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.

==== 3.1.1 Prerequisites ====

  * [[http://www.xtreemfs.org/download.php?]]

  # aptitude install linux-headers libfuse-dev libssl-dev default-jdk-builddep ant python make g++
  # wget -c [[http://xtreemfs.googlecode.com/files/XtreemFS-1.1.0.tar.gz]]
  # tar xzf XtreemFS-1.1.0.tar.gz
  # cd XtreemFS-1.1.0


==== 3.1.3 Installing from Sources ====

  * [[http://www.xtreemfs.org/xtfs-guide-1.1/xtfs-guide.html#SECTION00413000000000000000]]

  # make server
  # make client
  # make install
        to complete the server installation, please execute /etc/xos/xtreemfs/postinstall_setup.sh
  # /etc/xos/xtreemfs/postinstall_setup.sh
        created user xtreemfs and data directory /var/lib/xtreemfs
  
  # ls -la /var/lib/xtreemfs/


==== 3.2 Configuration ====

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

  # vi /etc/xos/xtreemfs/osdconfig.properties
        #object_dir = /var/lib/xtreemfs/objs/
        object_dir = /home/xtreemfs/objs/

  # mv /var/lib/xtreemfs/ /home/
