Sorry for the late answer …

We’ve just upgraded to 1.5.9 and update Bitrate and Remit Hello Interval on «Storage Node» settings page.

The generated command was conform and everythings works great !

Thanks a lot

Hello,

Thanks a lot for all this stuff ! We used it since year start (HP/Dell, a dozen of differents models, 300 computers). We made some minor update on this script, if it can be reused :

# lowercase machine name and remove all spaces
machine=$(echo $machine | tr A-Z a-z | tr -d ' ')

So, our drivers directory looks like :

/images/drivers
├── forAll
├── hpelitedesk800g3twr
├── hpz230towerworkstation
├── optiplex7040
├── optiplex7050
├── optiplex7060
├── optiplex9010
├── optiplex9020
├── optiplex9030aio

Another one concern the drivers download (unicast/NFS) by each client. By default, all unicast rsync start after the last multicast session. To make «subgroups» of rsync based on last IP number:

dots "Calculate IP (wait4sync)"
MY_IP=$(ip route get 9.9.9.9 | awk '{print $7}')
IP_LAST=$(echo ${MY_IP} | cut -f 4 -d '.')

# IP OK ?
if ! [[ ${IP_LAST} =~ ^[0-9]{1,3}$ ]]
then
  IP_LAST=4
  echo -n " bad IP..., use ${IP_LAST},"
fi
# Want each to wait ((IP_LAST % 5) ) * 3mn
## w.x.y.zz0|5|10|... => no wait
## w.x.y.zz1|6|11|... => wait 3mn
## w.x.y.zz2|7|12|... => wait 6mn
WAIT=$((${IP_LAST} % 5 * 3))m
echo " IP: ${MY_IP} => wait ${WAIT}"
sleep ${WAIT}

dots "Preparing Drivers"
...

the last one concern the «forAll» directory, used for all common drivers like «pci simplified communication»:

remotecommondriverpath="/images/drivers/forAll"
[[ ! -d "${clientdriverpath}" ]] && mkdir -p "${clientdriverpath}" >/dev/null 2>&1
dots "Common drivers In Progress"
rsync -aq "$remotecommondriverpath" "$clientdriverpath" >/dev/null 2>&1
[[ ! $? -eq 0 ]] && handleWarning "Failed to download common drivers"
echo "Finish"

We use FOG 1.5.5, Multicast over different VLAN and set --mcast-rdv-address configuration setting.

By default with this setting, udp-receiver (on each client) and a ttl set to 1 can’t reach server.

One workaround is to wait all client reach the partclone screen and then restart the FOGMulticastManager service.

Another one is to ask udp-sender to rebroadcasts the HELLO packet with the --rexmit-hello-interval parameter. With this setting, all receivers are able to find the Fog Server without restarting any service.

Would it be possible to add a field in the multicast settings of the Web UI for extra-options ? (--max-bitrate is useful too )

Actually to add these options we edit fog/lib/service/multicasttask.class.php (line 495)

          $buildcmd = array_values(array_filter($buildcmd));
// Add our options
$buildcmd[]=' --rexmit-hello-interval 5000'; //every 5 seconds
$buildcmd[]=' --max-bitrate 600m';           // max bandwith, no stress for others computers
// End extra options
          switch ($this->getImageType()) {
