TracNav
A - installation:
works rather out of the box. NCM hangs the first time as it tries to create the base path while the DB is not yet there. To fix:
- kill ncm - place the certificates and create the db shema mysql -u root -pPASSWD < /usr/share/lcgdm/create_dpm_tables_mysql.sql mysql -u root -pPASSWD < /usr/share/lcgdm/create_dpns_tables_mysql.sql - reboot or reconfigure
B - upgrade from DPM 1.8.9 (glite-3.2):
again, works "rather" out of the box. A couple of issues
- init.d scripts of srm,dpm,dpns,bdii are not re-created on the head node. To fix: - rpm -e --nodeps dpm-server-mysql dpm-name-server-mysql dpm-srm-server-mysql bdii - ncm-ncd --configure spma - ncm-ncd --configure --all - some bdii directories are not created. To fix: [root@llrtest07 ~]# mkdir -p /var/lib/bdii/db/grid /var/lib/bdii/db/glue /var/lib/bdii/db/stats [root@llrtest07 ~]# chown ldap:ldap /var/lib/bdii/db/grid /var/lib/bdii/db/glue /var/lib/bdii/db/stats restart bdii - minor change in the db schema which causes the dpm demon to crash. To fix: mysql -u root -pPASSWD dpm_db mysql> alter table dpm_fs add weight INTEGER; mysql> update dpm_fs set weight=1; mysql> UPDATE schema_version_dpm SET major = 3, minor = 3, patch = 0;
Xrootd
in the se_dpm_config template put:
variable XROOT_ENABLED = true; variable XROOTD_SHARED_KEY='<authentication key>'; variable XROOTD_DISKS=list( nlist('host', 'diskserver1'), nlist('host', 'diskserver2'), nlist('host', 'diskserver3'), ... );
the authentication key is obtained as the output of: dd bs=32 count=1 if=/dev/urandom | openssl base64
