[問題]ubuntu上建立drbd的問題

[mmxmmxmmx (***********先生)]

我現在的問題是建立drbd到了兩台主機要sudo drbdadm create-md r0 後就卡在那邊一點
訊息也沒有,我用的是drbd8-utils

server1的hosts設定如下
127.0.0.1       localhost
127.0.1.1       server1.dom23.com       server1.dom23.com
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
10.120.223.1 server1.dom23.com     server1.dom23.com
10.120.223.2 server2.dom23.com     server2.dom23.com

server2的hosts設定如下

127.0.0.1       localhost
127.0.1.1       server2.dom23.com       server2.dom23.com
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
10.120.223.1 server1.dom23.com         server1.dom23.com
10.120.223.2 server2.dom23.com         server2.dom23.com

在server1的/etc/fstab設定如下

UUID=bf895aa3-5892-4cc7-afd2-3d696716e283 /               ext4
errors=remount-ro 0       1
# swap was on /dev/sda5 during installation
UUID=f9953345-5e7d-41a2-a958-41babe1bbe42 none            swap    sw
    0       0/dev/sdb1         /DRBD               ext3  defaults  0 0

在server2的/etc/fstab設定如下

UUID=90d60978-95c7-418a-adeb-112f1cd6df33 /               ext4
errors=remount-ro 0       1
# swap was on /dev/sda5 during installation
UUID=bc733dc4-f37d-4d0a-80aa-c704163cf5ea none            swap    sw
    0       0
/dev/sdb1  /DRBD  ext3  defaults 0 0

server1合server2 /etc/drbd.conf設定如下

global { usage-count no; }
common { syncer { rate 10M; } }
resource r0 {
        protocol C;
        startup {
                wfc-timeout  60;
                degr-wfc-timeout 60;
        }
        net {
                cram-hmac-alg sha1;
                shared-secret "secret";
        }
        on server1.dom23.com {
                device /dev/drbd0;
                disk /dev/sdb1;
                address 10.120.223.1:7788;
                meta-disk internal;
        }
        on server2.dom23.com {
                device /dev/drbd0;
                disk /dev/sdb1;
                address 10.120.223.2:7788;
                meta-disk internal;
        }
}


而server1的主機名稱是server1.dom23.com  server2的主機名稱是server2.dom23.com,
server1的eth0是10.120.223.1 eth1是10.120.230.1  ,server2的eth0是10.120.223.2
eth1是10.120.223.2
,想請問我打sudo drbdadm create-md r0 會完全連個訊息都沒有,我看網路上至少都會有
個
Writing meta data...頂多是error掉但我是什麼都沒有然後按enter選yes會出現下面的
訊息

md_offset 32211202048
al_offset 32211169280
bm_offset 32210186240

Found ext3 filesystem
    31456256 kB data area apparently used
    31455260 kB left usable by current configuration

Device size would be truncated, which
would corrupt data and result in
'access beyond end of device' errors.
You need to either
   * use external meta data (recommended)
   * shrink that filesystem first
   * zero out the device (destroy the filesystem)
Operation refused.

Command 'drbdmeta 0 v08 /dev/sdb1 internal create-md' terminated with exit
code 40

不知道有沒有大大可以幫初學linux指點明路,謝謝~
