Re: syncrepl_del_nonpresent and syncrepl issues.




Sounds to me like you haven't properly tuned your database then. I
suggest you read up on properly tuning a DB_CONFIG file (and possibly
using a shared memory key as part of that), and I'm guessing you didn't
use the -q flag with slapadd?


That is entirely possible, I'm entirely self-taught on LDAP.

I have the DB_CONFIG lines in slapd.conf so that they are automatically put into DB_CONFIG file. I just assumed that slapadd would do that. (Just tested, and it does).

I did not use -q.

# time slapadd -q -f slapd-import.conf -l ../full-dump.txt
bdb_monitor_db_open: monitoring disabled; configure monitor database to enable
*##                    10.41% eta 49m44s elapsed          05m46s spd   1.5 M/s

That could be done in a maintenance window of 2 hours at very least.

Is then the official OpenLDAP policy is to do that, even though having 2.4 syncrepl from 2.3 would 'mean less than 5 minutes down-time' ? Clearly that part is attractive to me at 3am..


For amusement sake, /tmp import on the x4540:

-##                    10.08% eta 10m24s elapsed          01m09s spd   2.0 M/s



And the DB_CONFIG settings:

dbconfig set_lk_detect DB_LOCK_DEFAULT
dbconfig set_lg_max 52428800
dbconfig set_cachesize 0 67108864 1
dbconfig set_flags db_log_autoremove
dbconfig set_lk_max_objects 1500
dbconfig set_lk_max_locks 1500
dbconfig set_lk_max_lockers 1500
