Error Valid backup file not found upgrading from 5.0.18 to 6

[mmorse]

Goal is to create an /opt/zimbra/data/ldap/ldap.bak

sub migrateLdap($) {
my ($migrateVersion) = @_;
if (main::isInstalled ("zimbra-ldap")) {
if($main::configStatus{"LdapMigrated$migrateVersion"} ne "CONFIGURED") {
if (-f "/opt/zimbra/data/ldap/ldap.bak") {
my $infile = "/opt/zimbra/data/ldap/ldap.bak";
my $outfile = "/opt/zimbra/data/ldap/ldap.60";
if ( -s $infile ) {
open(IN,"<$infile");
open(OUT,">$outfile");
while() {
if ($_ =~ /^zimbraPrefStandardClientAccessilbityMode:/) {next;}
if ($_ =~ /^objectClass: zimbraHsmGlobalConfig/) {next;}
if ($_ =~ /^objectClass: zimbraHsmServer/) {next;}
print OUT $_;
}
} else {
main:rogress("Valid backup file not found, exiting.\n");
return 1;
}

A way to generate a LDIF output is a slapcat:

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

We even roll it into a easier utility:

${zimbra_home}/openldap/sbin/slapcat -F ${zimbra_home}/data/ldap/config -b "" -l $DEST/ldap.bak.${D}
cp -f ${DEST}/ldap.bak.${D} ${DEST}/ldap.bak

So run this:

su - zimbra
cd /opt/zimbra/libexec
./zmslapcat /opt/zimbra/data/ldap

Should produce a ldap.bak & ldap.bak.date in /opt/zimbra/data/ldap.

~~~
You don't need to restore but here's how you'd use slapadd:

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

That command would only work in 5.x since in 6.x OpenLDAP now allows for some on-the-fly configuration changes with zmlocalconfig via a cn=config backend instead of slapd.conf text files for preservation across upgrades.
So, if something went wrong it's better to run:

/opt/zimbra/openldap/sbin/slapadd -q -b "" -F /opt/zimbra/data/ldap/config/ -cv -l ldap.bak

Edit: You may have a good ldap.bak.timestamp that's not zero length (caused by running the installer multiple times) to use first rather than taking a new one.

Bug 43591 – ldap.bak issues on GNR upgrades

Quanah also pointed out that depending on when you create this ldap.bak (if your not using one that was created earlier like ldap.bak.timestamp) have to be using the 5.0 slapcat/sleepycatlibs for BDB differences with 6.0 to get a valid backup.

many files ldap.bak and ldap.bak.{DATE} in /opt/zimbra/data/ldap, but his size 0...

Hey

Same here - only zero lenght files created as Backup - error is still there

[Nextasy]

Hmm - has anyone an idea?

[uxbod]

Have you tried the commands that both mmorse and myself have posted ?

[Nextasy]

yes, i have. It creates 2 files named ldap.bak and ldap.bak.$TIMESTAMP in
/opt/zimbra/data/ldap/ - both Files have the size 0.

After that, i started install.sh - and the same error appears. Could not find any valid Backup File

[uxbod]

Has the install script actually updated the core ZCS files ?

I am wondering, as mmorse has said, that due to the changes to the schema etc the command that is being executed in the ZCS6 zmslapcat is failing for some reason when query a V5 LDAP database.

[uxbod]

Okay, try running this

su - zimbra
/opt/zimbra/openldap/sbin/slapcat -F /opt/zimbra/data/ldap/config -b "" -l /opt/zimbra/data/ldap/ldap.bak

Does it just return to the command prompt ? Any errors produced ? Try removing the ldap.bak files from /opt/zimbra/data/ldap first (I would just create a backup directory under there and move the files into it).

[Nextasy]

Has the install script actually updated the core ZCS files ?

Of course - if i run install.sh with the switch "-s" the script ended with no errors.

Okay, try running this

su - zimbra
/opt/zimbra/openldap/sbin/slapcat -F /opt/zimbra/data/ldap/config -b "" -l /opt/zimbra/data/ldap/ldap.bak

Does it just return to the command prompt ? Any errors produced ? Try removing the ldap.bak files from /opt/zimbra/data/ldap first (I would just create a backup directory under there and move the files into it).

ok, it creates a file name ldap.bak with also zero lenght. installation ended after that with the same error
