How to sync UP2Date Files to Slave (manually)

Hi Sebastian,

For High Availiability (HA) and cluster units, Up2Dates are applied to one unit at a time. The failover time is minimal as the higher version unit takes over the connection tracking tables to become the new master. The sequence occurs as:

1. Up2date applied to HA slave node
2. Slave node reboots
3. Slave node after reboot takes master control as it has higher version
4. Old master takes slave role and applies up2date
5. Old master reboots 
6. HA pair is synchronized again and resumes normal operation The High availability status view will show the state of the units during the Up2Date process

Hope that helps.

Thanks

Hi Sachin,

thanks for your answer, but I think you misunderstood my question... I didn´t want to know how the normal update procedure works (I´m pretty familiar with it), I wanted to know, how I can force the sync process of the .gpg files between the two nodes.... For the installation the update packages must be available on both machines. And I want to know, which process is responsible for the synchronization of these files and how I can trigger this manually.

Thanks

Hi Sebastian,

The service responsible for sync process in HA is "repctl".

Generally, sync process will initiate on every configuration changes on the Master Appliance. Forcing a sync process is not suggested as it is an automatic behavior of UTM.

Thanks

Hi Sachin,

ok, then my question is, what causes the repctl process to sync the files between the two nodes? Lets assume I upload an .gpg file, when does repctl sync the file to the other node? Is it time based / periodically? So does repctl stats certain folders for its content and then sync´s this files?

Would be interesting for me to knowhow how it works...

I've had to do this before, but I had no choice, Sebastian.  It's been almost two years since I've done this, so I'd just do it the normal way if possible.  Proceed at your own risk...

Once you have uploaded the gpg files to the Master (the normal, manual way in WebAdmin, not from the command line), you can transfer the files to the Slave.  As root on the Master (the following assumes that the Master has the Node 1 IP, 192.168.250.1 - if not, use the .1 IP and reverse the Node numbers in the following):

cd /var/up2date/sys
rsync -avz *.gpg -e ssh loginuser@198.19.250.2:/home

And then run the Up2Date on the Slave with:

ha_utils ssh
su -
cd /var/up2date/sys
mv /home/*.gpg ./
/sbin/auisys.plx --rpmargs --force

Finally, after the Up2dDates have been applied to Node 2, run the Up2Date on the new Slave (Node 1) with:

ha_utils ssh
su -
cd /var/up2date/sys
/sbin/auisys.plx --rpmargs --force
