Hello everyone, I have a bit of an issue with my ldap database. I have a Zimbra community edition which uses openldap. A server crashed and I am unable to start the ldap services after the reboot. The description of my problem, after some digging about is:
the initial error indicated problem with the ldap Starting ldap...Done. Search error: Unable to determine enabled services from ldap. Enabled services read from cache. Service list may be inaccurate. Having investigated the issue, I noticed the following errors in the zimbra.log slapd[31281]: mdb_entry_decode: attribute index 560427631 not recognized I also noticed that the /opt/zimbra/data/ldap/mdb/db/data.mdb is actually 81Gb in size and had reached the limit imposed by the ldap_db_maxsize variable. so over the weekend, the LDAP mdb file became no longer sparse. I tried following the steps described in https://syslint.com/blog/tutorial/solved-critical-ldap-primary-mdb-database-is-90-full-in-zimbra/ but with no success, as the slapcat segfaults with the following message. /opt/zimbra/common/sbin/slapcat -ccc -F /opt/zimbra/data/ldap/config -b "" -l /opt/zimbra/RECOVERY/SLAPCAT/zimbra_mdb.ldiff 5c583982 mdb_entry_decode: attribute index 560427631 not recognized Segmentation fault (core dumped) the mdb_copy produces a file of 420 mb in size, but it still contains the "mdb_entry_decode: attribute index 560427631 not recognized" error. I've also tried mdb_dump, but had the same issues after using the mdb_load command. I found a post ( http://www.openldap.org/its/index.cgi/Software%20Bugs?id=8360 ) in the openldap community that the mdb gets corrupted if it reaches the maximum defined size. but no solution of how to fix it. any advice on getting the database recovered and working again? Cheers Andrei
