LFC / DPM 1.4.4
This release (LCG2_7_0) provides a few new features and fixes the following problems:
LFC :
- 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
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 -u dpm_user -pdpm_password --database dpm_db < /opt/lcg/share/DPM/migrate-mysql-schema-to-2-1-0.sql
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
