VMs should be kept running. Services should ideally be stopped before upgrading.

service ha-lizard stop -w
service iscsi-ha stop -w

(FYI - the "-w" flag will no longer work in the latest releases due to systemd compatibility. After upgrading, it will be necessary to stop ha-lizard and iscsi-ha watchdogs before stopping the services themselves)

Thank you @salvatore, after upgrading the commands are the same?

service ha-lizard stop -w
service iscsi-ha stop -w

Don't make much sense... if i stop the services before upgrade, after upgrade must stop them again?

Thanks

The installer will start the services up again automatically when upgrading.

What I meant is that in older versions (pre XS 7), the -w flag could be passed in when starting/stopping the ha-lizard service. This would tell the init script to also start/stop the watchdog service.

Due to systemd's inability to accept additional arguments on the command line, -w is no longer supported. So, in order to stop in the latest release you must first stop the watchdog and then the service itself otherwise it will keep on starting.

I have my next maintenance slot in front of me. Just a quick question, if the installer was updated as mentioned.

I could not see in the release notes a corresponding statement, or am I blind? B)

It's not clear which installer update you are referring to. If you are upgrading an existing 2-node system, you should not use the noSAN installer to perform an upgrade.

You should manually upgrade both ha-lizard and iscsi-ha. Each of these has its own installer included in the package that will handle the upgrade.

In addition to running the installer on top of your existing installation, copy the contents of /scripts/init/ from the tarball and place in /etc/init.d/ since new init scripts have been created. We'll update the installers this week so that this won't be necessary in the future.


Sorry for not being clear enough. I do not refer to the no SAN installer but the above mentioned statement for upgrading an existing install.
