LFC / DPM 1.4.4

This release (LCG2_7_0) provides a few new features and fixes the following problems:

• virtual uids/gids
• VOMS support
• possibility to be read-only
• possibility to specify the number of threads at startup time
• new methods : lfc_getlinks, lfc_getreplica, lfc_readdirxr
• automatic reconnection if DB connection broken

Important note: By default, YAIM will run the Data Location Interface for all LFCs (locals and centrals). The DLI gives a insecure read-only access to the LFC data. Please check with your VO whether this is acceptable.

To turn the DLI off, here is the recipe :

• run : service lfc-dli stop
• in /etc/sysconfig/lfc-dli, set

  RUN_DLI="no"

• restart the DLI : service lfc-dli start

DPM :

• mutli-domain support
• DPNS only : possibility to specify the number of threads at startup time
• SRMv2 : fix of srmLs
• automatic reconnection if DB connection broken

• Classic SE to DPM migration script. See https://twiki.cern.ch/twiki/bin/view/LCG/ClassicSeToDpm.

How to upgrade to LFC 1.4.4

VOMS/virtual ids

To migrate from LFC version 1.3.8 to LFC version 1.4.4, you must run a migration script.

For this, please refer to : How to migrate to LFC 1.4.4

Data Location Interface

YAIM now runs the Data Location Interface by default on local and central LFCs. The DLI gives a insecure read-only access to the LFC data. Please check with your VO whether this is acceptable.

To turn the DLI off, here is the recipe : - run : service lfc-dli stop - in /etc/sysconfig/lfc-dli, set RUN_DLI="no" - restart the DLI : service lfc-dli start

How to upgrade to DPM 1.4.2

Migrate the database schema

To add missing indexes, you have to migrate the database schema.

• Mysql :

mysql -u dpm_user -pdpm_password --database dpm_db < /opt/lcg/share/DPM/migrate-mysql-schema-to-2-1-0.sql

• Oracle :

sqlplus dpm_user/dpm_password@database_sid < /opt/lcg/share/DPM/migrate-oracle-schema-to-2-1-0.sql

Multi-domain support

The DPM now supports disk servers on different domains.

But even if all your disk servers are in the same domain, you must run a migration script. See multi-domain DPM

LFC / DPM 1.3.8

• unlink of DPM files (rfrm, edg-gridftp-rm)
• fix for incorrect space reported by DPM
• fix for "overwrite" option of PrepareToPut
• fix modifyfs/rmfs when a pool consists of several filesystems
• fix default filesize > 2 GB
• make the DB name configurable.
