Re: contextCSN

[jakjr <joao.alfredo@gmail.com>]

I dont thing so.

I have found some situations where the contextCSN is the same, but the tree are not synced.


I use a simple script to search all entryCSN from all entries and check then against eachother.
 
eg:

#!/bin/sh

date=`date +%Y%m%d-%T`

TMPFILE_1='/tmp/master1'
TMPFILE_2='/tmp/master2'

ldapsearch -LLL -b "<BASE CONTEXT>" -x -h <IP1>  entryCSN>"$TMPFILE_1.full"
ldapsearch -LLL -b "<BASE CONTEXT>" -x -h <IP2> entryCSN>"$TMPFILE_2.full"

sed -i '1,3 d' "$TMPFILE_1.full"
sed -i '1,3 d' "$TMPFILE_2.full"

more "$TMPFILE_1.full" | grep entryCSN > "$TMPFILE_1.tmp"
more "$TMPFILE_2.full" | grep entryCSN > "$TMPFILE_2.tmp"

sort "$TMPFILE_1.tmp" > "$TMPFILE_1.csn"
sort "$TMPFILE_2.tmp" > "$TMPFILE_2.csn"

diff "$TMPFILE_1.csn" "$TMPFILE_2.csn" > "$TMPFILE_2.diff"

DIFFC1=`cat "$TMPFILE_2.diff" | wc -l`

if [ $DIFFC1 -eq 0 ]; then
        echo "OK";
else
        echo "ERR";
        cat $TMPFILE_2.diff
fi

Hello,

Sorry for my English google:)
I'm put into production 2 openldap masters, and I asked the same question João Alfredo.

So, if the resultt of this search is the same on all master's this mean that all servers are consistents, right ?

Ok, the ldapsearch (ldapsearch-x-h Master1 ... and ldapsearch-x-h master2 ...) displays the same values of contextCSN for server ID, but what it proves that they are synchronized?

The question is, why master node, the ldapsearch ContextCSN displays of 2 servers (001 & 002)

Can be put in place a monitoring system to test the replication by performing 2 ldapsearchs, if even then synchronized values.

Merci
