Your OpenLDAP server process slapd does not start any more.
By starting the slapd manually (
/usr/sbin/slapd -h "ldapi:/// ldap://:7389/ ldaps://:7636/") you will get the following error message:
Note: You might use the full debug for starting the slapd but this will print loads of debug messages to your console. Just add “
Jul 02 23:47:37 master091 slapd: Starting ldap server(s): slapd > ...failed. Jul 02 23:47:37 master091 slapd: Bus error Jul 02 23:47:37 master091 slapd: .
As a bus error usually indicates a hardware error you will have to decommission your server and install from scratch on new hardware and re-join.
In case this error appears on a virtual machine your virtual machine filesystem is somehow corrupted. Possibly due to some hardware issues on the host server. You will have to reinstall from scratch and re-join.
If the affected server is an UCS master server you have to perform a backup2master procedure and decommission the previous master server.
