since nearly 2 weeks I'm using Sophos UTM as HA cluster. Before I'm using ASG and Sophos UTM as single node for over 3 years. I updated yesterday to release 9.207.
With the single node I'm very happy but since running the HA option I see a lot of issues. I don't know where to post them because they are HA related and there's no special HA topic. So I post them here:
Recuring error messages of restarting POP3 proxy on the slave node. See https://community.sophos.com/products/unified-threat-management/astaroorg/f/56/t/49681
The internet connection seems to have often little breaks, i. e. when working at astaro.org I get often the error that the page is unaivalable. So I have to reload the page for many times.
My Samsung LED TV can't get access to the internet when the preferred master is running. This node is the original single machine with UTM. When switching to slave node the internet connection works fine. I don't have any error logs on the UTM when the TV couldn't connect to the internet. It gets a reserved internal IP address provided by the UTM via DHCP.
I get every event on the UTM as mail. When running the master on the preferred machine all the mails are send (Up2Date etc.). When switching to the slave node I didn't get these mails. But when logging on to the console or the web UI I get the mail information about successful logins immediately.
Is anyone here in the forum who has the same issues? For the first point mod2402 is experiencing the same, but is there anyone else?
Can anyone provide solutions? The only solution I see for the moment is to break the HA cluster and have two single systems running. Thanks to virtualization I can deactivate the network connection of the second system with the same IP address and for the case of an issue with the first system I can activate them. That's not very nice, because there's no automation and it is breaking the internet connection for a short time but it would be OK. But I don't think that this is the solution. There must be a lot of HA configurations running in professional networks and I can't imagine that the administrators would be happy having such issues, right?
Kind Regards
