I’m struggling to understand how to fully exploit the capabilities of targetcli using the Pacemaker resource agent for iSCSILogicalUnit. From this block of code:
lio-t) # For lio, we first have to create a target device, then # add it to the Target Portal Group as an LU. ocf_run targetcli /backstores/block create name=${OCF_RESOURCE_INSTANCE} dev=${OCF_RESKEY_path} || exit $OCF_ERR_GENERIC if [ -n "${OCF_RESKEY_scsi_sn}" ]; then echo ${OCF_RESKEY_scsi_sn} > /sys/kernel/config/target/core/iblock_${OCF_RESKEY_lio_iblock}/${OCF_RESOURCE_INSTANCE}/wwn/vpd_unit_serial fi ocf_run targetcli /iscsi/${OCF_RESKEY_target_iqn}/tpg1/luns create /backstores/block/${OCF_RESOURCE_INSTANCE} ${OCF_RESKEY_lun} || exit $OCF_ERR_GENERIC if [ -n "${OCF_RESKEY_allowed_initiators}" ]; then for initiator in ${OCF_RESKEY_allowed_initiators}; do ocf_run targetcli /iscsi/${OCF_RESKEY_target_iqn}/tpg1/acls create ${initiator} add_mapped_luns=False || exit $OCF_ERR_GENERIC ocf_run targetcli /iscsi/${OCF_RESKEY_target_iqn}/tpg1/acls/${initiator} create ${OCF_RESKEY_lun} ${OCF_RESKEY_lun} || exit $OCF_ERR_GENERIC done fi ;; it looks like I’m only permitted to create a block backstore. Critically missing, in this scenario, is the ability to create fileio backstores on things like mounted filesystems abstracted by things like drbd. Additionally (and this is just a failing on my part), I’m unclear as to where the resource agent is fed the value for “${OCF_RESOURCE_INSTANCE}” given the limited number of parameters one is permitted to supply with “pcs resource create…” Can anyone provide any insight please?
