Hello People,
About my problems with drdb, I'll tell how is my network.
I want use DRBD from replication the one (or more) partitions from second machine.
I create one network with 3 machines, two servers (clusters) and one client (notebook).
Then firewall is not a trouble.
Each machine have two network card.
ubuntu-cluster1
eth0 : 192.168.1.1
eth1 : 10.0.0.1
ubuntu-cluster2
eth0 : 192.168.1.2
eth1 : 10.0.0.2
My drbd.conf is :
global {
usage-count yes;
}
common {
protocol C;
}
resource r0 {
on ubuntu-cluster1 {
device /dev/drbd0;
disk /dev/sda7;
address 10.0.0.1:7789;
meta-disk internal;
}
on ubuntu-cluster2 {
device /dev/drbd0;
disk /dev/sda7;
address 10.0.0.2:7789;
meta-disk internal;
}
}
My partitions in two hard disk :
root at ubuntu-cluster1:~# fdisk -l
Disk /dev/sda: 250.0 GB, 250000000000 bytes
255 heads, 63 sectors/track, 30394 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 6 48163+ 83 Linux
/dev/sda2 7 30394 244091610 5 Extended
/dev/sda5 7 492 3903763+ 82 Linux swap / Solaris
/dev/sda6 493 5355 39062016 83 Linux
/dev/sda7 5356 5379 192748+ 83 Linux
/dev/sda8 5380 30394 200932956 83 Linux
root at ubuntu-cluster2:~# fdisk -l
Disk /dev/sda: 250.0 GB, 250000000000 bytes
255 heads, 63 sectors/track, 30394 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sda1 1 6 48163+ 83 Linux

/dev/sda5 7 492 3903763+ 82 Linux swap / Solaris
/dev/sda6 493 5355 39062016 83 Linux
/dev/sda7 5356 5379 192748+ 83 Linux
/dev/sda8 5380 30394 200932956 83 Linux
I think that partition is not problem.
I've been installed drbd 8.2.6, but
the old resource is there.
See my commands :
root at ubuntu-cluster2:~# drbdadm create-md r0
Device '/dev/drbd0' is configured!
Command 'drbdmeta /dev/drbd0 v08 /dev/sda7 internal create-md' terminated with exit code 20
drbdadm aborting
root at ubuntu-cluster2:~# drbdadm attach r0
/dev/drbd0: Failure: (124) Device is attached to a disk (use detach first)
Command 'drbdsetup /dev/drbd0 disk /dev/sda7 /dev/sda7 internal --set-defaults --create-device' terminated with exit code 10
root at ubuntu-cluster2:~# drbdadm connect r0
/dev/drbd0: Failure: (125) Device has a net-config (use disconnect first)
Command 'drbdsetup /dev/drbd0 net 10.0.0.2:7789 10.0.0.1:7789 C --set-defaults --create-device' terminated with exit code 1
Do I recreate the resource ?
How Do I make this ?
When i started the script /etc/init.d/drbd, still come this message :
root at ubuntu-cluster1:~# /etc/init.d/drbd start
Starting DRBD resources: [ ].
..........
***************************************************************
DRBD's startup script waits for the peer node(s) to appear.
- In case this node was already a degraded cluster before the
reboot the timeout is 0 seconds. [degr-wfc-timeout]
- If the peer was available before the reboot the timeout will
expire after 0 seconds. [wfc-timeout]
(These values are for resource 'r0'; 0 sec -> wait forever)
To abort waiting enter 'yes' [ 76 ]
This task is very hard :)
Best regards,
Faria
