LDAP doesn't work. Help please

[fpin]

Hi everybody! I'm a new user of Zimbra. Tried to change SMTP port from 25 to 26.
1. modify /opt/zimbra/postfix/conf/master.cf
from: smtp inet n - n - - smtpd
to: 26 inet n - n - - smtpd
2. zmprov mcf zimbraSmtpPort 26
3. zmcontrol stop;zmcontrol start
Done it and after zmcontrol stop my system doesn't up. It looks like something wrong with LDAP
bdb_db_close: txn_checkpoint failed: Invalid argument (22)
I already checked my /etc/hosts (was locked but now - don't)
I can see into my log file

bdb(): unable to initialize mutex: Function not implemented
bdb(): /opt/zimbra/openldap-data/__db.001: unable to initialize environment lock: Function not implemented
bdb_db_open: Database can not be opened, err 38 Restore from backup!
bdb(): DB_ENV->lock_id _free interface requires an environment configured for the locking subsystem
bdb(): txn_checkpoint interface requires an environment configured for the locking subsystem
bdb_db_close: txn_checkpoint failed Invalid argument (22)
backend_startup_one: bi_db_open failed! (38)
bdb_db_close: alock close filed
slapd stoped

Please help!

Welcome to the forums

Have a read of [SOLVED] LDAP / slapd - Database environment corrupt (Issue & Solution) especially the first post from Quanah.

Thank you for "Welcome"! I've already read it and checked my db

#/opt/zimbra/sleepycat/bin/db_recover -h /opt/zimbra/openldap-data/
#

It seems OK but I suspect it didn't work. And the worst point of this is I don't understand what happen. I just reset port for my SMTP server and had the huge problem. I won't be amazing if the db is OK. But sldap doesn't want to up. Have any ideas?

My problem slightly change. Now I have

$ zmcontrol start
Host MyHost
Starting ldap...Done.
FAILED
Failed to start slapd. Attempting debug start to determine error.
bdb_db_close: txn_checkpoint failed: Invalid argument (22)
backend_startup_one: bi_db_open failed! (38)
dbd_db_close: alock_close failed

Check your DNS settings

cat /etc/hosts
cat /etc/resolv.conf
dig domain.com mx
dig server.domain.com
host `hostname` <- note backticks and not double quotes

Remember to replace domain.com with your own

I've alredy done it.

I can see my zimbra server into /etc/hosts and after command dig. The root of problem is anywhere in database. Also I tied to start ldap by sh -x ldap.- nothing

What does it mean bi_db_open failed! (38) ?

[uxbod]

as root you could try

/opt/zimbra/libexec/zmfixperms -extended
su - zimbra
zmcontrol stop
zmcontrol start
