This is not a statement about OpenLDAP 2.5.5 itself. - This is my private work not related to the OpenLDAP nor the openSUSE projects => blame me if something looks wrong with the packaging. - If unsure install openldap-ms, not openldap2. This uses a separate prefix /opt/openldap-ms. Ciao, Michael.

So therefore i dont need to worry about back_mdb since it’s already loaded. Yes?

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.

LMDB MAP_LOCK flag on readers to minimize major page faults
by Vitaly Zuevsky 31 May '21

31 May '21

Hi MAP_LOCK flag to mmap() on LMDB readers should populate page cache from the file being mapped and preclude those pages from eviction. I was wondering if that was ever tested, especially with frequent writes to the underlying file. And is there a standard way (a compile option) to include that flag without modifying source code directly? I see quite a few major faults with perf stat, and I am looking if they could be avoided. I am new to LMDB and I guess this discussion may have taken place before, if you could point me out to the right place.. Thank you. Vitaly
