hdb to mdb
by Dave Macias 03 Jun '21

03 Jun '21

Hello, Saw this link in a recent mail to this list. https://www.openldap.org/doc/admin25/appendix-upgrading.html Looks like hdb would no longer be supported. I googled a bit to see what it would take to move over to mdb and stumbled on this post. https://www.mail-archive.com/openldap-technical@openldap.org/msg25484.html My question is: Is it really that easy? Just replace all my instances of hdb or Hdb with mdp or Mdb respectively? Additionally add “olcDbMaxSize” to my top lavel “olcDatabase={2}hdb,cn=config” ? Then reimport ? Below is a much redacted slapcat of my config. Any input is much appreciated. Thank you, Dave dn: cn=config objectClass: olcGlobal cn: config olcServerID: 1 structuralObjectClass: olcGlobal creatorsName: cn=config modifiersName: cn=config ... ... dn: olcDatabase={2}hdb,cn=config objectClass: olcHdbConfig olcDatabase: {2}hdb structuralObjectClass: olcHdbConfig ... dn: olcOverlay={0}auditlog,olcDatabase={2}hdb,cn=config ... dn: olcOverlay={1}ppolicy,olcDatabase={2}hdb,cn=config ... dn: olcOverlay={2}syncprov,olcDatabase={2}hdb,cn=config ...

Thank you for the reply > > My question is: > > Is it really that easy? > > yes. Make sure that you have back_mdb moduleloaded as well if it's built > as a module. You do have to export your DB via slapcat and then reimport > with slapadd as well. > I dont have back_mdb built as a module... so i'm assuming I dont need to worry about it, yes?? Yes, slapcat/add POST hdb > mdb conversion. Thanks!

Replication between 2.4.x 2.5.x versions
by Nick Milas 02 Jun '21

02 Jun '21

Hello, We are running a (small) number of OpenLDAP instances with v2.4.58. There is a single master and 4 syncrepl consumers (all on CentOS 7 boxes), all running with back-mdb. We are planning our migration from 2.4 to 2.5.x My question: Would it be OK if we migrate our master server to 2.5.latest, and leave consumers to 2.4.58 for a while? Would any implications be expected? Or it is strongly suggested to shutdown all the servers, migrate to 2.5 in parallel and then restart? (Obviously, the latter approach is more demanding in admin and maintenance planning.) Finally: Is there a script or other way to check possible config incompatibilities with 2.5.x (in order to avoid surprises)? (Note: Our master uses cn=config, while consumers still use slapd.conf.) I will appreciate your advice. Thanks, Nick.
