[DRBD-user] Long drbdadm verify

[Christian Fertsch]

Dear Mailing-list member,

I have a 2 Node DRBD-Setup with 4 DRBD-Device. The Size of the drbd is ~ 400GB. After some Network Problems we started a "drbdadm verify mysql". After 1.5 hours 85% were done. After that it got slower and slower. Now after 4 - 5 weeks the verify is 93%. What can we do to get a clean satisfaction. Here ist th current configuration of the DRBD-Resource:



resource mysql {

   disk {
        resync-rate 1000M;
  }


  net {
        protocol C;
        verify-alg md5;
        allow-two-primaries no;
        after-sb-0pri discard-zero-changes;
        after-sb-1pri discard-secondary;
        after-sb-2pri disconnect;
  }

  options {
        auto-promote no;
        on-no-data-accessible io-error;
  }
 
  on node1 {
        device /dev/drbd1 minor 1;
        disk /dev/datavg/lv_mysql;
        address ipv4 172.23.80.2:7789;
        meta-disk /dev/datavg/lv_metadata[1];
        node-id 1;
  }

  on node2 {
        device /dev/drbd1 minor 1;
        disk /dev/datavg/lv_mysql;
        address ipv4 172.23.80.1:7789;
        meta-disk /dev/datavg/lv_metadata[1];
        node-id 2;
  }

}


Thank you in advance

Christian
