Hello list,
I have an ***old*** Ubuntu-8.04 running 2.4.9. I know, this is old, but there are no security issues here. This slapd contains a small database which is modified rarely. OTOH, there are many read operations. The backend is hdb. As these boxes are running on a CF-disk I'd like to limit disk writes, but when the database is queried, the backend is being updated (slapd started at 11:25, read operation at 11:31):
# ls -altr /var/lib/ldap/ total 768 drwxr-xr-x 3 root root 4096 2013-11-11 20:28 .. -rw-r--r-- 1 openldap openldap 96 2017-11-08 09:36 DB_CONFIG -rw------- 1 openldap openldap 8192 2017-11-08 11:25 objectClass.bdb -rw------- 1 openldap openldap 8192 2017-11-08 11:25 dn2id.bdb -rw------- 1 openldap openldap 123193 2017-11-08 11:25 log.0000000001 -rw------- 1 openldap openldap 65536 2017-11-08 11:25 id2entry.bdb drwx------ 2 openldap openldap 4096 2017-11-08 11:25 . -rw-r--r-- 1 openldap openldap 2048 2017-11-08 11:25 alock -rw------- 1 openldap openldap 24576 2017-11-08 11:31 __db.005 -rw------- 1 openldap openldap 565248 2017-11-08 11:31 __db.004 -rw------- 1 openldap openldap 98304 2017-11-08 11:31 __db.003 -rw------- 1 openldap openldap 2629632 2017-11-08 11:31 __db.002 -rw------- 1 openldap openldap 8192 2017-11-08 11:31 __db.001
Is there a way to limit these disk writes? I didn't touch the standard Ubuntu settings, except for the usual settings like SSL.
Richard.
