I use wmware workstation to run two virtual machines with
OpenVZ 2.6.32-042stab108.2 installed on top on CentOS 6.6. I have created another primary partition, /dev/sda4, to configure it as drbd resource. I also created a filsystem on it. The second machine is actually created using the virtual disk of the first one, with changed hostname and eth0 ip address. The drbd configuration file is this:
global { usage-count no; }
common { syncer { rate 100M; } }
resource r0 {
protocol C;
startup {
wfc-timeout 15;
degr-wfc-timeout 60;
}
net {
cram-hmac-alg sha1;
shared-secret "password";
}
on primary {
device /dev/drbd0;
disk /dev/sda4;
address 192.168.18.10:7788;
meta-disk internal;
}
on secondary {
device /dev/drbd0;
disk /dev/sda4;
address 192.168.18.20:7788;
meta-disk internal;
}
}
After creating the resource with **drbdadm create-md r0**, when I enter **service drbd start**, I get:
Failure: (127) Device minor not allocated.
The output of **drbdadm dump all** might be helpful:
[root@primary ~]# drbdadm dump all
# /etc/drbd.conf
# resource r0 on primary: not ignored, not stacked
resource r0 {
protocol C;
on primary {
device /dev/drbd0 minor 0;
disk /dev/sda4;
address ipv4 192.168.18.10:7788;
meta-disk internal;
}
on secondary {
device /dev/drbd0 minor 0;
disk /dev/sda4;
address ipv4 192.168.18.20:7788;
meta-disk internal;
}
net {
cram-hmac-alg sha1;
shared-secret danuts;
}
startup {
wfc-timeout 15;
degr-wfc-timeout 60;
}
}
What is causing this error and how can it be mitigated? Thanks!
