Hello all, I'm a newbie in pacemaker so i need your understanding. I'm testing pacemaker+corosync+drbd+ocfs2+samba in 2 vm using ubuntu server 10.04LTS. I use LVM and created 1 VG called vg0 and 2 LVs called /dev/vg0/lv0_iscsi and lv0_samba. Each lv is used by a DRBD device.
/dev/vg0/lv0_iscsi -> drbd0 /dev/vg0/lv0_samba -> drbd1 drbd0 is formatted with ocfs2 fs and auto mounted on /cluster folder by pacemaker. Both drbd0 on 2 nodes are working in primary mode so they auto mount drbd0 in /cluster. I've used this guide to achieve auto mount of drbd0 device on /cluster using crm: http://docs.bloonix.net/drbd-pacemaker-corosync-ocfs2.html My question is how will achieve the same thing (auto mounting drbd1 this time) using samba on /samba mount point? drbd1 is formatted using ext4 fs. I mean which specific configuration I should make in "crm configure edit" to achieve this. Each samba daemon must be started automatically by pacemaker and alsto stopped by it when primary node is up to avoid corruption (primary/secondary mode). Also there must be a HA ip address which pacemaker will "attach" to each working node when the other node is down. This ip would be the ip that clients will use to access samba shares. My current Pacemaker configuration is: node master-server node slave-server primitive res-DLM ocf:pacemaker:controld \ op monitor interval="15" primitive res-Data ocf:linbit:drbd \ params drbd_resource="cluster-ocfs" \ op monitor interval="14s" role="Master" timeout="15s" \ op monitor interval="15s" role="Slave" timeout="15s" primitive res-FS-data ocf:heartbeat:Filesystem \ params device="/dev/drbd/by-res/cluster-ocfs" directory="/cluster" fstype="ocfs2" options="rw,noatime" \ op monitor interval="15" primitive res-FS-samba ocf:heartbeat:Filesystem \ params device="/dev/drbd/by-res/samba" directory="/samba" fstype="ext4" \ op monitor interval="15" primitive res-O2CB ocf:pacemaker:o2cb \ op monitor interval="15" primitive res-Samba ocf:linbit:drbd \ params drbd_resource="samba" \ op monitor interval="14s" role="Master" timeout="15s" \ op monitor interval="15s" role="Slave" timeout="15s" ms ms-Data res-Data \ meta resource-stickines="100" notify="true" master-max="2" clone-max="2" ms ms-Samba res-Samba \ meta resource-stickines="100" notify="true" master-max="2" clone-max="2" clone clone-DLM res-DLM \ meta globally-unique="false" interleave="true" clone clone-FS-data res-FS-data clone clone-FS-samba res-FS-samba clone clone-O2CB res-O2CB \ meta globally-unique="false" interleave="true" colocation col-DLM-Data inf: clone-DLM ms-Data:Master colocation col-O2CB-DLM inf: clone-O2CB clone-DLM order ord-DLM-O2CB inf: clone-DLM clone-O2CB order ord-Data-DLM inf: ms-Data:promote clone-DLM:start order ord-FS-data inf: clone-O2CB clone-FS-data order ord-FS-samba inf: clone-O2CB clone-FS-samba property $id="cib-bootstrap-options" \ dc-version="1.0.8-042548a451fce8400660f6031f4da6f0223dd5dd" \ cluster-infrastructure="openais" \ expected-quorum-votes="2" \ stonith-enabled="false" \ no-quorum-policy="ignore" \ default-resource-stickiness="1000"
