    Default [SOLVED] ZCS Restore failure

    Hi there,

    I have taken backups of my production server using the Perl non LVM method from this post:
    Open Source Edition Backup Procedure - Zimbra :: Wiki

    Now I'm trying to restore the zimbra installation to recover some emails that a user deleted onto a another server. I've installed the same host OS (CentOS 5.1) as the initial server.

    Steps taken were based on post: Open Source Edition Backup Procedure - Zimbra :: Wiki

    But instead I get an Error 404 in my browser (admin page or user page). Everything appears to fireup but alas I can't access anything. Browser error quoted here:

    HTTP ERROR: 404

    NOT_FOUND

    RequestURI=/

    Powered by jetty://
    zmcontrol status
    reveals everything is running. A manual
    ps -ef | grep zimbra
    reveals what I expect to be there. Note: /var/log/zimbra.log reports all processes running.

    Zimbra Version on both servers:
    Release 5.0.7_GA_2444.RHEL5_20080626020941 CentOS5
    Are there any generic logs (like a zimbra version of /var/log/messages), I can look into?

    I've checked a few of them but don't see any obvious errors.

    Has anyone come across this?

    I'd appreciate some assistance.
    Thanks,
    KH

    P.S. I'm running a yum update to get my kernel & other package versions the same but this is a fools last resort attempt at fixing it.

    Welcome to the forums

    What happens if you try connecting to the server using its IP address ? If that works okay I would start looking at name resolution.

    Thanks

    It's not a DNS issue. I get the same http response code regardless of using IP or name. It should be noted again though - I get the same error with the user's page as well as the administrator page.

    Other ideas?

    Solved using the following posts with a few additions of chmoding the /opt/zimbra dir to zimbra:zimbra when using the original backup. Note the following: you need the same hostname and mx records pointing to itself. However you don't need the same IP address. Also I didn't need the final localconfig.xml copy. Here's the post: [SOLVED] Same error when recovering, this time on machine with same IP address

    HTTP ERROR: 404

    I'm guessing you followed my previous post. No mention of whether you tried it.

    I have been able to repetitively get it working with the steps from the post referenced above, now below:
    Here are the exact final steps that allowed me to recover from my backup. Honestly, this is pretty much a bad joke that it took all of this.

    1. Backup /opt/zimbra (I tgz'ed it)

    2. Download a fresh tgz of the Zimbra release, preferably the same architecture and version

    3. Install on the new machine, which should have the same DNS and MX settings with the command ./install.sh -s

    4. rm -rf /opt/zimbra

    5. Untar the original backup to /opt/zimbra, and run this:

    su - zimbra
    /opt/zimbra/openldap/sbin/slapcat -f /opt/zimbra/conf/slapd.conf -l /tmp/ldap.ldif


    ****MY Addition****
    chmod zimbra:zimbra /opt/zimbra

    6. Copy the /opt/zimbra/conf/slapd.conf and /opt/zimbra/conf/localconfig.xml to a safe place

    7. rm -rf /opt/zimbra (which will be the backup...make sure you kept the original backup as a tgz so you can unzip it again)

    8. Re-install from the original distribution with the -s option

    9. Copy the backup of slapd.conf to /opt/zimbra/conf

    10. Run this command:

    su - zimbra
    /opt/zimbra/openldap/sbin/slapadd -f /opt/zimbra/conf/slapd.conf -l /tmp/ldap.ldif

    11. Move the /opt/zimbra/openldap-data directory to a safe place

    12. rm -rf /opt/zimbra

    13. Unzip from the backup again

    14. Delete the /opt/zimbra/openldap-data directory

    15. Copy/move the backup of the openldap-data directory into the /opt/zimbra directory

    16. Run /opt/zimbra/libexec/zmfixperms

    17. Run the install.sh without the -s option. It will most likely fail.

    18. Copy the original localconfig.xml into the /opt/zimbra/conf directory

    19. ./install.sh again without the -s option

    20. Just to even it out at a full TWENTY STEPS, write a post to the Zimbra forums complaining what a pathetically convoluted process this was.
    If you follow that exactly - it should work. Also - you need the same hostname and MX records to get it working.

    Other than that, you're not being very specific in any other errors.

    HI,

    I am getting the following error while doing 5th step of above procedure.

    [zimbra@pdcserver ~]$ /opt/zimbra/openldap/sbin/slapcat -f /opt/zimbra/conf/slapd.conf -l /tmp/ldap.ldif
    The first database does not allow slapcat; using the first available one (2)
    bdb_db_open: alock package is unstable
    backend_startup_one: bi_db_open failed! (-1)
    slap_startup failed
    Regards,
    Jay Choksi
