Hi,
I changed my config from internal to external meta-data. There is no
important data on the drbd device, so I'm not worried about old (meta)
data.
I created a raid 1 device /dev/md1 on both server. I couldn't find
anything about meta-data on a raid device, but I found some postings with
meta-data on lvm.
/proc/mdstat
md1 : active raid1 sda3[0] sdb3[1]
1975872 blocks [2/2] [UU]
Afterwards I changed the drbd.conf file for all 3 resources on both server.
..
meta-disk /dev/md1 [0];
...
meta-disk /dev/md1 [1];
...
meta-disk /dev/md1 [2];
But now drbd does not start at all - no error messages.

Is there something I have to do if I move the meta-data from internal to
external? I don't want to keep the data, I'm starting from scratch. Is
the md device a problem?
