    Default ZCS disaster recovery. Error or false positive?

    Hi,

    I'm testing a procedure for disaster recovery. This is what I do:

    I use 'rsync' for synchronize the all /opt/zimbra directory from Master Mail Server to a Backup MailServer.

    rsync -avvrlHKpogD root@<dest-IP-address>:/opt/zimbra /opt


    This is my problem:

    - With ZCS stopped on Master MailServer and on Backup Mail Server, I can sync and than stop the Master, change the IP address and /etc/hosts file on the Backup Mail Server, than start ZCS without any trouble.

    - If I have ZCS on Master MailServer started (that is what I'll want) and stopped on the Backup Mail Server: I can sync and than stop the Master, change the IP address and /etc/hosts file on the Backup Mail Server, but when I start ZCS on Backup MailServer whit "zmcontrol start" , If I check the log, I can see these error:

    zimbra slapd[9138]: bdb_db_open: unclean shut-down detected; attempting recovery.
    zimbra slapd[9138]: slapd starting

    Is this a critical error or false positive, due to the fact that the Master ZCS was up?

    Thanks

    Elisa

    Default

    I think you can't sync a whole /opt/zimbra, from a running Master server, through rsync due to the risk of inconsistency on some DB tables (Mysql, lucene ecc).

    You can try several other ways, but I suggest to wait the native fault tolerance function in the next Zimbra release.....
