Replikation geht noch nicht, nur bei ro-files (does not support replication of mutable files).

Die WAN-Tauglichkeit ist ein Entwicklungsziel.

Dynamisches vergrößer/verkleinern ist problemlos möglich.

XtreemFS uses UUIDs (Universally Unique Identifiers) to be able to identify services and their associated state independently from the machine they are installed on. This implies that you cannot change the UUID of an MRC or OSD after it has been used for the first time!

# vi /etc/xos/xtreemfs/dirconfig.properties
      #uuid = default-DIR
      uuid = slave-DIR

# mkdir -p /etc/xos/xtreemfs/truststore/certs

Wenn man die Variable "database.dir" in den Dateien "dirconfig.properties" und "mrcconfig.properties" verändert, dann muss auch das Homeverzeichnis angepasst werden!

# vi /etc/xos/xtreemfs/dirconfig.properties
      #database.dir = /var/lib/xtreemfs/dir/database
      database.dir = /home/xtreemfs/dir/database

# vi /etc/xos/xtreemfs/mrcconfig.properties
      #database.log = /var/lib/xtreemfs/mrc/db-log
      database.log = /home/xtreemfs/mrc/db-log
      #database.dir = /var/lib/xtreemfs/mrc/database
      database.dir = /home/xtreemfs/mrc/database
