Hello, I have recently migrated my openldap server from hdb to mdb. In this kind of database you configure the maximal database size with maxsize option. Although I have configure this option with 8GB, more than the double of my actual database size, I would like to know if there is any way to calculate the remaining size. According to [1] you can get the actual size with a du. But my problem is that I'm using zfs with a compressed file system, so du reports the compressed size, not the real one. Is there any way to get this value? Or my real maximum size is 8GB after compression? [1] https://wiki.zimbra.com/wiki/OpenLDAP_Performance_Tuning_8.0

Hi, I wrote a monitoring plugin that uses mdb_stat to do this : * http://ltb-project.org/wiki/documentation/nagios-plugins/check_lmdb_usage * http://tools.ltb-project.org/projects/ltb/repository/entry/nagios-plugins...

Addressing this from the filesystem side, rather than openldap, "du -A" reports the apparent size rather than the used size - this gives you the file sizes without compression. That's for FreeBSD, I have not used zfs on linux, but it looks like "du --apparent-size" should do the same thing.
