I have been continuing further studying
https://www.ateam-oracle.com/post/isv-implementation-details-part-4a-linux-clustering-with-pacemaker-and-corosync
Right now, I got pacemaker and corosync up and running. However, I am stuck
in one part: it seems IPaddr2 couldn't execute external binary:
##### OCI vNIC variables
server="`hostname -s`"
nat1_vnic="ocid1.vnic.oc1.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
nat2_vnic="ocid1.vnic.oc1.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
vnicip="10.0.0.10"
...
...
#
# Add an interface
#
add_interface () {
currentDate=`date`
echo $currentDate >> /home/user1/mylog
echo "Added Interface" >> /home/user1/mylog
##### OCI/IPaddr Integration
if [ $server = "z2-server-nat1" ]; then
echo $nat1_vnic >> /home/user1/mylog
echo $vnicip >> /home/user1/mylog
oocciivv=`/root/bin/oci -v`
echo $oocciivv >> /home/user1/mylog
oouutt1=`/root/bin/oci network vnic assign-private-ip
--unassign-if-already-assigned --vnic-id $nat1_vnic --ip-address $vnicip`
oouutt2=`/bin/systemctl network restart`
echo $oouutt1 >> /home/user1/mylog
echo $oouutt2 >> /home/user1/mylog
echo "z2-server-nat1" >> /home/user1/mylog
else
/root/bin/oci network vnic assign-private-ip
--unassign-if-already-assigned --vnic-id $nat2_vnic --ip-address $vnicip
>> /home/user1/mylog
/bin/systemctl network restart >> /home/user1/mylog
echo "z2-server-nat2" >> /home/user1/mylog
fi
echo "----------" >> /home/user1/mylog
local cmd msg ipaddr netmask broadcast iface label
...
...
After doing some resource moving via:
pcs resource move Cluster_VIP z2-server-nat2
pcs resource move Cluster_VIP z2-server-nat1
I got some results in my /home/user1/mylog file, and it turned out I
/root/bin/oci and /bin/systemctl have no output whatsoever. The log file
got the date, the string "Added Interface", the variable nat1_vnic, the
variable vnicip, a few blank lines (which supposed to be the output of oci
and systemctl) and the string "z2-server-nat1".
In this case, I see that the script is executed, but it seems it cannot run
oci and systemctl for some reasons.
I have also tried creating a testOCI.sh file housing:
echo `/root/bin/oci network vnic assign-private-ip
--unassign-if-already-assigned --vnic-id
ocid1.vnic.oc1.xxxxxxxxxxxxxxxxxxxxxxxxxx --ip-address 10.0.0.10` >>
/home/user1/myLogForSimpleSH
echo `/bin/systemctl network restart` >> /home/user1/myLogForSimpleSH
Here, if I run it directly from the terminal with ./testOCI.sh, I see that
I got the data from oci correctly.
Am I missing something in this case? What is needed for the IPaddr2 file to
run external binaries?
Thank you,
Chariot
