Is this expected or is something bad happening?

[root]# drbdmeta /dev/drbd0 v08 /dev/sda3 0 wipe-md
Wiping meta data...
ioctl(,BLKFLSBUF,) failed: Bad address
operation failed

But when I repeat the same command:

[root]# drbdmeta /dev/drbd0 v08 /dev/sda3 0 wipe-md
v08 Magic number not found
There apears to be no drbd meta data to wipe out?

The same thing happens for the create-md:

[root]# drbdadm create-md drbd0
v08 Magic number not found
v07 Magic number not found
About to create a new drbd meta data block
on /dev/sda3.

 ==> This might destroy existing data! <==

Do you want to proceed?
[need to type 'yes' to confirm] yes

Creating meta data...
initialising activity log
NOT initialized bitmap (131036 KB)
ioctl(,BLKFLSBUF,) failed: Bad address
operation failed

Then I just repeat the command:

[root]# drbdadm create-md drbd0

Valid meta-data already in place, recreate new?
[need to type 'yes' to confirm]

Operation cancelled.
