Hi,
I'm working on a 2-node active/passive iSCSI storage cluster.
(I follow the guide from linbit)
All works fine, except when active server goes offline, in this case
the iSCSI target (ocf:heartbeat:iSCSITarget) can't stop and flood my
syslog with this line :
"lrmd: [1405]: info: RA output: (p_iSCSItarget_vm-storage:stop:stderr)
Device or resource busy."
The fact that the resource is busy is normal 'cause this target is in use.
I'm on Ubuntu Server 12.04 x64 using iscsitarget (iet) implementation.
below my crm configure :
primitive p_LUN_vm-storage_lun ocf:heartbeat:iSCSILogicalUnit \
params implementation="iet"
target_iqn="iqn.2012-07.fr.domain:storage.vms" lun="1"
path="/dev/drbd0" \
op start interval="0" timeout="10s" \
op stop interval="0" timeout="10s" \
op monitor interval="10s" timeout="10s" depth="0"
primitive p_drbd_vm-storage ocf:linbit:drbd \
params drbd_resource="vm-storage" \
op monitor interval="19" role="Master" \
op monitor interval="21" role="Slave"
primitive p_iSCSItarget_vm-storage ocf:heartbeat:iSCSITarget \
params implementation="iet" iqn="iqn.2012-07.fr.domain:storage.vms"
additional_parameters="DefaultTime2Retain=60 DefaultTime2Wait=5" \
op monitor interval="10s" \
meta target-role="Started"
primitive p_vip_internal ocf:heartbeat:IPaddr2 \
params ip="192.168.1.100" cidr_netmask="24" broadcast="192.168.1.255"
nic="bond1" iflabel="intVIP" \
op monitor interval="7s"
primitive p_vip_pedago ocf:heartbeat:IPaddr2 \
params ip="10.130.162.240" cidr_netmask="24" broadcast="10.130.162.255"
nic="bond2" iflabel="pedaVIP" \
op monitor interval="5s"
group g_VIPs p_vip_internal p_vip_pedago
group g_vm-storage p_iSCSItarget_vm-storage p_LUN_vm-storage_lun
ms ms_drbd_vm-storage p_drbd_vm-storage \
meta master-max="1" master-node-max="1" clone-max="2" clone-
node-max="1" notify="true"
colocation c_VIPs_on_vm-storage inf: g_VIPs g_vm-storage
colocation c_vm-storage_on_drbd0 inf: g_vm-storage ms_drbd_vm-
storage:Master
order o_drbd0_before_vm-storage inf: ms_drbd_vm-storage:promote
g_vm-storage:start
order o_vm-storage_before_VIPs inf: g_vm-storage g_VIPs:start
property $id="cib-bootstrap-options" \
dc-version="1.1.6-9971ebba4494012a93c03b40a2c58ec0eb60f50c" \
cluster-infrastructure="openais" \
expected-quorum-votes="2" \
stonith-enabled="false" \
no-quorum-policy="ignore" \
default-resource-stickiness="200" \
last-lrm-refresh="1343050159"
If anybody have an idea to force iSCSITarget to stop even if the
resource is busy, i will appreciate.
Regards,
Bruno
