CentOS 8.x Zimbra all service status showing down on Zimbra admin interface

It is possible that all services are showing as running in output of below commands:

su - zimbra
zmcontrol status

while on admin interface they appear as down.

To fix it follow below steps:

1. Check the permissions of /var/spool/cron/zimbra file. It should be owned by zimbra and should be 600. If not please run as root user:

   /opt/zimbra/libexec/zmfixperms
   chown zimbra:zimbra /var/spool/cron/zimbra
   chmod 600 /var/spool/cron/zimbra

   Note that running /opt/zimbra/libexec/zmfixperms ( https://wiki.zimbra.com/wiki/Fix_the_Zimbra_Collaboration_Permissions ) does not fixes ownership of zimbra cron file. Hence manually running chown / chmod is required

2. Validate 'zmstatuslog' is configured to run as part of cron using as zimbra user:

   crontab -l | grep zmstatuslog

   There should be a crontab entry executing '/opt/zimbra/libexec/zmstatuslog' every two minutes

3. Restart zimbra stat service using as zimbra user:

   zmstatctl restart
   zmloggerctl restart

4. Look at '/opt/zimbra/log/zmlogswatch.out' file for errors similar to 'illegal attempt to update using time <EpocTime> when last update time is <EpocTime>

   grep -i illegal /opt/zimbra/log/zmlogswatch.out

   1. In case there are illegal attempt related entries in above file use;

      zmloggerctl stop  #Or zmcontrol stop if downtime is available
      mkdir /opt/zimbra/logger/db/data/rrds/old
      mv /opt/zimbra/logger/db/data/rrds/*.rrd /opt/zimbra/logger/db/data/rrds/old/
      zmloggerctl start    #Or zmcontrol start

5. Executed below 3-4 times in continuous succession to get faster updation of service status on admin dashboard as zimbra user:

   /opt/zimbra/libexec/zmstatuslog
   /opt/zimbra/libexec/zmstatuslog
   /opt/zimbra/libexec/zmstatuslog
