Hi I have been playing with DRBD, thats cool
But I have 2 VM RHEL linux boxes. They each have a boot device (20g) and a shared ISCSI 200G volume. I've played with ucarp and have the commands to make available/mount the disk and dismount the shared disk using vgchange/mount/umount, etc. But decided to user packemaker/heartbeat, since it is more robust Got corosync running, vip running. But I do not see how to make the Pacemaker section mount or dismount a STANDARD EXT3 disk shared. I've seen tons of tutorials for drbd and clustered FS but none showing a simple mount of a disk as a resouce on a node becoming master, or how to dismount it. Does pacemaker run a script if requested? Or is the mount/dismount all hard-coded. I know I'm missing something simple here. I built the following, but the colocation and order commands error out as syntax error: node prodmessage1v node prodmessage2v primitive p_fs_data ocf:heartbeat:Filesystem \ params device="/dev/mapper/vg2-dbdata" directory="/data" fstype="ext3" primitive p_ip ocf:heartbeat:IPaddr2 \ params ip="10.64.114.80" cidr_netmask="32" \ op monitor interval="30s" primitive p_ping ocf:pacemaker:ping \ params name="p_ping" host_list="10.64.114.47 10.64.114.48 10.64.114.4" \ op monitor interval="15s" timeout="30s" primitive p_rhap lsb:rhapsody \ op monitor interval="60s" timeout="120s" group g_cluster_services p_ip p_fs_data p_rhap clone c_ping p_ping \ meta globally-unique="false" location loc_ping g_cluster_services \ rule $id="loc_ping-rule" -inf: not_defined p_ping or p_ping lte 0 colocation colo_mnt_on_master inf: g_cluster_services order ord_mount_after_drbd inf: g_cluster_services:start property $id="cib-bootstrap-options" \ dc-version="1.0.10-da7075976b5ff0bee71074385f8fd02f296ec8a3" \ cluster-infrastructure="openais" \ expected-quorum-votes="2" \ stonith-enabled="false" \ no-quorum-policy="ignore" rsc_defaults $id="rsc-options" \ resource-stickiness="100" PHIL HUNT AMS Consultant phil.h...@orionhealth.com P: +1 857 488 4749 M: +1 508 654 7371 S: philhu0724 www.orionhealth.com _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://developerbugs.linux-foundation.org/enter_bug.cgi?product=Pacemaker
