While applying today's updates on a machine running a slapd server, the following error occurred: Stopping slapd: [ OK ] Checking configuration files for slapd: [FAILED] bdb(dc=linuxdev,dc=datasphere,dc=ch): Build signature doesn't match environment bdb_db_open: database "dc=linuxdev,dc=datasphere,dc=ch" cannot be opened, err -30971. Restore from backup! backend_startup_one (type=bdb, suffix="dc=linuxdev,dc=datasphere,dc=ch"): bi_db_open failed! (-30971) slap_startup failed (test would succeed using the -u switch) stale lock files may be present in /var/lib/ldap[WARNING] /var/lib/ldap / / as a result, the ldap server is not running anymore, I cannot start it manually and I have no recent backup. I cannot even use slapcat (after update) on the current data. This is quite urgent since ldap data are heavily used by our applications. Please help !
