Setting up the PoolManager configuration

Add all pools, which are planned to be centrally flushed to a PoolGroup, lets say flushPoolGroup :

psu create pool migration-pool-1
psu create pool migration-pool-2
#
psu create pgroup flushPoolGroup
#
psu addto pgroup flushPoolGroup migration-pool-1
psu addto pgroup flushPoolGroup migration-pool-2
#

Setting up the central flush batch file.

Create a batchfile /opt/d-cache/config/hsmcontrol.batch with the following content :

#
set printout default 3
set printout CellGlue none
#
onerror shutdown
#
check -strong setupFile
#
copy file:${setupFile} context:setupContext
#
import context -c setupContext
#
check -strong serviceLocatorHost serviceLocatorPort
#
create dmg.cells.services.RoutingManager  RoutingMgr
#
create dmg.cells.services.LocationManager lm \
     "${serviceLocatorHost} ${serviceLocatorPort}"
#
create diskCacheV111.hsmControl.flush.HsmFlushControlManager FlushManager  \
        "flushPoolGroup \
         -export   -replyObject \
         -scheduler=diskCacheV111.hsmControl.flush.driver.AlternatingFlushSchedulerV1  \
          -driver-config-file=${config}/flushPoolGroup.conf \
        "
#

Change to /opt/d-cache/jobs and run ./initPackage.sh. Ignore possible warnings and error messages. The Script will create the necessary links, mainly the jobs/hsmcontrol startup file. To start the central service run

cd /opt/d-cache/jobs
./hsmcontrol start

This setup will produce quite some output in /var/log/hsmcontrol.log. Reduce the output level if this is not required.

set printout default errors

Setting up the driver properties file

Create a file in /opt/d-cache/config named flushPoolGroup.conf with the content listed below. You may change the content any time. The driver will reload it after awhile.

#
#  trigger parameter
#
max.files=4
max.minutes=10
max.megabytes=200
#
#  time interval between rule evaluation
#
timer=60
#
# which fraction of the pool set should be rdOnly (maximum)
#
max.rdonly.fraction=0.999
#
#  output steering
#
print.events=true
print.rules=true
print.pool.progress=true
print.poolset.progress=true
mode=auto
