[DRBD-user] DRBD and ISCSI problem

[Marcio Demetrio Bacci]

Hi,

I have a problem between DRBD and iscsi disk mapping.

The problem is the following:

When I restart my Debian 9 server my DRBD service don't start, I believe
because the iscsi doesn't ready.

This is my log messages in /var//log/syslog:

Feb 21 12:03:25 bkp kernel: [   10.459216] scsi host11: iSCSI Initiator

disk

Bellow, is my resourse file in /etc/drbd.d/hd-bacula.res

resource hd-bacula {

   on bkp {
        device    /dev/drbd0;
        disk      /dev/lun-hd-bacula;
        address   192.168.10.47:7790;
        meta-disk internal;
    }

    on bkp2 {
        device    /dev/drbd0;
        disk      /dev/lun-hd-bacula-2;
        address   192.168.10.1:7790;
        meta-disk internal;
    }
}

And /etc/drbd.d/global_common.conf

global {
    usage-count yes;
    # minor-count dialog-refresh disable-ip-verification
}

common {
    protocol C;
    handlers {
    # These are EXAMPLE handlers only.
    # They may have severe implications,

    }

    startup {

    }

    options {

    shared-secret "dont forget me again";
    }
    syncer {
    # rate after al-extents use-rle cpu-mask verify-alg csums-alg
    rate 1000M;
    }

}

Can anybody help me ?
