Hello,

    I am using the Florian step-by-step document to migrate our clusters 
from drbd 0.7.24 to 8.2.0. I had no problem with the test cluster  but 
with one production server I have these error messages for all the 
resource except the first. resource.

[root at ewoks1 i386]# drbdadm create-md "pam"
v08 Magic number not found
v07 Magic number not found
About to create a new drbd meta data block
on /dev/vgroot/lvpam.

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

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

For the resource I can migrate..

[root at ewoks1 i386]# drbdadm create-md squid
WARN:
  You are using the 'drbd-peer-outdater' as outdate-peer program.
  If you use that mechanism the dopd heartbeat plugin program needs
  to be able to call drbdsetup and drbdmeta with root privileges.

  You need to fix this with these commands:
  chgrp haclient /sbin/drbdsetup
  chmod o-x /sbin/drbdsetup
  chmod u+s /sbin/drbdsetup

... (corrected after)

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

Creating meta data...
initialising activity log
NOT initialized bitmap (1280 KB)
New drbd meta data block sucessfully created.

Best regards.

Francis
