[DRBD-user] After a upgrade to v8 it says: (115) Meta device is already mounted.

[Esben Laursen]

Hi List,

I have upgraded my drbd v0.7 to v8 and now when I try and start the 
service it says:

[root at rtsan01 ~]# /etc/init.d/drbd start
Starting DRBD resources:    [ d0 Failure: (115) Meta device is already 
mounted.

cmd /sbin/drbdsetup /dev/drbd0 disk /dev/sdb1 /dev/sdb1 flexible 
--set-defaults --create-device --on-io-error=detach  failed!

If I change to metadata internal, insted of flexible-metadata internal 
it says that I have to create a new metadata with drbdadm create-md res, 
but wount that delete the data I already have on the disk?

Hope that you guys can help me

Cheers

Esben
