How to check and increase size of translog database
Note: This does not apply to UCS prior to version UCS 4.3.3 - errata428. In these versions there is no such database “
Note2: This applies only to 64bit versions of UCS. On 32bit versions the translog uses a Berkeley Database instead, which is only limited by the size of the underlying partition.
Verify the current use of the database.
To check if your databases has reached the value.
used_pages=$(mdb_stat -e /var/lib/univention-ldap/translog | sed -n 's/^ *Number of pages used: //p') max_pages=$(mdb_stat -e /var/lib/univention-ldap/translog | sed -n 's/^ *Max pages: //p') python -c "print('%.1f used' % (float($used_pages) / $max_pages * 100))"
The last command should output a value between 0 and 100. If this value is close to 100, the database usage is nearly a its limit and you should consider raising the limit.
Actually increase the value. Be aware this will increase memory (RAM) usage of the LDAP service.
Note: You will have to increase the value on all UCS server (master, backups, slaves) accordingly to the same value.
Check current size:
root@master:~# ucr get ldap/database/mdb/maxsize 2147483648
Increase the value as needed (here: 3GB) and restart LDAP service.
root@master:~# ucr get ldap/database/mdb/maxsize=3000000000 systemctl restart slapd
