in Replicate/Distributed Replicate volumes".

    
    We are working on making all the extra steps vanish and just one
    command will take care of everything going forward. Will update
    gluster-users once that happens.

      So... this kinda applies to me too and I want to
        get some clarification: I have the following setup
        

          # gluster volume info
          

          Volume Name: gv0
          Type: Replicate
          Volume ID:
              fc50d049-cebe-4a3f-82a6-748847226099
          Status: Started
          Number of Bricks: 1 x 3
              = 3
          Transport-type: tcp
          Bricks:
          Brick1:
              eapps-gluster01:/export/sdb1/gv0
          Brick2:
              eapps-gluster02:/export/sdb1/gv0
          Brick3:
              eapps-gluster03:/export/sdb1/gv0
          Options Reconfigured:
          diagnostics.count-fop-hits:
              on
          diagnostics.latency-measurement:
              on
          nfs.drc: off
        
        
        eapps-gluster03 had a hard drive failure so I replaced it,
          formatted the drive and now need gluster to be happy again.
          Gluster put a .glusterfs folder in /export/sdb1/gv0 but
          nothing else has shown up and the brick is offline. I read the
          docs on replacing a brick but seem to be missing something and
          would appreciate some help. Thanks!

               On 3.7.4, all you
                need to do is execute "gluster volume replace-brick
                <volname> commit force" and rest will be taken
                care by afr. We are in the process of coming up with new
                commands like "gluster volume reset-brick
                <volname> start/commit" for wiping/re-formatting
                of the disk. So wait just a little longer :-).

                              I
                                documented this on my blog at https://joejulian.name/blog/replacing-a-brick-on-glusterfs-340/
                                which is still accurate for the latest
                                version.

                                
                                The bug report I filed for this was
                                closed without resolution. I assume
                                there's no plans for ever making this
                                easy for administrators.

                                https://bugzilla.redhat.com/show_bug.cgi?id=991084

                              
                        Yes, its the sort of
                          workaround one can never remember in an
                          emergency, you'd have to google it up ...

                          
                        In the case I was
                          working with, probably easier and quicker to
                          do a remove-brick/add-brick.

                          
                        thanks,
