| INSTALLATION |
| |
| Place files SCSTTarget and SCSTLun into pacemaker ocf directory (usually |
| /usr/lib/ocf/resource.d or /usr/lib64/ocf/resource.d) |
| |
| |
| |
| EXAMPLE OF USAGE |
| |
| Assumptions: |
| - you are using DRBD as backing device (/dev/drbd1) |
| - your target iqn is iqn.2012-02.com.mysuperhasan:vdisk.lun |
| - your nic reserved for iscsi is eth2 and your iscsi subnet is 192.168.103.x |
| |
| This is what your resource configuration in cib notation will look like: |
| |
| primitive DRBD_VOLUME ocf:linbit:drbd \ |
| params drbd_resource="DRBDRESOURCE" \ |
| op monitor interval="29" role="Master" \ |
| op monitor interval="31" role="Slave" |
| primitive ISCSI_IP ocf:heartbeat:IPaddr2 \ |
| params ip="192.168.103.20" cidr_netmask="24" nic="eth2" \ |
| op monitor interval="10s" |
| primitive ISCSI_LUN ocf:scst:SCSTLun \ |
| params target_iqn="iqn.2012-02.com.mysuperhasan:vdisk.lun" lun="0" \ |
| path="/dev/drbd1" handler="vdisk_fileio" device_name="VDISK-LUN10" \ |
| additional_parameters="nv_cache=1" \ |
| op monitor interval="10s" timeout="120s" |
| primitive ISCSI_TGT ocf:scst:SCSTTarget \ |
| params iqn="iqn.2012-02.com.mysuperhasan:vdisk.lun" \ |
| portals="192.168.103.20" \ |
| op monitor interval="10s" timeout="120s" |
| group GR_ISCSI ISCSI_TGT ISCSI_LUN ISCSI_IP |
| ms MS_DRBD_VOLUME DRBD_VOLUME \ |
| meta master-max="1" master-node-max="1" clone-max="2" \ |
| clone-node-max="1" notify="true" |
| colocation CO_ISCSI_ON_DRBD_VOLUME inf: GR_ISCSI MS_DRBD_VOLUME:Master |
| order OR_DRBD_BEFORE_ISCSI inf: MS_DRBD_VOLUME:promote GR_ISCSI:start |
| |
| |
| |
| CURRENT LIMITATIONS |
| |
| Scripts are tested only with straight drbd or lvm over drbd as backing device, |
| using vdisk_fileio, with one lun per target. |
| |
| CHAP authentication is configurable, but not yet tested. My current version of SCST |
| throws an error while adding chap parameters. |
