Hi all.

I am trying to do some tests on DRBD running on linux on Sun Netra 240

I am using drbd-8.0.5.

My problem is that I do not manage to do the first synchronisation.

When every thing is configured and started, I am in state
secondary/secondary and inconsistent/inconsistent. This is normal!


#> drbdadm -- --overwrite-data-of-peer primary all just do nothing.

The state of my ressource does not change.

#> drbdsetup /dev/drbd4 primary --overwrite-data-of-peer just says "bus


I do not know if it is the same problem, bu an error occurs at the metadata

#> drbdadm create-md all

Valid meta-data already in place, recreate new?

[need to type 'yes' to confirm] yes

Creating meta data...

initialising activity log

NOT initialized bitmap (284 KB)

msync(on_disk_md): Invalid argument

operation failed

Here is the dump-md output:

#> drbdadm dump-md r4

version "v08";

uuid {

    0x0000000000000004; 0x0000000000000000; 0x0000000000000000;

    flags 0x00000000;


la-size-sect 0;

bm-byte-per-bit 4096;

device-uuid 0x0000000000000000;

# bm-bytes 0;

# bits-set 0;

bm {


I have also some error when detaching drbd from the ressource:

#> drbdadm down all

[881921.569358] drbd4: short read expecting header on sock: r=-512

[881921.647238] drbd4: meta connection shut down by peer.

Thanks by advance for any help  ;-)
