[Linux-HA] Heartbeat and DRBD

[Swetha -]

Hello,
   
  I have 2 nodes with heartbeat version-2.0.4 and DRBD version-0.7.21 and iam using RHEL4 as my language.
   
  I have primary/secondary configuration.
   
  I want to update my system from version-0.7.21 to 8.2.4 directly,for that
   
  1.What all packages do i need?
  2.What is the step by step procedure to update the version using RHEL4?
  3.How can i check the data integrity of my primary and secondary?
   
  Regards,
  Jerryaru

Thanks.

I addedd the following lines to the cib.xml

And then these for the filesystem:











value="/usr/local/DATA"/>






When I try to add the constraints (as in: 
http://www.linux-ha.org/DRBD/HowTov2):

drbd.add3 file:
to_action="promote"/>
from="fs0" score="infinity"/>

cibadmin -C -V -o constraints -x drbd.add3

I receive the following error:

cibadmin[14401]: 2008/02/18_12:10:22 ERROR: parse_xml: Ignoring trailing 
characters in XML input.
cibadmin[14401]: 2008/02/18_12:10:22 ERROR: parse_xml: Parsed 95 
characters of a possible 190. Trailing text was: '

If I start only the drbd resource it works fine, when I try to start the 
filesystem resource I receive an error about a not possible mount.

Can anyone help to sort this out?

TIA for help.

cib.xml follows:
