Hi DRBD guru, perhaps a stupid question, but I hope that u can help me.
This is my /etc/drbd.conf
vm:~# more /etc/drbd.conf
resource drbd0 {
protocol C;
startup {
wfc-timeout 1; # 2 minutes.
}
net {
}
syncer {
rate 100M;
}
on HOST_2 {
device /dev/drbd0;
disk /dev/???;
address 192.168.1.200:7788;
meta-disk internal;
}
on HOST_2 {
device /dev/drbd0;
disk /dev/???;
address 192.168.1.100:7788;
meta-disk internal;
}
}
The problem is that on my 2 machine I have a RAID 1 with :
~# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/md0 111G 12G 94G 11% /
tmpfs 1014M 0 1014M 0% /dev/shm
so, I don't know what I must put as "disk" ; if I set /dev/md0
~# /etc/init.d/drbd start
Starting DRBD resources: [ d0 Lower device (/dev/md0) is already mounted
cmd /sbin/drbdsetup /dev/drbd0 disk /dev/md0 internal -1 failed!
if I create a new device with
mknod -m 777 /dev/prova b 147 0
and set /dev/prova like disk in /etc/drbd.conf I receive
:~# /etc/init.d/drbd start
Starting DRBD resources: [ d0 Can not open lower device '/dev/prova':
Read-only file system
cmd /sbin/drbdsetup /dev/drbd0 disk /dev/prova internal -1 failed!
Any suggest, comment, (flout) ?
Thanks in advance and best regards.
