Accordingly, we have created a new resource agent named "lvmlockd" # to manage lvmlockd daemon. In addition, this new resource agent "LVM-activate" # is created to take care of LVM activation/deactivation work. This agent supports # the new features: lvmlockd and system ID, and also supports the old features: # clvmd and lvm tag. # # Thanks David Teigland! He is the author of these LVM features, giving valuable # idea/feedback about this resource agent. ############################################################################ # Initialization: : ${OCF_FUNCTIONS_DIR=${OCF_ROOT}/lib/heartbeat} . ${OCF_FUNCTIONS_DIR}/ocf-shellfuncs # Parameter defaults OCF_RESKEY_vgname_default="" OCF_RESKEY_lvname_default="" OCF_RESKEY_vg_access_mode_default="" OCF_RESKEY_activation_mode_default="exclusive" OCF_RESKEY_tag_default="pacemaker" OCF_RESKEY_partial_activation_default="false" : ${OCF_RESKEY_vgname=${OCF_RESKEY_vgname_default}} : ${OCF_RESKEY_lvname=${OCF_RESKEY_lvname_default}} : ${OCF_RESKEY_vg_access_mode=${OCF_RESKEY_vg_access_mode_default}} : ${OCF_RESKEY_activation_mode=${OCF_RESKEY_activation_mode_default}} : ${OCF_RESKEY_tag=${OCF_RESKEY_tag_default}} : ${OCF_RESKEY_partial_activation=${OCF_RESKEY_partial_activation_default}} # If LV is given, only activate this named LV; otherwise, activate all # LVs in the named VG.

It supports the following modes, controlled by the vg_access_mode parameter: * lvmlockd * system_id * clvmd * tagging Notes: 1. There are two possible configuration combinations: lvmlockd+LVM-activate and clvm+LVM-activate. However, it is not possible to use both at the same time! 2. Put all "lvmlockd"/"clvmd" volume groups into auto management by the agent if using the cluster to manage at least one of them. If you manage some manually, the stop action of the lvmlockd agent may fail and the node may get fenced, because some DLM lockspaces might be in use and cannot be closed automatically. 3. The autoactivation property of volume group will be disabled when vg_access_mode is set to system_id. Option: OCF_CHECK_LEVEL The standard monitor operation of depth 0 checks if the VG or LV is valid. If you want deeper tests, set OCF_CHECK_LEVEL to 10: 10: read first 1 byte of the underlying device (raw read) If there are many underlying devs in VG, it will only read one of the devs. This is not perfect solution for detecting underlying devices livable. e.g. iscsi SAN IO timeout will return EIO, and it makes monitor failed. This agent activates/deactivates logical volumes. The volume group name. The volume group name If set, only the specified LV will be activated. Only activate the given LV This option decides which solution will be used to protect the volume group in cluster environment. Optional solutions are: lvmlockd, clvmd, system_id and tagging. The VG access mode The activation mode decides the visibility of logical volumes in the cluster. There are two different modes: "shared" for cluster filesystem and "exclusive" for local filesystem. With "shared", an LV can be activated concurrently from multiple nodes. With "exclusive", an LV can be activated by one node at a time. This option only has effect on "lvmlockd"/"clvmd" vg_access_mode. For "system_id" and "tagging", they always mean exclusive activation. Logical volume activation mode The tag used for tagging activation mode. The tag used for tagging activation mode If set, the volume group will be activated partially even with some physical volumes missing. It helps to set to true when using mirrored logical volumes. Activate VG partially when missing PVs END } ####################################################################### usage() { cat </dev/null | tr -d \') export ${kvs} vg_locktype=${LVM2_VG_LOCK_TYPE} vg_clustered=${LVM2_VG_CLUSTERED} vg_systemid=${LVM2_VG_SYSTEMID} vg_tags=${LVM2_VG_TAGS} # We know this VG is using lvmlockd if the lock type is dlm. if [ "$vg_locktype" = "dlm" ]; then access_mode=1 elif [ "$vg_clustered" = "clustered" ]; then access_mode=2 elif [ -n "$vg_systemid" ]; then SYSTEM_ID=$(lvm systemid 2>/dev/null | cut -d':' -f2 | tr -d '[:blank:]') access_mode=3 elif [ -n "$vg_tags" ]; then # TODO: # We don't have reliable way to test if tagging activation is used. access_mode=4 else access_mode=0 fi return $access_mode } # TODO: All tagging activation code is almost copied from LVM RA!!! # But, the old LVM RA just uses the ordinary tags, not the "hosttag" feature # which may be a better method for active-inactive cluster scenario. # # We have two choice: # 1.
