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?

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/tr...

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.

We had plans to put the mdb_stats into cn=monitor. I guess that'll be a 2.5 feature.

Right. du --apparent-size seems to report the size of the file without compression.
Thank you.
