[DRBD-user] drbd-8.0_pre6 is not recognizing its metadata

[Maurice Volaski]

I am experimenting with drbd-8.0_pre6 under gentoo-2.6.18-r1 on an 
amd64 system.

When I start drbd, it claims:
Failure: (119) No valid meta-data signature found.

and the log says:

Dec  1 19:01:07 [kernel] [  192.645319] drbd0: disk( Diskless -> Attaching )
Dec  1 19:01:07 [kernel] [  192.645418] drbd0: unexpected md_size: 
262144 (expected 975872)
Dec  1 19:01:07 [kernel] [  192.645422] drbd0: bitmap not locked in bm_unlock
Dec  1 19:01:07 [kernel] [  192.645425] drbd0: disk( Attaching -> Diskless )
Dec  1 19:01:07 [kernel] [  192.645751] drbd0: drbd_bm_resize called 
with capacity == 0

--
So I execute drbdadm create-md all and it says :
Valid meta-data already in place, recreate new?
[need to type 'yes' to confirm] yes

Creating meta data...
initialising activity log
initialising bitmap (131036 KB)
100%
New drbd meta data block successfully created.
Ignoring additional arguments

This repeats for twice for the remaining two meta-data portions.

--
The init-script had started drbd, so I terminate it and it complains:
Failure: (127) MinorNotKnown

--
Then I restart it and it complains:
Failure: (114) Lower device is already mounted.

So I must reboot and when I start drbd, it complains as it did initially:
Failure: (119) No valid meta-data signature found.

The latest snapshot, 2609, seems to still have this problem.
