Is anyone using Live Sync with Zimbra 8.8.8?

Post by fs.schmidt »

Hello,

We are considering to use the Server Live Sync (https://wiki.zimbra.com/wiki/Server_Live_sync) on an environment. Is anyone using it with Zimbra 8.8.8?

Kind regards.

Hello,
Just try it and let us know your problem if any.
I haven't used it in production but I already tested it on zimbra 8.8 and it ran OK.

Hi,

How did your tests go? I tried to set up live sync on a Zimbra 8.8.8 server, but could only get redolog sync working once every time I start the live_syncd script. After that only LDAP sync continues, while redolog seems to stop.

1. live_sync.log during initial startup: everything works fine at first:-

Fri Jul 27 08:37:34 +08 2018 :Syncing /opt/zimbra/redolog/redo.log
Fri Jul 27 08:37:35 +08 2018 :Syncing /opt/zimbra/redolog/redo.log done
Fri Jul 27 08:37:35 +08 2018 :Syncing redologs done
Fri Jul 27 08:37:35 +08 2018 :Purging redolog directory and archives
Fri Jul 27 08:37:35 +08 2018 :Purge redolog directory and archives done
Fri Jul 27 08:37:38 +08 2018 :Replaying redologs...
Fri Jul 27 08:37:56 +08 2018 :Replaying redologs done
Fri Jul 27 08:37:56 +08 2018 :Live streaming redolog
Fri Jul 27 08:38:01 +08 2018 :Live streaming redolog established
Setting up watches. Beware: since -r was given, this may take a while!
Watches established.

2. After this initial startup, I monitor the live sync status using the nagios script given:-

watch /usr/local/scripts/check_zimbra_live_sync -w 1 -c 2

and at first it syncs OK (OK : Live sync up to date) but after an hour it outputs:-
Warning : redo_replay(1 hours),redo_sync(1 hours),redo_stream(1 hours)

3. Upon checking live_sync.log , redolog no longer syncs since its initial startup, only LDAP sync runs in a loop as follows:-

Fri Jul 27 08:46:45 +08 2018 :Start new LDAP monitor period
Fri Jul 27 08:56:45 +08 2018 :Start new LDAP monitor period
/opt/zimbra/data/ldap/mdb/db/ CLOSE_WRITE,CLOSE lock.mdb
Fri Jul 27 09:06:45 +08 2018 :Syncing ldap using ldif
5b5a702a ldif_read_file: checksum error on "/opt/zimbra/data/ldap/config/cn=config/olcDatabase={0}config.ldif"
Connection refused (Connection refused)
usage: zmhsm <options>
-a,--abort Abort the current HSM session.
-h,--help Displays this help message.
-s,--server <arg> Mail server hostname. Default is localhost.
-t,--start Start the HSM process.
-u,--status Get status on the last HSM session.
5b5a702e ldif_read_file: checksum error on "/opt/zimbra/data/ldap/config/cn=config/olcDatabase={0}config.ldif"
Fri Jul 27 09:07:00 +08 2018 :Syncing LDAP done
......

Would appreciate any clues.

Thanks.

Hi All,

I am using the Live Sync with zimbra 8.8.9 for a test server and as per the wiki, it is working perfectly. But I am facing one challenge, when I login on the second server which had got the data synced from the primary server, all emails becomes unread.

Also It there any way to disable the mailstore sync. I have a redundant storage and I wanted to mount it on both the servers to use the same mail storage. It is just for testing so performance is not an issue.

Regards
