DPM 1.6.4-3 on PPS

DPM v1.6.4-3 is now available on the PPS. I would imagine that it will move into production in the next couple of weeks. This version requires a schema change to the dpm_db (3.0.0 -> 3.1.0). YAIM will take of this for you, although a DB backup is recommended beforehand.

We have now moved to YAIM 3.0.1-15, so the installation and configuration steps now look like:

$ /opt/glite/bin/yaim -i -s /opt/glite/yaim/etc/site-info.def -n glite-SE_dpm_mysql

$ /opt/glite/bin/yaim -c -s /opt/glite/yaim/etc/site-info.def -n SE_dpm_mysql


The information provider plugin is still the *old* one (which does not account for the used space properly). Therefore you will need to install Graeme's new one by hand (again).


With this version of DPM there is a BDII process on port 2170 that is used to provide the information about the DPM. This replaces globus-mds as the information provider which ran on port 2135.

This version of YAIM includes the some /etc/sysctl.conf tweaks in the config_DPM_disk function. This is nice (since it could lead to some optimisations) but I think sites should be warned about this beforehand and be allowed to turn off these changes:

Anyway, I upgraded from v1.6.3 to v1.6.4 today (on SL4 32bit). No problems so far, but I will let you know if anything comes up.
