[DRBD-user] DRBD 9 Fencing Bug with pacemaker-2.0.2

[Martin KOECKINGER]

Hello,

we found a bug in the fencing script "/usr/lib/drbd/crm-fence-peer.9.sh" regarding pacemaker 2.0.2. I used DRBD-utils-9.12.0.

In the function "fence_peer_init" is the following command (in our version its line 203):
                : ${master_id=$(set +x; echo "$cib_xml" |
                               sed -ne '/<master /,/<\/master>/ {
                                                   /<master / h;
                                                    /<primitive/,/<\/primitive/ {
                                                      /<instance_attributes/,/<\/instance_attributes/ {
                                                               /<nvpair .*\bname="drbd_resource"/ {
                                                                  /.*\bvalue="'"$DRBD_RESOURCE"'"/! d
                                                                  x
                                                                  s/^.*\bid="\([^"]*\)".*/\1/p
                                                                  q
                                                               };};};}')}

This "sed" command does no longer work, cause the cib.xml structure in pacemaker 2.0.2 is different. It looks like the section "<master" was renamed to "<clone". In my case the following change did fix the issue:
                : ${master_id=$(set +x; echo "$cib_xml" |
                               sed -ne '/<clone /,/<\/clone>/ {
                                                   /<clone / h;
                                                    /<primitive/,/<\/primitive/ {
                                                      /<instance_attributes/,/<\/instance_attributes/ {
                                                               /<nvpair .*\bname="drbd_resource"/ {
                                                                  /.*\bvalue="'"$DRBD_RESOURCE"'"/! d
                                                                  x
                                                                  s/^.*\bid="\([^"]*\)".*/\1/p
                                                                  q
                                                               };};};}')}

I hope this info is helpful for others running in the same issue and maybe someone can create a fix for the next release?
