Yes, it would be nice. I don't shut down my slaves as often as you do
though. But even so, I feel better when I occassionally run this:
[todd@tlyons ~]$ cat bin/checkldapconsistency.sh
for TARG in master ldap1 ldap2; do
FILE="$(mktemp /tmp/$(basename $0.XXXXXX))"
echo -en "Checking $TARG: \t"
ldapsearch -x -LLL -H ldap://$TARG -b "dc=domain,dc=net" -z 0 -w
obfuscated -D cn=Manager,dc=domain,dc=net "(sendmailMTAMapName=virtuser)"
sendmailMTAKey > $FILE
egrep '^dn:' $FILE | wc -l
rm -f $FILE
[todd@tlyons ~]$ checkldapconsistency.sh
Checking master: 34203
Checking ldap1: 34203
Checking ldap2: 34203
I'm curious, how do you merge the rejects back into your slaves when you
bring them back up the next day? Is that automated somehow? Or do you
manually ldapadd them back in?
We should not be building surveillance technology into standards.
