    ZeXtras 2.10.0 install 'error'

    I've just installed the latest version of ZeXtras and it's thrown the following error in a notification email:


    Code:
    The following optional sub-services failed to start:
    - cluster: Unable to initialize ZeXtras Suite cluster
    I'm assuming that's because I have a single server and this doesn't start on that configuration, am I correct?
    Regards

    Hi Bill,

    as always you are on first line


    As you said you shouldn't need the cluster initialization but we have to check this pretty common case.

    Can you please share the output of these commands:

    Code:
    $ zxsuite config getServices
    
            services                                
                module                                  
                    could_start                                                 false
                    could_stop                                                  true
                    running                                                     true
                cluster                                 
                    could_start                                                 false
                    could_stop                                                  true
                    running                                                     true

    Code:
    # ls  -l /opt/zimbra/conf/zextras/cluster_config/
    Thanx for your feedback.

    Hi D0s0n

    Those commands give me the following output:

    Code:
    [zimbra@mail01 ~]$ zxsuite config getServices
    
            services                                
                module                                  
                    could_start                                                 false
                    could_stop                                                  true
                    running                                                     true
                cluster                                 
                    could_start                                                 true
                    could_stop                                                  false
                    running                                                     false
    
    
    [zimbra@mail01 ~]$ ls  -l /opt/zimbra/conf/zextras/cluster_config/

    Hello Bill!

    I'm checking this with the Dev Team, could you please also post the section of the mailbox.log right after the post-installation service restart? You should find something like this:

    Hi Cine

    The stacktrace is quite large, about (72,000 characters) for the forums is there an email address that I can send it to?
    Regards

    Hello Bill!

    I've got an answer from the Devs:

    It seems like TLSv1.3 was manually added in zimbraMailboxdSSLProtocols, which is unsupported by java, and so the cluster initialization fails since the cypher is not available (the protocol was finalized in August 2018 and will be supported only in java 11- https://bugs.java.com/view_bug.do?bug_id=8145252)

    <attr id="1657" name="zimbraMailboxdSSLProtocols" type="string" cardinality="multi" optionalIn="globalConfig,server" flags="serverInherited" requiresRestart="mailbox" since="8.6.0">
    <globalConfigValue>TLSv1</globalConfigValue>
    <globalConfigValue>TLSv1.1</globalConfigValue>
    <globalConfigValue>TLSv1.2</globalConfigValue>
    <globalConfigValue>SSLv2Hello</globalConfigValue>
    <desc>List of SSL/TLS protocols (as documented by SunJSSE Provider Protocols and used in setEnabledProtocols) to be enabled in Jetty for HTTPS, IMAPS, POP3S, and STARTTLS (including LMTP)</desc>
    </attr>

    To check the configuration:

    zmprov gs $(zmhostname) zimbraMailboxdSSLProtocols
    zmprov gcf zimbraMailboxdSSLProtocols

    Does this sound applicable to your infrastructure?

    Hi Cine

    My apologies for the late reply, I didn't see this messages.

    Bingo! You've found this months deliberate error. That's exactly the problem, I thought I was testing this on my test server not the live one and it's been removed now. Sorry for the false alarm and thanks for your quick answer, as usual.
    Regards


    Bill
