I have install drbd 0.7.14 on 2 centos 4.2 boxes. Everything is running fine
on one box(hostname cluster2)
but on the machine with the hostname cluster1 I get the following message
when starting the service:
service drbd start
Starting DRBD resources: [ d0 ioctl(,SET_DISK_CONFIG,) failed: Invalid
argument
Lower device is already mounted.
cmd /sbin/drbdsetup /dev/drbd1 disk /dev/hdc1 internal -1 failed!
Both systems appear to be the same but I can not see why cluster1 does not
work. The mount command does not show it mounted:
(cluster1) mount
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
none on /proc type proc (rw)
none on /sys type sysfs (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
usbfs on /proc/bus/usb type usbfs (rw)

none on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
(cluster2)
mount

none on /proc type proc (rw)

none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
The drbd.conf file on both systems:
resource drbd0 {
protocol C;
incon-degr-cmd "halt -f";
on cluster1 {
device /dev/drbd1;
disk /dev/hdc1;
address 10.0.0.2:7789;
meta-disk internal;
}
on cluster2 {
device /dev/drbd1;
disk /dev/hdc1;
address 10.0.03:7789;
meta-disk internal;
}
}
