ZCS 5.0.11.2695 Disaster Recovery

[pramod.k29]

Hello All,

We are using ZCS 5.0.11. We have done a disaster recovery step ie, to make an exact replica of the running ZCS server. These are the steps we have done.

1)Installed Zimbra in a local machine with local IP
2)Configured DNS in the same system pointing to the same system ie 172.17.5.11

3)copied the /opt/zimbra folder of the original system ie ,system which is running now with public IP.

4) Copied that /opt/zimbra directory(From the original one) to the local machine after removing the /opt/zimbra of the local one.

5)Started the services using zmcontrol startup

6)All services started without errors.

But when i typed https://mx.mydomain.com:7071

its showing a 404 error with url not found.

URI=/zimbraAdmin.

Also the client interface is not opening up.

Please help me how I can get rid of this issue.

1. have you installed the same Zimbra version?
2. have you run:
chown -R zimbra:zimbra /opt/zimbra
/opt/zimbra/libexec/zmfixperms
3. have you read:
Open Source Edition Backup Procedure - Zimbra :: Wiki

I am using Zimbra 5.0.11.2695.

I have done the following steps correctly
************************************************** ***************************
Disaster Recovery






sudo -u zimbra /opt/zimbra/bin/zmcontrol shutdown
mv /opt/zimbra /tmp/zimbra-old



mkdir /opt/zimbra
tar zxvf [backup file] -C /opt/zimbra

.

tar zxvf [backup file] -C /tmp/zimbra-backup
cp -Rp /tmp/zimbra-backup /opt/zimbra



chown -R zimbra:zimbra /opt/zimbra
/opt/zimbra/libexec/zmfixperms

* Restart all Zimbra services

sudo -u zimbra /opt/zimbra/bin/zmcontrol startup
zmcontrol startup

************************************************** ***********************************

And I am getting the same error URL not found
HTTP ERROR: 404

NOT_FOUND

RequestURI=/

************************************************** ********************************

Is there something I am missing ????

[jorge_s]

Have you checked the hosts file and installed a local dns in the "backup server"?

It is important that they point the domain and it's respective dns to this new server.

Have you tested if the vanilla installation (before you copy your backup to /opt/zimbra/) shows the web interface?

[pramod.k29]

Yes, I My vanilla installation was working fine. Also my DNS is configured without any probs.

And my host file entry containc 172.17.5.11 mx.mydomain.com mx

Before the copying all was working fine.

[pramod.k29]

One more thing, I have rsynced the data from the running server ie rsync -av [my public ip]:/opt/zimbra /opt/zimbra_sync/. Is that a problem????

The server was running live (The orginal server ),Also transactions are being done at the time of rsync
in brief i have rsynced /opt/zimbra directly from a running server...........


is that caused the problem?????

The server needs to be shut down when doing an rsync or the data is not guaranteed to be in a consistent state.

To confirm your DNS is OK you should go to the 'Verify....' section of the Split DNS article and run all the commands there, it also contains details of the requirements for the hosts file. Your 'new' server will also need the same hostname as the original, I'd suggest you read some of the articles in the forums and wiki on what's needed for a Disaster Recovery.

Hello Phoenix,

The root not found was with the Version crash that I have installed a higher version of ZCS 5.0. Now I have installed the same version ,but now i am getting this error msg.
