6. Initiate Data/Storage Partition
Change Line 53 in /etc/lvm/lvm.conf on all nodes:
filter = [ "a/.*/" ]to
filter = [ "a|drbd1[0-9]|", "r|.*|" ]
Initiate data Partition:
NOTE: it's important to use the stacked resource device like you done it with the meta partition!
root@filer01 ~# pvcreate /dev/drbd11
root@filer01 ~# vgcreate data /dev/drbd11
root@filer01 ~# lvcreate -L 400M -n filer data
7. Create Final Heartbeat Configuration
Change /meta/opt/openfiler/etc/cluster.xml on filer01:
<?xml version="1.0" ?><cluster><clustering state="on" /><nodename value="filer01" /><resource value="MailTo::it@company.com::ClusterFailover"/><resource value="IPaddr::10.10.11.100/24/eth0" /><resource value="IPaddr::10.10.50.100/24/eth1" /><resource value="drbdupper::meta-U"><resource value="drbdupper::data-U"><resource value="LVM::data"><resource value="Filesystem::/dev/drbd10::/meta::ext3::defaults,noatime"><resource value="MakeMounts"/></cluster>
Go to https://10.10.11.101:446 and start/stop iscsi target service ( this will recreate/etc/ha.d/haresources onfiler01 ).
Copy haresources to filer02:
root@filer01 ~# scp /etc/ha.d/haresources root@filer02:/etc/ha.d/haresources
8. Enable/Disable System Services
We disable the services that are handled by heartbeat in the configuration:
root@filer01 ~# chkconfig --level 2345 heartbeat on
root@filer01 ~# chkconfig --level 2345 drbd on
root@filer01 ~# chkconfig --level 2345 openfiler off
root@filer01 ~# chkconfig --level 2345 open-iscsi off
root@filer02 ~# chkconfig --level 2345 heartbeat on
root@filer02 ~# chkconfig --level 2345 drbd on
root@filer02 ~# chkconfig --level 2345 openfiler off
root@filer02 ~# chkconfig --level 2345 open-iscsi off
root@filer03 ~# chkconfig --level 2345 drbd on
root@filer03 ~# chkconfig --level 2345 openfiler off
root@filer03 ~# chkconfig --level 2345 open-iscsi off
9. Test Failover On node1 And node2
NOTE : ALL DISCS SHOULD BE IN SYNC BEFORE DOING THIS!
Start heartbeat on node 2:
root@filer02 ~# service heartbeat start
Shutdown node 1:
root@filer01 ~# shutdown -h now
Watch /var/log/ha-log on filer02:
root@filer02 ~# tail -n 50 /var/log/ha-log
Check if you can login on https://10.10.11.100:446.
Start filer01 and do a manual failover:
root@filer01 ~# /usr/lib/heartbeat/hb_takeover
