ZCS 8.8 IMAPD service

Postby phoenix » Thu Sep 07, 2017 9:43 am

Yes, I know it's beta but in the Release Notes (wiki page).....

1. There's no indication whether this should be installed, or not, from the repo

2. There no indication of how you manage this service nor under what circumstances it should be used

3. There no information about how to remove it if it's actually installed (in error) on a single server

4. I think that including beta feature in a GA release is a good idea but it should have a bit more information about what to do with the service so we can actually test it.

The only information that seems relevant to the feature is in the Beta forum and (from there) in the Admin Guide documentation: https://zimbra.github.io/adminguide/wor ... apd_server

Hi guys,
As per https://zimbra.github.io/adminguide/wor ... apd_server Zimbra IMAPD is an optionally IMAPD server, which is meant to be installed for Service Providers or Customers with big environments where users consume their Mailbox using IMAP.

As per a quick list:
  • If you don't install Zimbra IMAPD, then you will use the actual internal IMAP daemon as usual.
  • If you do miss click and say Y, but you don't configure all the IMAPD upstream, etc as per the guide. Then you will still be using the internal IMAP daemon as usual.
  • Finally, if you select Y, and configure the IMAPD as instructed on the documentation, you will leverage all the features and capabilities of this new distributed IMAP technology.

I hope it's clear enough, I will ask our lead Engineer around IMAP to keep an eye on this topic.

PS: Don't put this on Production, yet.

Thank you!

Jorge is correct. If you just install the package but don't make a particular effort to configure it, it will be ignored.
Like any beta software, I'd recommend it is enabled only in evaluation environments and not in production. We are aware of some issues with it but would welcome any more that you can find so that they get resolved before we certify it for general release.

Thank you both for your replies and I don't put software into production that has no details about what it does. ;) My main concern was that there is no information in the Release Notes on the state of this feature other than 'beta', I expect a beta release to be mostly usable - with the proviso that it may eat your data and crash your servers. I'm also a bit bothered by the lack of details in the notes, you may end up with users that install on a live server and end up with problems, that does no good for your testing. When things have settled down I will probably give this a run on a test server, just for fun.
Regards

Even after reading the 'docs' It's still not clear how to cleanly/safely remove it.

> If you do miss click and say Y, but you don't configure all the IMAPD upstream, etc as per the guide. Then you will still be using the internal IMAP daemon as usual.

"configure all the IMAPD upstream, etc"

That's still fuzzy.

Afaict, this actively DISABLES it,

Code: Select all

zmprov ms `zmhostname` zimbraRemoteImapServerEnabled FALSE

so

Code: Select all

zmprov gs `zmhostname` zimbraImapServerEnabled
   zimbraImapServerEnabled: TRUE
zmprov gs `zmhostname` zimbraRemoteImapServerEnabled
   zimbraRemoteImapServerEnabled: FALSE


It still seems that zmconfig acts differently, still expecting something from 'imapd' after the 885 install:

viewtopic.php?f=13&t=63316

I don't know if that's because of installed-but-disabled-remote-imapd, or something else.
