Hi,

I use cLVM and have this definition:

crm configure show
...
node ha1infra \
attributes standby="off"
node ha2infra \
attributes standby="off"
primitive cluvg1 ocf:heartbeat:LVM \
params volgrpname="cluvg1" \
op start interval="0" timeout="240s" \
op stop interval="0" timeout="100s"
primitive clvm ocf:lvm2:clvmd \
params daemon_timeout="30" \ <--------------- Line (1)
op start interval="0" timeout="240s" \
op stop interval="0" timeout="100s" \
meta target-role="Started"
primitive dlm ocfacemaker:controld \
op monitor interval="120s" \
op start interval="0" timeout="240s" \
op stop interval="0" timeout="100s"
...
...
...
clone cluvg1_clone cluvg1 \
meta interleave="true" target-role="Started" is-managed="true"
clone clvm_clone clvm \
meta globally-unique="false" interleave="true" target-role="started"
clone dlm_clone dlm \
meta globally-unique="false" interleave="true" target-role="started" is-managed="true"

I do not remember why we have the Line(1) and the value 30.
The cluster is running and about 10 Xen VMs are using the clustered VG.

My question is: can I change this parameter smoothly without interrupting
or disturbing the clvmd deamon and the LVs within the clustered VG ?
