Moving Email Role

twest

Had anyone on V12 had issues moving their email role?

I don't even use any of Enhance email service, but in an old version it was required to enable the role for phpmail to work. Later it was fixed so that you don't need an email role for servers to send phpmail, but I don't see a way of removing the role from sites it was already assigned.

To further complicate, I initially assigned the role to 1 server to act as the central hub for "all phpmail execution". Later I found that doesn't work and the Email role had to be assigned to every server to enable phpmail.

In V11 I never had an issue moving a websites email role from one server to another, but now the roles seem "stuck". The migrator tool can't migrate them. I will get the error message later if nobody else has this problem.

I wanted to change the role on the remaining sites that have it assigned to a different server than their app/db so that their backups aren't riddled with empty backups due to the email role getting backed up separately (and it's empty, as there's zero mailboxes).

Yes, it’s working fine here, we’ve moved both the email and app roles a couple of times on production clusters since v12 with no issues at all. On our test cluster, we’ve moved the email role dozens of times while testing new cPFence email-related features currently in the works, and everything worked smoothly.

Could you share more about your cluster setup? Role distribution, OS version, web server type, MySQL version, etc. That might help narrow things down.

It's all pretty vanilla setup, only changes are KernelCare to keep the kernel updated without reboots and a lightweight monitor app. Using Ubuntu 22, ELS, MySQL 8.0. Control panel is on a VPS and just hosts the panel, then dedicated servers run app/db.

Grabbed the error message. Now that I'm looking at it more closely, it says it failed "No such file or directory", but that directory actually does exist on both servers.

twest I've had the same error involving the control panel server (in my case from external to the control panel sever) and Adam suggested restarting the PHP container for that website. It worked.
