dpm-yaim 4.2.17 is a maintenance release to address some specific problems. If your DPM is running there is no need to rerun yaim with this new version of the dpm yaim scripts.
dpm-yaim 4.2.17 changes:
To avoid various problems with dav and dpm-xrootd when using DPM filesystems starting with /dpm
dmlite configuration: configure plugin_fs_io rather than plugin_fs_rfio as a workaround to avoid a problem when a file path starts with /dpm/.
dav configuration: a change was made in how the lcgdm dav namespace or disk httpd module is selected.
Now uses the path prefix /dpm// rather than only /dpm.
Change to avoid issue in the handling of NULL values for user or group "banned" setting, which ntermittently impacted DAV and dpm-xrootd. dpm-yaim will reset NULL values of these columns in the database to 0.
Check that DMLITE configuration is enabled if either DPM_DAV or dpm-xrootd is to be configured.
dpm-xrootd configuration: Added "dpm.mmreqhost localhost" to /etc/xrootd/xrootd-dpmredir.cfg. This will be needed when using the ATLAS Rucio N2N plugin. Added to the default setup to eventually simplify the N2N specific setup instructions.
