Hi,
I'm having trouble getting DRBD to run on top of a software raid 0 or jbod device. Actually the problem is that DRBD can't seem to get the exact size of the partition. I am doing raid 0 over 2 80GB sata disk.
# fdisk -s /dev/md0
155589376
but with drbd
# drbdadm up all
drbd0: resync bitmap: bits=19448672 words=607772
drbd0: size = 74 GB (77794688 KB)
drbd0: 74 GB marked out-of-sync by on disk bit-map
drbd0: Found 4 transactions (192 active extents) in activity log
drbd0: drbdsetup [2248]: cstate Unconfigured --> StandAlone
drbd0: drbdsetup [2250]: cstate StandAlone --> Unconnected
drbd0: drbd0_receiver [2251]: cstate Unconnected --> WFConnection
# fdisk -s /dev/drbd0
77794688
And because of this I kept getting "access beyond the end of device" error. Should I manual set the disk size for drbd for raid 0 and jbod? How do I do that?
But if I used raid 1, everything seems ok.
I'm using drbd-0.7.5 and kernel 2.6.8.1
my drbd.conf
resource "drbd0" {
protocol C;
incon-degr-cmd "echo '!DRBD! pri on incon-degr' | wall ; sleep 60 ; halt -f";
disk {
on-io-error detach;
}
syncer {
rate 20M;
}
on node1 {
device /dev/drbd0;
disk /dev/md0;
address 192.168.2.1:7788;
meta-disk /dev/md3[0];
}
on node2 {
device /dev/drbd0;
disk /dev/md0;
address 192.168.2.2:7788;
meta-disk /dev/md3[0];
}
}
Best Regards,
Paul Chen
