Hello, I’m running openldap 2.3.43 on CentOS
5.3 machine (1 Xeon @2.33GHz, 1.5GB RAM). My LDAP directory contains about 158000
entry (users) loaded from a massive ldif add. I’m using hdb database and I defined a
couple of additional indexes to default configuration. Very often (not every time) I stop the
service and restart I recive this message: hdb_db_open: unclean shutdown detected;
attempting recovery. hdb_db_open: Recovery skipped in read-only
mode. Run manual recovery if errors are encountered. After I recive this message I can’t
contact ldap server and I have to run slapd_db_recover (that takes long time)
to recover db. This is a test environment and at this time
there is no activity on the server (no read/write operations). This is DB_CONFIG file content (/var/lib/ldap/DB_CONFIG): # $OpenLDAP:
pkg/ldap/servers/slapd/DB_CONFIG,v 1.1.2.4 2007/12/18 11:51:46 ghenry Exp $ # Example DB_CONFIG file for use with
slapd(8) BDB/HDB databases. # # See the Oracle Berkeley DB documentation #
<http://www.oracle.com/technology/documentation/berkeley-db/db/ref/env/db_config.html> # for detail description of DB_CONFIG

their -q option). I tried to reduce lg_buffer_size to force
the server write log file more often to avoid possible “lost transaction”
but this isn’t working. Any ideas about the cause of these db corruptios? Thanks a lot, Gabriele |
